Abstract
Purpose: :
To evaluate visual function, quality of life and overall satisfaction of patients implanted with the AcrySof® ReSTOR® Aspheric IOL model SN6AD3 , a multifocal intraocular lens that provides patients with a range of vision, near through distance.
Methods: :
Randomly selected charts of patients who underwent bilateral cataract extraction with implantation of the AcrySof® ReSTOR® lens were pulled. All patients were at least 7-12 months post- operative with an average of 5 months. The exclusion criteria were the presence of other ocular co-morbidities such as moderate to severe diabetic retinopathy, age-related macular degeneration and glaucoma with significant visual field defects or optic nerve damage. Eleven patients who fit the criteria were included in the study. The charts were reviewed and the post-operative uncorrected near and distance visual acuity was recorded. Patients were then orally administered a visual function questionnaire- 25 (VFQ-25), validated by the National Eye Institute and amended to include questions about glare, halos, lens exchange, intermediate vision, and use of glasses after surgery.
Results: :
The mean age of the patients was 62 years. Fifty-four percent of the patients had distance vision improved to 20/20 or better. Eighty-seven percent of the patients had vision improved to 20/30 or better with the worst vision being 20/40. Ninety-four percent of the patients had near vision that was J +1 or better. These results for the visual acuity were seen as early as one month post-operative.Results of patient satisfaction with the procedure are shown in Chart 1.CHART 1: Patient Satisfaction with Procedure
Conclusions: :
Bilateral cataract extraction with implantation of the AcrySof® ReSTOR® Aspheric IOL model SN6AD3 objectively improved near, intermediate and distant vision. The majority of patients had subjective satisfaction, with a 100% for distance and an overall satisfaction of 80%. The drawbacks include 10% of patients needing to use contacts or glasses occasionally, night-time halos and glares experienced by 44% of the patients with 10% of these patients having difficulty with night-time driving.
