Abstract

Background

To evaluate the effects of Nd : YAG Laser posterior capsulotomy, I performed posterior capsulotomy on after cataract(72 eyes) by using Q-switched Nd:YAG laser from March 1994 to August 1995.

Results

The results were as follows;

1) 24 aphakic eyes(33.3%), 45 ECCE with PCL inserted pseudophakic eyes(62.5%), 3 KPE with PCL inserted pseudophakic eyes(4.2%) were followed.

2) On performing posterior capsulotomy, the power setting of Nd:YAG laser was ranged from 2.0 to 2.9mJ(62.5%), more than 40 pulses were used in 35 eyes(48.6%).

3) Postoperative visual acuity was improved in 68 eyes(94.4%) and 0.5 or better in 47 eyes(65.3%)

4) Ocular complications after posterior capsulotomy were transient increase of intraocular pressure(8.3%), sustained increased intraocular pressure(4.2%), anterior uvetis(2.8%), vitreous prolapse(2.8%), corneal damage(2.8%), intraocular lens damage(1.4%), cystoid macular edema(1.4%), retinal detachment(1.4%).

Conclusion

As the results, posterior capsulotomy with the Nd : YAG laser offers several advantages over primary or secondary surgical capsulotomy and has fewer complications.
