[Short-term observation of Acrysof Toric intraocular lens for correction of preoperative astigmatism in patients having cataract surgery].
Zhonghua Yan Ke Za Zhi. 2010 Jun; 46(6):513-7.ZY

Abstract

OBJECTIVE

To evaluate the results of Toric intraocular lens (IOL) for correction of preoperative astigmatism in patients having cataract phacoemulsification.

METHODS

It was a prospective case series study. Seventy-one eyes (60 patients) had implantation of Acrysof Toric IOL. logMAR uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), preexisting corneal astigmatism, residual refractive sphere and cylinder, and toric IOL axis were measured. Four residual astigmatism models were compared according to their axis postoperatively: neutral, against-the-rule (ATR, 180 ± 15 degrees), with-the-rule (WTR, 90 ± 15 degrees) and oblique (OB, 45/135 ± 30 degrees). Rank sum test and Friedman test was used to analyze these data.

RESULTS

Three months postoperatively, the median distant UCVA increased significantly from 0.80 to 0.20, residual refractive astigmatism decreased significantly from 2.02 D to 0.67 D. The mean Toric IOL axis rotation was 1.63 ± 1.83 degrees, with rotation less than 5.00 degrees in 96% of eyes. For uncorrected near visual acuity, group ATR fared the best results and the difference between group ATR and groups WTR, neutral and OB was statistically significant. For UCVA, there was no statistically significant difference between group ATR and groups neutral and OB.

CONCLUSIONS

Acrysof Toric IOL implantation is a predictable, safe and effective method to correct preexisting corneal astigmatism in patients having cataract phacoemulsification. A pseudophakic eye after Acrysof Toric IOL implantation with low residual ATR myopic astigmatism is beneficial for obtaining a better uncorrected near and distant visual acuities.
