Abstract Details

Purpose:

To investigate the effects of relaxing anterior capsulotomy in capsular phimosis after cataract surgery.

Setting:

Seoul Metropolitan Government-Seoul National University Boramae Medical Center/South Korea

Methods:

A total of 29 eyes of 26 patients who had relaxing anterior capsulotomy in capsular phimosis after uneventful cataract surgery were included. Uncorrected (UCVA) and best corrected visual acuity (BCVA), refractive changes of spherical equivalent (SE), and changes of anterior chamber depth (ACD) measured by optical biometer (IOLMaster500), ultrasound biomicroscope (UBM), endothelial cell count (ECC), intraocular pressure (IOP) were measured before and 1 month after the laser treatment.

Results:

Before treatment, 16 eyes (55.17%) showed hyperopic shift, 10 eyes (34.48%) showed myopic shift and 3 eyes (10.34%) stayed unchanged SE after cataract surgery. The UCVA and BCVA improved significantly (P<0.001, P<0.001) after anterior relaxing capsulotomy. ACD measured by IOLMaster (-0.23mm) and UBM (-0.20mm) changed significantly (P<0.001, both). ACD changes correlates with the changes of SE (Rho=0.74, P=0.021). The mean ECC change was 22.95±193 cells/mm2 (P=0.528).

Conclusions:

Capsular phimosis can result hyperopic and myopic shift after cataract surgery. Relaxing anterior capsulotomy using Nd:YAG laser improve visual acuity and significantly changes the ACD, and refraction. Refractive changes after the treatment can be attributable due to the changes of ACD.
