Abstract Details

Purpose:

To evaluate the risk factors and the incidence of Nd: YAG posterior capsulotomy due to posterior capsular opacification in adult cataract patients whom are under 50 years old by different age groups.

Setting:

Department of Ophthalmology, The Catholic University of Korea Uijeongbu St. Mary’s Hospital, Korea Between October 2006 and June 2012

Methods:

We retrospectively studied on 280 eyes that received phacoemulsification and intraocular lens implantation. Total observation period was 26.2 months on average. We divided subjects into three different age groups - 20's, 30's and 40's to evaluate incidence of posterior capsulotomy. And investigated risk factors based on gender, age, type of cataract, type of intraocular lens(IOLs), axial length, existence of diabetic mellitus, history of ocular trauma, atopic dermatitis and refractive surgery using statistical analysis.

Results:

The incidence of posterior capsulotomy was 13.9% (39 of 280 eyes) and there is no statistical significant differences by age(7.7% of 20s, 13.8% of 30s and 14.4% of 40s, p=0.595). We divided subjects into three different groups by axial length - below 22 mm, 22 to 26 mm, over 26 mm and posterior capsulotomy were done 0/2(0%), 12/166(7.2%), 27/112(24.1%) accordingly, which implied the longer axial length showed statistically significant increase in the incidence of posterior capsulotomy(p=0.036). The incidence of posterior capsulotomy was higher in women than in men(p=0.006). Correlation between posterior capsulotomy and type of cataract, type of IOLs and existence of diabetic mellitus, history of ocular trauma, atopic dermatitis and refractive surgery were not statistically significant.

Conclusions:

The difference in the incidence of Nd: YAG laser posterior capsulotomy by age was not statistically significant in adult cataract patients whom are under 50 years old. We found out that longer axial length resulted higher risk of posterior capsulotomy.
