| Abstract |
|
To evaluate the abnormal positions of intraocular lens after cataract extraction and intraocular lens implantation, the study used the image analysis technique. Tilting and decent ration of posterior chamber intraocular lens(PCL) were studied according to the anterior capsulotomy. 103 patients(120 eyes) were randomized into 6 groups(20 eyes each) according to posterior chamber lens style and anterior capsulotomy type, and measured the degrees of tilting and decent ration of PCL by Scheimpflug camera. Three piece PCL implantation group showed significant less tilting than one piece PCL implantation group at postoperative 1 week. In one radial tear of anterior capsulotomy group, three piece PCL showed less tilting than one piece PCL. At postoperative 2 months, continuous curvilinear capsulorhexis without radial tear group showed significant less decent ration and tilting than one radial tear group. At postoperative 1 week and 2 months tilting of the continuous curvilinear capsulorhexis group was less than two or more radial tears group. As time passes from 1 week to 2 months tilting decreased significantly, but decentration did not showed significant decrease. |
