Outcomes and patient satisfaction after presbyopic bilateral lens exchange with the ResTOR IOL in emmetropic patients.

Abstract

PURPOSE:

To assess efficacy, safety, predictability, stability, and patient satisfaction after presbyopic lens exchange in emmetropic patients.

METHODS:

A prospective, nonrandomized, masked, observational case series (self-controlled) of 46 emmetropic eyes of 23 consecutive patients (age range: 50 to 60 years) after presbyopic lens exchange with bilateral AcrySof ReSTOR Natural (SN60D3) intraocular lens (IOL) (Alcon Laboratories Inc) implantation were evaluated. Mean spherical equivalent refraction (SE) was -0.04±0.14 diopters (D) (range: +0.25 to -0.25 D). Monocular and binocular uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA), distance-corrected near visual acuity (DCNVA), and patient satisfaction were recorded preoperatively and 6 months after surgery.

RESULTS:

At 6 months postoperative, efficacy index at distance was 1.00. No eye lost ≥2 lines of CDVA, 5 eyes lost 1 line, 24 eyes did not change after surgery, 14 eyes gained 1 line, and 3 eyes gained 2 lines of visual acuity. Safety index at distance was 1.03. All eyes had a manifest SE within ±0.50 D of emmetropia. Mean postoperative SE was +0.14±0.22 D (range: -0.25 to +0.37 D). No eye lost >2 lines of DCNVA, 1 eye lost 2 lines, 3 eyes lost 1 line, 34 eyes did not change after surgery, and 8 eyes gained 1 line of visual acuity. Uncorrected near visual acuity was 0.95±0.07. Safety and efficacy indexes at near were 1.01 and 1.03, respectively. A patient satisfaction questionnaire showed that patients had a high level of satisfaction after presbyopic lens exchange surgery.

CONCLUSIONS:

Presbyopic lens exchange with implantation of the ReSTOR multifocal IOL in emmetropic eyes is an effective and safe procedure for presbyopia correction.
