PURPOSE: To assess the outcomes of micropulse transscleral cyclophotocoagulation for intraocular pressure (IOP) control in keratoplasty eyes. METHODS: Outcomes of micropulse laser treatments of postkeratoplasty eyes were retrospectively reviewed. IOP was assessed with applanation tonometry. Keratoplasty survival was calculated with Kaplan-Meier survival analysis. RESULTS: Sixty-one eyes in 57 patients received laser treatment; 31 eyes received 1, 21 received 2, 8 received 3, and 1 received 4 treatments. The median follow-up was 21 months (range, 2-35 months). At baseline, the mean IOP was 28 ± 11 mm Hg. At 1, 3, 6, and 12 months after the last treatment, respectively, the numbers of eyes with IOP data were 58, 50, 46, and 38; the mean IOP was 17 ± 7, 17 ± 8, 18 ± 9, and 15 ± 5 mm Hg; the proportions of eyes with IOP ≤ 15 mm Hg were 40%, 51%, 48%, and 55%; and the proportions with IOP ≤ 12 mm Hg were 21%, 29%, 20% and 29%. Six eyes (10%) received subsequent glaucoma filtration surgery. The mean number of antiglaucoma medications used before the initial treatment was 2.7 (range, 0-4) versus 2.2 (range, 0-4) at last follow-up. At baseline, 7 grafts were decompensated and 5 of 54 clear grafts (9%) had endothelial cell density < 700 cells/mm. Graft survival was 94% at 1 year and 81% at 2 years after the initial laser treatment. CONCLUSIONS: Micropulse transscleral cyclophotocoagulation is a noninvasive alternative to glaucoma filtration surgery for IOP reduction in keratoplasty eyes.
