Abstract

To compare the preoperative and postoperative anterior chamber depths in cataract surgery, we performed phacoemulsification followed by posterior chamber intraocular lens(PCIOLs) implantation on 20 eyes(Group I) and planned extracapsular cataract extraction(p-ECCE) followed by PCIOLs implantation on 20 eyes(Group II). After that, we measured prospectively the preoperative anterior chamber (AC) depths and postoperative AC depths 1, 3, 7, 30 and 60 days by using a Scheimpflug camera. The preoperative mean values of AC depths were 2.93mm in Group I and 2.71mm in Group II. In Group I, the postoperative AC depth was increased significantly compared to preoperative AC depth and the difference between preoperative and postoperative AC depth was maintained from the first day of measurement to day 60(p<0.001). In Group II, AC depth of the postoperative day 1 was significantly increased compared to the preoperative depth(p<0.001), but it was slightly decreased at postoperative day 30(p=0.002) and day 60(p=0.02). And there were no significant differences between Group I and Group II in changed of AC depth. The result implies that AC depth was increased significantly after both phacoemulsification and p-ECCE.
