We treated 20 eyes of glaucoma after penetrating keratoplasty by transscleral diode laser cyclo-photocoagulation. All the eyes had failed to achieve control of intraocular pressure (IOP) by medication. We used a diode laser with 800 nm in wavelength, 2 seconds each for exposure, power output from 500 to 2,000 mW, and 10 to 40 exposures per session. After follow-up for 15 to 265 weeks averaging 103 weeks, the aver-age IOP decreased to 23mmHg from pretreatment level of 39mmHg. IOP decreased in 19 eyes with medica-tion. IOP decreased below 21mmHg in 13 eyes (65%) without medication, including 7 eyes which attained IOP control after a single session. Loss of light perception occurred in 2 eyes and vitreous hemorrhage in 1 eye. The donor cornea was initially transparent in 14 eyes. It became opaque in 6 eyes after treatment. The findings show that transscleral diode laser cyclophotocoagulation is relatively safe and effective for refractory glaucoma after penetrating keratoplasty.
