Abstract

Purpose: To compare the ocular higher-order aberrations and visual functions of the implanted four aspheric IOLs one month after surgery.

Methods: Patients who underwent 2.4mm small-incision phacoemulsification and implantation with SN60WF,ZCB00,NY-60 or W-60 and could be followed up at least 1 month were eligible for the study.Corneal, internal and ocular higher-order aberrations were measured with 6mm pupil size using KR-1W wavefront analyzer (TOPCON) before and 1 month after surgery. From the Zernike coefficient,we calculated root mean square of coma-like and spherical-like aberrations. Also, the change of the Zernike coefficient Z40 was evaluated. Other outcome measures were best corrected visual acuity (BCVA) and contrast sensitivity.

Results: Seventy seven eyes of 54 patients were evaluated. Postoperative ocular spherical-like aberration of the W-6 group was statistically significantly higher than the other 3 groups.Except postoperative ocular spherical-like aberrration,there were no statistically significant differrences in higher-order aberrations, BCVA and contrast sensitivity among 4 groups. In terms of the Zernike coefficient Z4 0, 17% of the patients had negative ocular spherical aberration postoperatively.

Conclusions: Each four aspheric IOLs has negative spherical aberration,-0.20μm,-0.27μm,-0.18μm or - 0.13μm respsctively, but we couldn't find any differences in BCVA and contrast sensitivity among these IOLs. This study suggests that selecting aspheric IOLs randomly may not result in clinical differences.
