* OBJECTIVE: To present a method for remodeling oversized blebs using the THC: YAG laser and describe its use in treating hypotony and bleb leaks. * METHODS: Retrospective medical record review of 13 patients who underwent holmium laser bleb revision. * RESULTS: Thirteen eyes of 13 patients were analyzed. All the patients had an oversized bleb and 2 patients presented an associated late-onset leaking bleb. Mean preoperative IOP was 4.1 mm Hg. THCYAG laser energy was applied to the bleb to remodel and/or close the leak. After a mean follow up of 17.3 months, the mean IOP was 7.84 mm Hg ± 2.3. Postsurgery complications included hyphema and the inadvertent rupture of a conjunctival microcyst. Visual acuity improved in 9 of the eyes and remained stable in 4 of the eyes. * CONCLUSION: The THCYAG laser can be used effectively to sculpt large blebs, reduce symptoms associated with large blebs, increase IOP in hypotonous eyes, and under specific circumstances, close bleb leaks.
