Two scleral flaps with limbal incisions and two peripheral iridectomies were made at 1 o' clock and 7 o' clock positions respectively. A suture-leading needle was used to lead the prolene suture from the limbal incision and iridectomy on one side through the iridectomy and limbal incision on the other side. Intraocular lens (IOL) was then fixed in the ciliary sulcus. Results: After a mean follow-up of 6. 6 months (range from 3 to 14 months), corrected visual acuity of 16 cases (16 eyes,66. 7% ) got 0.5 or better. Postoperative complications included discoria (4 eyes) , surface membrane formation ( 1 eye ), choroidal detachment (1 eye) and tilt of IOL (1 eyes),but all were not severe.

The surgically induced astigmatism in qualitative group two weeks after the operation was 3. 5 ± 1. 70 D and that in quantitative group was 2. 56±1. 60 D. There were 55.17% and 38. 24% of the eyes with over 2. 00 D corneal astigmatism in qu...展开更多
