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.
CONCLUSIONS
There was difference in ACD changes after cataract surgery associated with various IOLs, which affected the postoperative refractive errors.

  Figure 1. The postoperative mean anterior chamber depth (ACD) in 6 types of IOL. In the SN60W F, the ACD is significantly shallow as compared to other IOLs at each follow-up period.

  Figure 2. The postoperative differences of mean anterior chamber depth after cataract surgery. In the SN60W F and ZA9003, there is significant change in ACD at 3 months postoperatively from 1 day postoperatively.

• 

  Figure 3. The postoperative refractive error (mean spherical equivalent differences) between the target refraction and the actual refraction at each period. In the SN60W F, refractive error is significantly myopic at 3 months postoperativlely. In the MI60, refractive error is slightly hyperopic, but not statistically significant.
