Long-term follow-up of a multifocal apodized diffractive intraocular lens after cataract surgery.

摘要

PURPOSE: To report the long-term performance of the AcrySof ReSTOR SA60D3 intraocular lens (IOL) after cataract surgery. SETTING: University Hospital Maastricht, Maastricht, The Netherlands. METHODS: This prospective clinical trial comprised 44 eyes (22 consecutive patients) having cataract surgery with implantation of the ReSTOR IOL. Monocular and binocular uncorrected distance visual acuity, best corrected distance visual acuity, uncorrected near visual acuity, best distance-corrected near visual acuity, spectacle dependence, undesired visual symptoms, patient satisfaction, and incidence of posterior capsule opacification were analyzed 6 months and 3 years postoperatively. RESULTS: The mean uncorrected distance acuity (logMAR) was 0.046 +/- 0.099 at 6 months and 0.115 +/- 0.173 at 3 years and the mean best corrected distance acuity, -0.040 +/- 0.075 and -0.018 +/- 0.093, respectively. Binocular uncorrected and best-corrected near acuities (logMAR) were 0.009 +/- 0.029 at 6 months and 0.014 +/- 0.035 at 3 years. All patients achieved a binocular uncorrected and best distance-corrected near acuity of 20/25 or better at 6 months and 3 years. On a quality-of-life questionnaire, patients reported good distance, intermediate, and near acuity without complaints of severe glare or halos. Complete spectacle independence for distance and near acuity was achieved by 83.7% and 81.9% of patients, respectively, at 6 months and 85.0% and 75.0% of patients, respectively, at 3 years. Four eyes (9.1%) required neodymium:YAG capsulotomy. CONCLUSIONS: Cataract surgery with the AcrySof ReSTOR SA60D3 IOL provided good, stable distance and near visual acuities over a 3-year follow-up, leading to low spectacle independence and high patient satisfaction.
