Comparison of the incidence and visual significance of posterior capsule opacification between multifocal spherical, monofocal spherical, and monofocal aspheric intraocular lenses.
J Cataract Refract Surg. 2009 Jul; 35(7):1234-8.JC

Abstract

PURPOSE

To determine and compare the incidence of posterior capsule opacification (PCO) and neodymium:YAG (Nd:YAG) laser capsulotomy after implantation of 3 intraocular lens types (IOLs).

SETTING

Storm Eye Institute, Medical University of South Carolina, Charleston, South Carolina, USA.

METHODS

This retrospective chart review comprised eyes having uneventful phacoemulsification and implantation of 1 of 3 AcrySof IOLs: ReSTOR SN60D3 (multifocal spherical group), Natural SN60AT (monofocal spherical group), or IQ SN60WF (monofocal aspheric group). Eyes were matched by age, sex, and follow-up. The PCO rate, Nd:YAG capsulotomy rate, time from surgery to PCO diagnosis, and time from surgery to Nd:YAG capsulotomy were assessed.

RESULTS

Charts of 225 eyes (75 in each group) with a mean follow-up of 15.9 months +/- 6.5 (SD) were evaluated. The PCO rate was 42.7% in the multifocal spherical group, 28.0% in the monofocal spherical group, and 14.7% in the monofocal aspheric group. The Nd:YAG capsulotomy rate was 25.3%, 17.3%, and 4.0%, respectively. The difference in the Nd:YAG rate was statistically significantly higher in the multifocal and monofocal spherical groups than in the monofocal aspheric group (P<.001 and P<.008, respectively) but was not significantly different between the 2 spherical IOL groups (P = .232). The time from surgery to PCO documentation was not significantly different between the 3 groups.

CONCLUSIONS

Intraocular lens configuration may have contributed to the difference in the PCO rate between the 2 spherical IOLs and the aspheric IOL. Based on the Nd:YAG rate as an indicator for visual significance, PCO may be less visually significant in eyes with the aspheric IOL than in eyes with 1 of the spherical IOLs.
