INDICATIONS: The AcrySof® IQ ReSTOR® Posterior Chamber Intraocular Lens (IOL) is intended for primary implantation for the visual correction of aphakia secondary to removal of a cataractous lens in adult patients with and without presbyopia, who desire near, intermediate and distance vision with increased spectacle independence. The lens is intended to be placed in the capsular bag. WARNINGS/PRECAUTIONS: Careful preoperative evaluation and sound clinical judgment should be used by the surgeon to decide the risk/benefit ratio before implanting a lens in a patient with any of the conditions described in the Directions for Use labeling. Physicians should target emmetropia, and ensure that IOL centration is achieved. Care should be taken to remove viscoelastic from the eye at the close of surgery. Some patients may experience visual disturbances and/or discomfort due to multifocality, especially under dim light conditions. As with other multifocal IOLs, visual symptoms may be significant enough that the patient will request explant of the multifocal IOL. Spectacle independence rates vary with all multifocal IOLs; as such, some patients may need glasses when reading small print or looking at small objects. Clinical studies with the AcrySof® ReSTOR® lens indicated that posterior capsule opacification (PCO), when present, developed earlier into clinically significant PCO. Prior to surgery, physicians should provide prospective patients with a copy of the Patient Information Brochure available from Alcon for this product informing them of possible risks and benefits associated with the AcrySof® IQ ReSTOR® IOLs. Studies have shown that color vision discrimination is not adversely affected in individuals with the AcrySof® Natural IOL and normal color vision. The effect on vision of the AcrySof® Natural IOL in subjects with hereditary color vision defects and acquired color vision defects secondary to ocular disease (e.g., glaucoma, diabetic retinopathy, chronic uveitis, and other retinal or optic nerve diseases) has not been studied. Do not resterilize; do not store over 45° C; use only sterile irrigating solutions such as BSS® or BSS PLUS® Sterile Intraocular Irrigating Solutions.

INDICATIONS: The AcrySof® IQ Toric posterior chamber intraocular lenses are intended for primary implantation in the capsular bag of the eye for visual correction of aphakia and pre-existing corneal astigmatism secondary to removal of a cataractous lens in adult patients with or without presbyopia, who desire improved uncorrected distance vision, reduction of residual refractive cylinder and increased spectacle independence for distance vision. WARNING/PRECAUTION: Careful preoperative evaluation and sound clinical judgment should be used by the surgeon to decide the risk/benefit ratio before implanting a lens in a patient with any of the conditions described in the Directions for Use labeling. Toric IOLs should not be implanted if the posterior capsule is ruptured, if the zonules are damaged, or if a primary posterior capsulotomy is planned. Rotation can reduce astigmatic correction; if necessary lens repositioning should occur as early as possible prior to lens encapsulation. All viscoelastics should be removed from both the anterior and posterior sides of the lens; residual viscoelastics may Optical theory suggests that high astigmatic patients (i.e. > 2.5 D) may experience spatial distortions. Possible toric IOL related factors may include residual cylindrical error or axis misalignments.

McDonnell, MD director of the Wilmer Eye Institute, Johns Hopkins University School of Medicine, Baltimore, and chief medical editor of Ophthalmology Times. He can be reached at 727 Maumenee Building 600 N. Wolfe St. Baltimore, MD 21287-9278 Phone: 443/287-1511 Fax: 443/287-1514 E-mail: [email protected] “What is negotiation but the accumulation of small lies leading to advantage?” —Felix Dennis “ELLEN PAO IS SWIFTLY emerging as the new face of feminism in the United States,” declared a recent article in the business/finance literature. That name may ring a bell to some readers because of Pao’s recent lawsuit against her former employer. She sued for $160 million ($16 million in lost wages and $144 million in punitive damages) after not being promoted within one of Silicon Valley’s biggest venture capital firms, claiming that the decision was the result of gender discrimination. The lawsuit received a lot of attention in the press because of the facts that sounded less like something from the business school literature and more like something in “Playboy” (or so I imagine). Numerous salacious details came out in the testimony, including romantic trysts and employees wearing bathrobes showing up at their colleagues’ hotel room doors. These are the details inquiring minds want to know. The jury ultimately weighed in by deciding that the plaintiff had not been a victim of gender discrimination. TAKING TALKS OFF THE TABLE Pao is currently the interim chief executive officer of Reddit, an entertainment, social networking, and news website. What is attracting attention and some praise is Pao’s establishment of a new policy that no longer allows new hires to negotiate their salaries. “We come up with an offer that we think is fair . . . we aren’t going to reward people who are better negotiators with more compensation,” Pao explained. In an article about this change, “Pao defended her move based on studies that have shown that when women negotiate, they don’t fare as well as their male counterparts.” According to a study by Linda Babcock, a professor at Carnegie Mellon University, “when women negotiate, both men and women are less likely to want to work with them. Men, on the other hand, are much more respected for their negotiation skills. For women, it’s generally a lose-lose situation.” W H AT’S FAIR IS FAIR I agree that this approach has a lot of merit. Why shouldn’t people earn a fair degree of compensation, in a transparent manner, for their work, and why should a company that has ten people doing the same job be paying them ten different amounts? In an ophthalmology practice or academic department, should hiring a new associate resemble a visit to a car dealership, in which an applicant willing to delay and engage in protracted discussions be rewarded financially relative to his or her equally well-trained and productive colleague? How about a system that clearly states how base and bonus compensation are determined and let employees—through their actions and measurable productivity—determine their compensation, irrespective of the number of X chromosomes they may possess?

LIVE BETTER. 8 JUNE 1, 2015 :: Ophthalmology Times drug therapy Adherence to drug regimens may increase with generics Switching therapies may help some patients with high co-payments, racial minority groups By Lynda Charters; Reviewed by Joshua D. Stein, MD, MS ANN ARBOR, MI :: GLAUCOMA MEDICATION adherence continues to be a major challenge for some patients, with several studies having reported compliance rates of only 50% or lower, said Joshua D. Stein, MD, MS. Though patients may struggle with their regimens for various reasons, medication cost remains a major factor, said Dr. Stein, associate professor, Department of Ophthalmology and Visual Sciences, University of Michigan, and director, Center for Eye Policy and Innovation, W.K. Kellogg Eye Center, Ann Arbor, MI. Quantifying the impact of cost on adherence can be difficult, however, he explained. For instance, patients may be too embarrassed to admit to financial burdens imposed by drug regimens, either when Dr. Stein filling out research surveys or participating in focus groups. Prostaglandin analogues—among the most frequently prescribed and most effective drugs to treat open-angle glaucoma—require only once-daily dosing and have minimal side effects. However, they are also among the most expensive of the glaucoma drugs, said Dr. Stein, adding that some patients pay more than $100 out of pocket each month. LATANOPROST AS GENERIC With the commercial availability of the first generic prostaglandin analogue, i.e., latanoprost, in 2011 in the United States, some patients saw a considerable and potential reduction in financial burden. In light of this, Dr. Stein and colleagues conducted a study to determine if the availability of latanoprost for open-angle glaucoma had an effect on patient adherence. Specifically, was there an impact to patients’ drug regimens after they switched from a brand-name drug to a generic counterpart, compared with other patients with glaucoma who continued taking a brand-name prostaglandin analogue? Investigators evaluated data from a large, managed-care database of patients aged 40 or regression analysis that were associated with more years who received a diagnosis of open- improved adherence.

Hoffman, MD A EUGENE, OR :: take-home When considering IOL implantation options when there is a lack of capsular support, cataract surgeons should use the approach with which they are most comfortable. They should also continue to learn about new available techniques. broad familiarity of techniques to implant an IOL in the absence of capsular support can be a valuable addition to the surgeon’s virtual toolkit, said Richard S. Hoffman, MD. Available options for managing cases where there is a lack of capsule support include an anterior chamber (AC) IOL, a scleralfixated posterior chamber (PC) IOL, an iris-fixated PC IOL, and intrascleral haptic capture, he noted. “To date, no studies have shown that any one technique is superior to the others,” said Dr. Hoffman, clinical associate profes- sor of ophthalmology, Casey Eye Institute, Oregon Health and Science University, Eugene. Dr. Hoffman cited several studies that supported open-loop AC IOLs and that found this approach posed no greater threat than PC IOLs in the realm of visual outcomes in secondary IOL implantation.1-3 However, some complications with AC IOLs include pain, bullous keratopathy, angle-closure glaucoma, and chronic uveitis. A properly sized, modern Kelman-style open loop AC IOL may help avoid some of these complications and is easily inserted, has a polished finish, and flexible haptics, Dr. Hoffman said. Dr. Hoffman recommended avoiding AC IOLs if a patient has glaucoma, a shallow anterior chamber, insufficient iris tissue, or corneal endothelial dystrophy. If implanting a scleral-fixated IOL, Dr. Hoffman advised operating temporally to reduce astigmatism and using 9-0 Prolene or CV8 Gore-Tex. He did not recommend the use of 10-0 Prolene. He said he also tries to avoid passing sutures at 9 o’clock and 3 o’clock. Two-point fixation is simpler, but four-point fixation allows for greater stability and less lens tilt. Four-point fixation can be associated with an increase in bleeding due to twice as many suture passes through the sclera, Dr. Hoffman said. If using transscleral fixation, users should bury, cover, or rotate scleral knots to prevent conjunctival erosion and the risk for subsequent endophthalmitis, Dr. Hoffman said.

Intrascleral haptic capture is another possible approach for lack of capsule support. Some complications intraoperatively include hyphema, haptic breakage, and a deformed haptic. Early complications include corneal edema, epithelial defects, and iritis, and late complications can include optic capture, IOL decentration, haptic extrusion, and possible re-treatment. Intrascleral haptic capture does have a learning curve, Dr. Hoffman explained. However, surgeons who have become familiar with the technique believe that it is easier to perform intrascleral haptic capture than suturing IOLs to the sclera. SURGEON’S A DV ICE As surgeons decide which approach is best for them, Dr. Hoffman had some advice. “When approaching cases with no capsular support, surgeons should perform the procedure they are most comfortable with,” Dr. Hoffman said. “However, surgeons should become familiar with the various available techniques as there may be instances where one procedure is better than another for a particular patient,” he added. He also cited a study that reviewed the literature from 1980 to 2002 regarding IOL implantation in the absence of capsular support. The study supported the use of open-loop AC, scleral-sutured PC IOLs, and iris-sutured PC IOLS. That study did not find sufficient evidence to suggest the superiority of one technique over another, Dr. Hoffman concluded.4 ■ References 1. Lyle AW, Jin JC.

A PPLY I NG H E AT Dr. Jackson’s technique involves placing the viscoelastic syringes in their sterile packaging into an ultrasonic gel warmer. The device he uses has three temperature settings, and he turns it to the highest level, which can raise the temperature up to 104° F. In order to prevent overheating of the viscoelastic, however, he keeps the lid of the device open. The viscoelastic is kept in the warmer until it is needed for the IOL implantation. By the time the viscoelastic is placed in the eye, the temperature typically is just above normal body temperature range, Dr. Jackson explained. ■ MITCHELL A.

The trifocal IOL distributes 45% of incoming light to distance, 20% to intermediate, and 35% to near (versus 59% to distance and 25.5% to near with the bifocal MFIOL) and features two superimposed bifocal patterns—one with a +1.75 D add and one with a +3.5 D add. The trifocal and bifocal MFIOLs evaluated in the study have similar negative asphericity of –0.11 and –0.10 μm, respectively (Figure 1).

DATA FROM OTHER STUDIES Dr. Nuijts also reviewed data from three other published studies investigating the same trifocal MFIOL in larger groups of eyes (n = 40 to 198),2-4 a cohort study including 60 eyes implanted with another aspheric trifocal MFIOL (AT LISA tri 839MP, Carl Zeiss Meditec), 5 and a randomized trial comparing the latter IOL with a bifocal diffractive MFIOL from the same manufacturer (AT LISA 801, Carl Zeiss Meditec).6 The AT LISA tri 839MP distributes 50% of light for far, 20% for intermediate, and 30% for near. At the IOL plane it provides a near add of +3.33 D and an intermediate add of +1.66 D (Figure 2). Dr. Nuijts reported that distance BCVA outcomes were similar for the two trifocal/one bifocal MFIOLs across all studies. Distancecorrected intermediate visual acuity for the trifocal MFIOLs ranged from 0.06 to 0.17 logMAR and was significantly better with the trifocal MFIOL than the bifocal MFIOL in the direct comparison study (0.06 versus 0.30). Dr. Nuijts also discussed in vitro research comparing the two trifocal MFIOLs, including Special Report ) TECHNOLOGICAL ADVANCES IN a laboratory bench-based study evaluating through-focus modulation transfer function curves.7 Quality of vision was simulated using different sized apertures (2, 3, 3.75, and 4.50 mm) and changing diopters of defocus representing distance (0.0 D = 4 m), intermediate (–1.5 D = 67 cm), and near vision (–3/–3.5 D = 33/29 cm). Results showed the FineVision MicroF trifocal IOL would provide better vision at distance in eyes with larger pupils (3.75 mm) compared with the AT LISA tri 839MP. However, the AT LISA tri 839MP had better results at intermediate and near focal points and was less dependent on pupil size. A clinical trial comparing the FineVision MicroF and AT LISA tri 839MP IOLs in 30 patients who underwent bilateral implantation with the same lens found both trifocal MFIOLS were associated with excellent distance, intermediate, and near visual outcomes at 3 months. 8 Statistically significant differences favoring the FineVision IOL were seen in analyses of distancecorrected intermediate and near visual acuity. “Regrettably, because pupil diameter was not measured, it was not possible to assess the influence of pupil size on the in vivo results of this study,” Dr. Nuijts said. T O R I C , N O N -T O R I C MODELS A toric version of the FineVision trifocal MFIOL is also available in cylinder powers ranging from 1 to 6 D in 0.75-D steps, he noted. A small unpublished study, which has been presented by Roberto Bellucci, MD, compared visual outcomes after bilateral implantation with the non-toric and toric versions of the FineVision trifocal MFIOL. It found no differences in uncorrected or distancecorrected visual acuity at near, intermediate, or distance.

This also reduces the risk of infection or sterilization errors. In addition, surgeons do not have to touch the lens, which could cause damage or contamination. Since the lens is encased in a disposable cartridge and inserter, there is minimal contact with the exterior as well. “It’s a cleaner way of delivering the lens without it being exposed to any potential contaminants,” said Dr. Rocha, adding that the amount of contact with the lens was not an aspect of the study but rather his personal observation. “For me, the most important thing was having a consistent and predictable way of delivering the lens, not wasting time preparing the lens and loading it but having it ready,” Dr. Rocha said. “Just as soon as I’m done, the nurse passes it to me and I inject it.

Previously, the implantable collamer lens (Visian ICL V4C CentraFLOW, STAAR Surgical) was considered by Dr. Mertens only for eyes that were not good candidates for LASIK because they had a thin cornea, dry eye, forme fruste keratoconus, high myopia, or hyperopia, he said. “Now, almost every patient seeking correction of myopia and myopic astigmatism is suitable for the [lens],” said Dr. Mertens, medical director, Eye Center Medipolis, Antwerp, Belgium. “In 2005, the [lens] accounted for only 14% of my refractive surgeries, whereas in 2014, almost 97% of patients seeking refractive surgery were implanted with the [device].” The lens features a 360-μm hole in the center of the optic (Aquaport) that enables more natural aqueous flow between the device and the crystalline lens while also eliminating the need for iridotomies in recipients of this phakic IOL. There are also two similarly sized holes outside the optic—one on either side—that facilitate intraoperative removal of viscoelastic and allow aqueous to flow over a wider surface area of the crystalline lens. “The addition of the penetrating holes elimi- nates the need for an extra procedure preop- at postoperative follow-up visits conducted at eratively and the potential complications that 1, 3, 6 and 12 months, SE was plano in 96% to 99% of eyes.

Despite this, survey respondents indicated that an average 7.2˚ of rotational error would be acceptable, with about one-third of respondents being comfortable with rotational error of 10˚ or more.1 DETER MINE M AGNIT UDE , A X IS Accurate identification of the magnitude and axis of astigmatism is essential in order to choose the right toric power and correctly position it. However, there is no strong consensus about which measurement is the best one on which to base magnitude and axis decisions. In the survey, IOLMaster Ks were most commonly used to determine magnitude, followed by topography and manual Ks. Topography is most heavily relied upon for axis determination, with IOLMaster and Lenstar following. Other methods—including autokeratometry and intraoperative aberrometry—are also used. Though these are all good methods, ideally, one should have at least two different measures from two different devices. Because each device measures slightly differently, the Ks are unlikely to be identical, but close agreement should be sought and significant differences 21 JUNE 1, 2015 :: Ophthalmology Times Special Report ) among measurements should be reconciled to avoid power calculation or axis errors. In selecting the best lens power, it is perfectly acceptable to flip the axis, even though nearly one-half of surgeons say they never do this.1 The conventional wisdom not to flip the axis is based on incisional techniques, when an axis shift could not be reasonably controlled and might result in a large and poorly tolerated error in the opposite axis. However, with an optical lens solution that does not involve relaxing the cornea, surgeons have more control. If the choice were between leaving 0.50 D of residual error at the original axis or 0.10 D at the opposite axis, it would be preferable to flip the axis. The amount of residual error is so small that it will be easily tolerated. MARKING THE AXIS Survey results demonstrate there is also considerable variation in how surgeons mark and align toric IOLs.1 Thirty-seven percent say they rely on anatomical landmarks without marking the cornea or only mark the major axes preoperatively without using any additional axial marking tools during surgery (Figure 1 on Page 20). For accurate placement, the latter is required, at a minimum. Ideally, the principal meridians should be marked preoperatively with the patient in a seated position, and the axis marked intraoperatively with the aid of an axial tool. A fine, durable mark that does not wear off or subtend more than a few degrees should be made. The initial meridian marks can be used as a point of reference intraoperatively, with the patient lying down, to accurately mark the axis of astigmatism even if some cyclorotation has occurred. A Mendez ring or other axial ink marker (one that leaves a fine, durable mark) will be more accurate than surgeons’ estimation of the axis in relation to the principal meridians. Other marking techniques have been developed and shown to be quite accurate. For example, Robert Osher, MD, has described a thermal device that leaves a fine mark. Others have used a Nd:YAG laser to pit the epithelium at the limbus or a sterile needle to create a linear superficial abrasion that can be stained with fluorescein or another dye to highlight the mark. Advanced devices—such as intraoperative aberrometry or surgical guidance systems that incorporate digital registration—are not necessary for implantation of toric IOLs, but they do add greater precision for surgeons who want to maximize outcomes.

Chang, MD BAK ERSF IEL D, CA :: NEW LOW-ADD VERSIONS of the 1-piece multifocal IOL (Tecnis Multifocal, Abbott Medical Optics) afford cataract surgeons an opportunity to customize selection of the presbyopia-correcting IOL according to a patient’s vision needs. In addition, they appear to have the potential to minimize halos, which are intrinsic to multifocal optics, said Daniel H. Chang, MD. Dr. Chang presented results from the FDA study investigating the +2.75 D and +3.25 D add versions of the hydrophobic acrylic, aspheric diffractive multifocal IOL (models ZKB00 and ZLB00, respectively). The theoretical reading distances for the +2.75 D, +3.25 D, and original +4.0 D add Dr. Chang models (ZMB00) are 50, 42, and 33 cm (20, 17, and 13 inches), respectively. The low-add IOLs are based on the same spherical aberration-correcting design and chromatic aberration-minimizing material as the +4.0 D add model. A full diffractive surface provides quality vision and pupil independence with equal light distribution between distance and near, explained Dr. Chang, who was an investigator in the FDA study and is in private practice, Empire Eye and Laser Center, Bakersfield, CA.

All three versions of the multifocal IOL “are great options as each can provide comfortable uncorrected vision at distance, intermediate, and near in more than 80% of patients,” Dr. Chang said. “However, with the two new lowadd versions, I can now provide patients with a personalized best range for near and intermediate vision.” He added that relative to the original +4.0 D add Tecnis multifocal IOL, the lowA BOU T T H E ST U DY add versions seem to be associated The FDA study was a prospective, with fewer night-vision complaints multicenter, bilateral, open-label, and halos in particular. evaluator-masked, modified paralThe FDA study did not directly lel group clinical trial.

In binocular testing, mean logMAR distance uncorrected visual acuity was similar in the control, +2.75 D add, and +3.25 D add IOL groups (–0.01, 0.01, and 0.02), and there was also no significant difference between groups in mean logMAR best-corrected visual acuity at distance (–0.09, –0.07, and –0.06). However, compared with the control group, patients with the +2.75 D and +3.25 D add IOLs implanted had significantly better uncorrected near visual acuity (tested at 40 cm) (0.14 and 0.10 versus 0.44) and distance-corrected near visual acuity (0.17 and 0.11 versus 0.49). Analyses of directed reports of optical/visual symptoms showed none of the patients in the control group was completely spectacleindependent, whereas 61.3% of patients with the +2.75 D add IOL implanted and 75.0% of those with the +3.25 D add IOL implanted said they never wear glasses.

Overall satisfaction with vision without glasses was expressed by 85.6% of controls, 97.2% of the +2.75 D add patients, and 93.3% of +3.25 D add patients. In response to direct questioning, moderate to severe difficulty with halos was reported by TECHNOLOGICAL ADVANCES IN 16% of control patients, 31% of patients with the +2.75 D add IOL, and 43% of those with the +3.25 D version. There was less of a difference between the control and +2.75 D and +3.25 D add multifocal IOL groups in rates of moderate to severe difficulty with glare/flare (19% versus 23% and 31%). When specifically asked about difficulty with night vision, fewer patients had moderate to severe difficulty with night vision in the +2.75 D add multifocal group than in the +3.25 D add multifocal and even the control group (9% versus 16% and 14%, respectively). “Within 1 to 2 weeks after surgery, patients with the low-add . . . multifocal IOLs had little problems with halos and night vision,” Dr. Chang said. “This rapid neuroadaptation phase seems to occur especially with the +2.75 D add version. For that reason, more-demanding patients may particularly benefit from that lens.” The new low-add versions also offer an opportunity for customizing implant decisions using a different add power of the multifocal IOL in the second eye, if indicated by patient preference after the first eye surgery. IOLs “Almost all patients are very happy with their vision after the first surgery and go on to receive the same IOL in the fellow eye,” he said. “Occasionally, however, someone desires a slightly different profile of near and intermediate vision.” This type of variation in near focal points can occur unintentionally when implanting the same add multifocal IOL in both eyes as the result of a slight difference in refractive outcomes, Dr. Chang noted. “We know that patients typically do fine in that situation, and sometimes we even did that intentionally,” he said. “Now with the different versions of [this] multifocal IOL we can approach this type of customization while still targeting a plano refraction in both eyes for the best distance vision.” ■ DANIEL H.

Two of the nation’s top eye institutes have united in an affiliation that will improve patients’ access to leading vision specialists. UCLA Stein Eye Institute and the Doheny Eye Institute — both created by families whose legacies helped shape Los Angeles — have joined forces to offer the best in patient care, vision research and training for future eye specialists. The affiliation adds 14 clinicians and researchers from Doheny to the ophthalmology faculty at the David Geffen School of Medicine at UCLA. Patients can be seen at Doheny Eye Center UCLA offices in Pasadena, Arcadia and Orange County. Both institutes have earned international recognition for the quality of their patient care and research. U.S.News & World Report’s 2015 “Best Hospitals” survey ranked the combined Stein Eye and Doheny Eye institutes as the No. 5 center for ophthalmology based on feedback from specialists in the field. UCLA Stein Eye Institute is a vision science campus dedicated to the preservation and restoration of vision through its internationally recognized programs in research, patient care and integrative education. The center’s ophthalmic specialists treat the full spectrum of vision-threatening conditions, including glaucoma; macular degeneration; diseases of the cornea, retina and vitreous; cataracts and UCLA Stein Eye Institute campus in Westwood UCLA Stein Eye Center in Santa Monica Doheny Eye Center UCLA in Arcadia Doheny Eye Center UCLA in Pasadena Doheny Eye Center UCLA in Orange County uveitis; intraocular inflammation; Graves’ disease; ptosis and lacrimal disease; and eyelid disease. Community outreach efforts range from its mobile eye clinic, which travels to schools, shelters, health fairs and other organizations that assist homeless and low-income families; to programs like Vision IN-School, for vision education; Shared Vision, for the collection and donation of used eyeglasses; the Preschool Vision Screening program; and the Indigent Children and Families program. The Doheny Eye Institute, established in 1947, is a topranked nonprofit organization dedicated to the conservation, improvement and restoration of human eyesight. Recognized as an outstanding center for vision research and education, the Doheny Eye Institute has emerged as a world leader in basic and clinical vision research.

Surgical technique plays a role in the stability and performance of toric IOLs as well. I prefer to use a cohesive viscoelastic. It is important not to over-pressurize the eye. The lens can be injected counterclockwise of its final position and then dialed into correct alignment with the axis marks. Once aligned, I push the IOL gently against the posterior capsule. Finally, all of the ophthalmic viscosurgical device must be carefully removed from behind the lens. With this approach of careful preoperative measurement and marking, intraoperative marking and alignment, and good surgical technique, surgeons can achieve success with toric IOLs to the benefit of their practices and their patients with astigmatism. ■ The enhanced injector system now includes a softened and tumble-polished plunger tip that is 2-mm longer than the previous design, which helps facilitate easier placement in the capsular bag.

Although currently only used with one IOL model, the recent improvements in the injector system and any future modifications could eventually extend its utility to an entire family of lenses, he added. ■ ANIL M.

Measurement of visual acuity in a small subset of patients who underwent binocular implantation showed an average of one additional line increase in best distance-corrected hydrophobic acrylic. The lens and hollow haptics are filled with a proprietary index-matched silicone fluid. The act of accommodation forces fluid from the haptics into the optic, which increases the optic thickness and optical power. During disaccommodation, the fluid flows back into the haptics and the optical power decreases. The lens is 10 mm in overall diameter with an optic that is 6 mm in diameter. The haptics are 3 mm high and the refractive index is 1.48. In this IOL, the optic is suspended between the haptics. The lens is an investigational device and is not available for sale or use in the United States.

Using this as a teaching moment for Shawn, we began reviewing the situation and what it meant throughout the system: > We needed to look at four other clinics and the dynamics of those clinics, and also the clinic that was now short . . . as well as the lead running that clinic. > We looked at the dynamics/demeanor of the physicians at the short clinic. I decreed that one of the technicians, Sara, needed to leave Shawn’s clinic and go to the clinic that was now short. Shawn was to inform Sara, and the case was closed. Or so I thought. Fifteen minutes later, Shawn called to tell me that instead of sending Sara, she had sent Peggy. I was angry for a number of reasons, but tried to temper this so I could try and help Shawn understand the many errors of her ways. She felt she had made an educated decision. While it was educated—it was also ill timed, slightly ulterior, and poorly executed. Peggy is a sweet-tempered and patient technician, but she is newer and still slow with her skills. Going into that fast-paced, crazy clinic was not what I had envisioned. Basically, it was a very poor move and it set Sara up for a pretty scary morning.

Now there were technicians all over the road in the early-morning, rushhour traffic. > Put a new person, who was being sent to “save the day” in the potential line of fire. > Override me, and then informed me of it after the fact.

INDICATIONS: Abbott TECNIS® 1-Piece IOLs are indicated for the visual correction of aphakia in adult patients in whom a cataractous lens has been removed by extracapsular cataract extraction. These devices are intended to be placed in the capsular bag. WARNINGS: Physicians considering lens implantation should weigh the potential risk/benefit ratio for any conditions described in the Directions for Use that could increase complications or impact patient outcomes. Do not attempt to disassemble, modify or alter the device or any of its components. Do not use methylcellulose viscoelastics with the device. Do not implant the lens if the rod tip does not advance the lens or if it is jammed in the cartridge. Do not push the plunger forward to fully advance the lens until ready for lens implantation. Discard if the lens has been fully advanced for more than 1 minute. The lens should not be placed in the ciliary sulcus. PRECAUTIONS: Do not reuse, resterilize, reprocess, or autoclave the device. Do not store in direct sunlight or at a temperature under 5°C (41°F) or over 35°C (95°F). The recommended temperature for implanting the lens is at least 17°C. Low operating room temperatures combined with high IOL diopter powers may require slower delivery. The use of viscoelastics is required when using the device. The use of balance salt solution alone is not recommended. Do not use if the device has been dropped or if any part was inadvertently struck while outside the shipping case. ADVERSE EVENTS: The most frequently reported adverse event that occurred during the clinical trial of the 1-Piece IOL was cystoid macular edema, which occurred at a rate of 3.3%. References 1.
