Abstract:
The postoperative results of 77 paients:(82 eyes) who had undergone phacoemulsification with implantation of oval optic poly methylmethacrylate (PMMA) introoular intraowlar lens (IOL) (5 X 6mm) were evaluated retrospectively. Scleral pocket incision was done tangentially at the point 2mm. apart from the surgical limbus and 5mm in length. No suture in the group 1 (30 eyes), single horizontal suture in the group 2 (31 eyes) and single X suture in the group 3 (21 eyes) were used for the closure method. Average uncorrected visual acuity at postoperative one week was 0.5 or better in each group and there was no statistically significant difference among three groups (p>0.05). The change in mean keratometric astigmatism from postoperative one to eight weeks turned out to be less than 1 diopter (D) in each group and there was no statistically significant difference among three groups (p>0.05). When the diameter of continuous cirular capsulorhexis (CCC) was greater than 5mm or the position of CCC was decentered, it was found that optic was partially escaped form the bag due to adhesion between the remained anterior and posterior capsular structure. It could be suggested that oval optic PMMA IOL showes early visual recovery with less astigmatism regardless of the suture method and in order to place the optic of IOL properly in the bag postoperatively, the diameter of CCC should be less than 5mm and the position of CCC should be centered.
