Abstract Details

Purpose:

The aim of the study is to investigate the effect of Nd:YAG laser capsulotomy on visual acuity(VA), refraction, keratometry, central corneal thickness(CCT), anterior chamber depth(ACD), anterior chamber volume(ACV), anterior chamber angle(ACA) in patients with posterior capsule opacification(PCO) and also to compare the IOL haptic design on anterior segment parameters with single-piece and three-piece hydrophobic acrylic material.

Setting:

Prospective case control study

Methods:

All of the pseudophakic subjects were controlled according to the hospital records and divided into two groups according to the IOL haptic design as single piece and three piece hydrophobic acrylic type. Group 1 consist of 35 subjects with single-piece IOL and group 2 consist of 30 subjects with three-piece IOL. Measurements with the Sirius topographer were performed for anterior segment analysis. Data for the posterior cornea, anterior lens, anterior chamber, anterior chamber angle and iris are obtained from Scheimpflug images These examinations and were performed before, one week and one month after Nd:YAG laser capsulotomy.

Results:

Mean age was 72.3 ± 5.2 years (range: 61–80) in group 1 and 72.3 ± 6.8 years (range: 59–83) in group 2. Cylindrical error changes were significant between groups and hyperopic shift seen in single piece group(P=0,041). Anterior chamber depth, anterior chamber volume and anterior chamber angle changes significant between groups(p<0,05).

Conclusions:

Anterior segment changes after the Nd:YAG laser capsulotomy are important for the understanding the ocular dynamics according the IOL haptic design.
