Neeti Parikh, MD Fuxiang Zhang, MD Department of Ophthalmology Henry Ford Hospital A Comparison Of Patient Satisfaction With Modified Monovision Versus The ReSTOR ® Intraocular Lens *The authors have no financial interest in the material presented

PURPOSE To compare patient satisfaction of visual function with modified monovision vs. with ReSTOR ® lens implantation  Monovision: a type of presbyopic correction in which one eye is corrected for distance and the other eye for near  Modified monovision: smaller refractive difference between the two eyes (Between D anisometropia )  ReSTOR: a multifocal intraocular lens that provides patients with a range of vision, near through distance  ReSTOR® : a multifocal intraocular lens that provides patients with a range of vision, near through distance

METHODS Part 1: Retrospective Chart review  Charts for patients who had cataract surgery between January 2005 and January 2007 from one clinical practice in the Henry Ford Health System reviewed Inclusion criteria: Bilateral cataract extraction and implantation of either a conventional intraocular lens with the goal of modified monovision or an AcrySof ® ReSTOR ® lens Exclusion criteria: Other ocular co-morbidities (moderate to severe diabetic retinopathy, glaucoma with significant visual field defects or optic nerve damage, ARMD) or Toric IOL implantations  Minimum of 1 month follow up post operative visit  Preoperative refraction, keratometry, IOL calculations  All patients underwent conventional phacoemulsification and in the bag implantations with Alcon SN60 WF or SA60 AT lens or ReSTOR ® : SN60D3 ReSTOR  Postoperative uncorrected visual acuity (distance and near), postoperative refraction Part 2: Patient satisfaction survey  Visual function questionnaire- 25 (VFQ-25), validated by the National Eye Institute  Amended to include questions about glare, halos, intermediate vision, and use of glasses after surgery  Completed by patients months postoperatively

RESULTS Modified Monovision  67 charts reviewed, 1 surgeon  57 completed survey (85%)  31% male  69% female  94% Caucasian, 6% other  Mean Age: 73 (SD =7 years)  modified monovision= D anisometropia Mean=1.4D,standard deviation=.3D 81% D ReSTOR ®  76 charts reviewed, 8 surgeons  68 completed survey (89%)  40% male  60% female  97% Caucasian, 3% other  Mean Age 68 (SD =12 years )

Freedom from glasses Modified Monovision: 14% of patients (who completed survey) never wear glasses ReSTOR® : 84% of patients (who completed survey) never wear glasses Modified Monovision ReSTOR ® Distance61%8% Intermediate67%19% Near62%18% Driving53%9% p<.001for all Use of glasses among “satisfied” patients (% pts who had little to no difficulty with driving, distance, intermediate, or near activities but still used glasses for these activities):

CONCLUSIONS/DISCUSSION  Uncorrected distance visual acuity better in ReSTOR ® group (20/40 or better)  No statistical difference in uncorrected near acuity (J3 or better) between the two groups  Modified monovision patients have more dependence on glasses (for all activities) Modified monovision falls short of correcting for full monovision  Average of only 1.4 D difference between 2 eyes  May not be enough to achieve high rate of glasses independence  No preoperative tolerance test performed for this group This is the reason for the modified approach to monovision in these patients Astigmatism  ReSTOR ® patients with ≥ 1 D of astigmatism treated with limbal relaxing incisions  26% of modified monovision patients had ≥ 1 D of preoperative astigmatism that was not corrected  Patients with toric implants who had monovision were excluded from this study

CONCLUSIONS/DISCUSSION  Monovision patients more likely to wear glasses, but still very satisfied No statistical difference in satisfaction scores for driving, distance, or reading between 2 groups Statistically significant higher satisfaction score in modified monovision group for intermediate (computer) vision Modified monovision patients had no out of pocket costs for the surgery ( ReSTOR® cost to patient = $1895 per eye )  Modified monovision patients more likely to be willing to pay for glasses
