Krypton laser trabeculoplasty. A clinical report
R. C. Spurny and C. M. Lederer Jr
Krypton red (647.1 nm) or krypton yellow (568.2 nm) laser trabeculoplasty
was performed in 15 phakic eyes of 14 patients. After an average follow-up
of five months, these patients had an average drop of intraocular pressure
of 8.9 mm Hg. In addition, in eight of these patients studied, argon laser
trabeculoplasty was performed in the opposite eye. After an average
follow-up of more than five months in these eight patients, the average
drop of IOP was 7.2 mm Hg in the eyes with krypton laser trabeculoplasty
and 6.8 mm Hg in the eyes with argon laser trabeculoplasty. This
preliminary study indicates that laser trabeculoplasty may be effectively
performed with krypton wavelengths.
