Abstract

PURPOSE: To evaluate near and far visual outcomes, subjective visual symptoms, and patient satisfaction with AcrySof(R) ReSTOR(R) diffractive multifocal intraocular lenses (IOL), and to study the reasons for postoperative dissatisfaction.
METHODS
Twenty-three eyes of 19 patients received phacoemulsifications and implantation of AcrySof(R) ReSTOR(R) IOL. The main outcome measures, taken at postoperative 1 day, 1 week, 1 month, and 3 months, were uncorrected and corrected near and distant visual acuity, refractory errors, subjective visual symptoms (glare, halo, and night vision), and satisfaction.
RESULTS
At the 3-month postoperative visit, the mean uncorrected near and distant visual acuities were 0.59+/-0.24 (0.25+/-0.22 LogMAR unit) and 0.78+/-0.27 (0.13+/-0.10 LogMAR unit), respectively. In addition, patients' satisfaction with uncorrected near vision, intermediate vision, far vision, and general visual performance were better than their satisfaction with night vision. Glare and halos were reported as severe by only 10.2% and 5.3% of patients, respectively. The seven eyes with poor patient satisfaction included eyes with a high incidence of preoperative ocular diseases or preoperative and postoperative high corneal astigmatisms of more than 1.0 diopter.
CONCLUSIONS
The AcrySof(R) ReSTOR(R) IOL demonstrated good near and distant visual acuity with good patient satisfaction. Previous ocular disease, corneal astigmatism less than 1.0 diopter, and patient lifestyle should be considered to enhance patient satisfaction.
