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