Abstract
Purpose
The changes in anterior chamber depth (ACD) and refractive error in pseudophakia with 6 types of intraocular lenses (IOLs) after cataract surgery were compared in the present study.
Methods
The medical records of 108 eyes (73 patients) who underwent cataract surgery with 6 types of IOLs, 5 types of single-piece IOLs and 1 type of 3-piece IOLs between March 2007 and April 2010 were retrospectively reviewed. ACD and refractive error were measured preoperatively, and at 1 day, 1 week, 1 month and 3 months postoperatively and the data were extracted and analyzed.
Results
In the case of the SN60WF lens, the ACD was significantly shallow as compared to other IOLs at each follow-up period and refractive error was significantly myopic at 3 months postoperatively. In the case of SN60WF and ZA9003 lenses, the ACD was significantly changed at 3 months postoperatively from 1 day postoperatively. In the case of the MI60 lens, refractive error was slightly hyperopic, but not statistically significant.
