How to be Fabulously Successful with Premium IOL’s Randy J. Epstein, MD “Cataract” Surgery vs. Refractive Lens Exchange “R.L.E.” Professor, Dept. of Ophthalmology Rush University Med Med. Center Center, Chicago IL CEO, Chicago Cornea Consultants, Ltd. Chicago/Highland Pk./Hoff. Est., IL Similarities: Surgical procedure IOL s IOL’s Differences: Indication for surgery Who is paying The Key Elements of Success “Up-charging” for enhanced services: “UPGRADES” Your entire practice must have a “refractive mindset” in order to be successful with refractive IOL’s for BOTH groups, (even ( if you JUST do d cataracts), including: 1) Enhanced “customer” orientation 2) Receptive population 3) EASY availability of financing • Now a well established Medicare paradigm • “Concierge” internal medicine practices have solidified the concept, concept which is growing (you get what you PAY for) • Patients are more accustomed to paying “out of pocket” for more of their healthcare needs (“fee for service”) Refractive IOL’s approved by the FDA in active use in USA Good candidates for Multi-focal IOL’s Multi-focals: – Alcon ReSTOR – AMO Technis – B&L Crystalens Torics: – STAAR AA4203TL – Alcon Acrysof SN60T* series • Patient is interested in decreasing dependence on reading glasses- (Steinert, ‘08: “The patient has to care”) • Young cataract patients • Most refractive lens exchange (RLE) patients (especially hyperopes) • Willing to accept possible halos 1 Multi-focal IOL’s: Best for Hyperopic Presbyopes • Easiest to please as they have TWO optical problems • Greatest margin for error • Low risk of RD RLE: My Preferred Refractive Procedure in “Older” Presbyopes (over 60) • Azar study, 2008: LASIK is “OK” • RLE with a multi-focal IOL addresses both distance and near issues most effectivelyy • Treats lens-induced HOA’s and avoids postLASIK disappointment • Eliminates “post-LASIK” IOL calculation hassle for cataract surgery • (Retinal consults for high myopes) Subjective Exclusion Criteria for Bad candidates for Multi-focal IOL’s • Astigmats (>1.5D of corneal astigmatism) • Macular pathology (ERM’s, drusen) • Abnormal corneas – Keratoconus, prior refractive or corneal surgery – Ocular surface disease (EBMD, dry eyes) Multi-focal IOL’s • • • • Hypercritical patients Patients with unrealistic expectations Occupational night drivers ? Pilots • Mono-focal IOL in the other eye? • Glasses-wearing low myopes (they like to read ‘sc’ and IOL’s never exceed this) Relative Contraindications for Toric IOL’s- NOT MANY! • Fewer ocular issues- (OK to use with GLC, ARMD, post-ops, etc.). KC +/- now… • Ocular surface disease (EBMD (EBMD, dry eyes) • ? High residual astigmatism in other eye (unless you are prepared to deal with it) • Surgical complications Multi-focal IOL’s: Pre-op considerations • 1) Pre-op topography is essential • 2) ? Match IOL color in contra-lateral y ((chromophore/clear) p ) ?? multifocal eye • 3) Plan/discuss need for N/C post-op PRK/LASIK “touch-ups” in advance. • (This is factored into the “up-charge”). 2 Refractive IOL’s: Pre-op considerations: Our patient education routine Our Patient Education Carrels: Patient Education Concepts, Inc. • All patients watch Patient Education Concepts p ((P.E.C.)) DVD or computer p program, and take the quiz (for documentation) while they are dilating • Brochures, etc. • Detailed, written informed consent • Finance plans (CareCredit, etc.) Computer version Alcon “ReSTOR” +4.00D add Multifocal IOL FDA Approval: April, 2005 • “Pseudo-accommodative” • Reading center weighted • Light Li ht energy is i equally ll divided di id d between b t distance di t and near for small pupils • Becomes distance-dominant for large pupils • Aspheric optics • Near point TOO CLOSE for many patients AcrySof® ReSTOR® Aspheric IOL Design AcrySof® IQ ReSTOR® +3.0D add IOL The AcrySof® ReSTOR® Aspheric IOL is designed with negative spherical aberration. SN6AD3 SN6AD1 Add Power: +4.0 D Spectacle Plane: +3.2 D Range: +10.0 D to +34.0 D A-Constant: 118.9 Add Power: +3.0 D Spectacle Plane: +2.5 D Range: +6.0 D to +34.0 D A-Constant: 118.9 18 3 Aspheric Optics with AcrySof® ReSTOR® Aspheric “Deliberate use of unequal adds with ReSTOR” • Osher JCRS 35:1646, 2009 • Patient #1: ReSTOR +4, had computer problems • Patient #2: ReSTOR +3, and unable to read fine print • Both patients “20/Happy” after getting other IOL in second eye Aspheric IOL Aspheric optics align the light rays to compensate for positive corneal spherical aberration, with enhanced image quality. SN6AD1 Design Characteristics Apodization • “Cutting off the feet” (Greek) • Small pupils: Equal distribution of near and distance Rx • Large pupils: Distance dominant • Utilizes existing IQ ReSTOR® IOL +4.0 D platform with identical asphericity, energy distribution profile, and shape factor • Add power modified to +3.0 D – 9 diffractive steps vs. 12 diffractive steps – Slightly wider step spacing to modify the add power 22 Uncorrected Intermediate Photopic VAs Average Near Best Distance 100 90 80 70 60 50 40 30 20 10 0 38 Centim meters (cm) % off Subjects All Implanted, 3 month postoperative, 50 cm 36 34 32 30 28 26 20/25 or better 20/32 or better 20/40 or better Uncorrected IQ ReSTOR® IOL +3.0 D [N=138] IQ ReSTOR® IOL +3.0 D [N=138] IQ ReSTOR® IOL +4.0 D [N=131] IQ ReSTOR® IOL +4.0 D [N=131] Provides a one line or more improvement in binocular intermediate VA.

Refractive IOL Complications • Power errors • Mis-communications (mono-vision, etc.) • Surgical complications – Back-up IOL’s need to be available (on axis surgery especially critical for astigmats as there IS no backup for toric IOL) – Alcon MN60D3= 3 piece multifocal • Post-op complications 5 Long-Term ReSTOR- JCRS 9/08: 80% spectacle independent at 3 yrs. Multifocal IOL’s: Post-op issues • Have Alcon’s minus Rx glasses handy for patients to use for demonstration • Use topography to illustrate residual astigmatism, which is usually the issue • Low threshold for offering NO CHARGE PRK/LASIK touch-ups (included with ‘up-charge’) When to fix astigmatism? Always takes precedence over presbyopia “You have three problems, we can only fix two” (in the following order): – 1) Cataract – 2) Astigmatism – 3) Presbyopia Common “Astigmatism Trap”: Refractive- ATR, K-WTR Common “Astigmatism Trap” Example • • • • MR= +1.00 + 1.00 x 180 OU WITH the-rule astigmatism on topography WITH the rule astigmatism on IOLMaster = “Lenticular Astigmatism”!
