Clinical Results of Q-Switchd Nd: YAG Laser Posterior Capsulotomy

ABSTRACT

From February 1987 to January 1991, We performed posterior capsulotomy on after cataract patients(400 eyes)by using Q-Switched Nd: YAG Laser. The results were as follow; 1. 226 aphakic eyes and 174 pseudophakic eyes(22 anterior chamber IOLs, 152 posterior chamber IOLs) were followed. 2. 335 adult and senile cataracts, 47 traumatic cataracts, and 18 congenital cataracts were followed. 3. The power setting of Nd: YAG Laser ranged from 1.0 to 2.4 mJ in 261 eyes(65.3%); less than 40 pulses were used in 298 eyes(74.5%). 4. Postoperative corrected visual acuity of 0.7 or better was achieved in 207 eyes(51.8%) and 1.0 or better in 112 eyes(28%). 5. Frequent ocular complications were a transient increase of intraocular pressure(15.8%) and vitreous prolapse(l3.5%).
