Therapeutic effect of suture-fixation of intraocular lens for non-normal lens eye

Abstract:

To observe the clinical therapeutic effect of suture-fixation of intraocular lens (IOL) for non-normal lens eye of non-posterior capsule because of all kinds of reasons . METHODS:Alcon CZ70BD IOL was selected. 8 cases (9 eyes) of non-normal lens (including 3 eyes of hypermature cataract, 4 eyes of traumatic cataract with subluxation, 2 eyes of Marfans syndrome ) were treated with suture-fixation of IOL because of non-posterior capsule or disintegrated-posterior capsule; 8 cases (8 eyes) of non-normal lens that had been treated with cataract surgery (including 7 aphakic eyes with pupillary complications, 1 eye of dislocated IOL) were treated with secondary suture-fixation of IOL. Main outcome measures were visual acuity and complications. All the patients were followedup for 1-6 months. RESULTS: Mild anterior chamber or vitreous hemorrhage occurred in 5 eyes（29%） intraoperatively or postoperatively and cured in 10 days. Choroidal detachment was observed in 1 eye （6%） and cured in 1 month. Ocular hypotension because of mild incision leakage occurred in 2 eyes（12%） postoperatively and cured by hypertension bandaging in 5 days. Uncorrected visual acuity ＞0.1 was achieved in 13 eyes (76%) at the first day and 17 eyes (100%) at the 10^th day; Uncorrected visual acuity ＞0.3 was achieved in 11 eyes (65%) and 12 eyes (71%) at the 10^th day and 1st month. CONCLUSION:Suture-fixation of IOL is a good choice for non-normal lens eye of non-posterior capsule.
