Purpose To evaluate the 24-month outcomes of lens extraction combined with circumferential, 360-degree trabeculotomy in patients with progressive pigmentary glaucoma. Methods This prospective, interventional case series included 32 eyes of 32 patients with progressive pigmentary glaucoma. All patients underwent phacoemulsification combined with gonioscopy-assisted transluminal trabeculotomy (GATT). Outcome measures included intraocular pressure (IOP), number of glaucoma medications, and success rates at 24 months. Qualified success was defined as IOP <= 18 mm Hg with a 20% IOP reduction from baseline, without requiring further glaucoma surgery. Results The mean preoperative IOP was 21.4 (SD 6.3) mm Hg on a mean of 2.2 (SD 1.5) glaucoma medications. At 24 months, mean IOP was reduced to 13.0 (SD 3.5) mm Hg (a 39% reduction), and mean medication use was reduced to 0.8 (SD 1.0). The Kaplan-Meier estimated probability of qualified success at 24 months was 75.0% (95% CI: 61.4% -91.6%). Conclusion Combined lens extraction and GATT effectively lowers IOP and medication use in pigmentary glaucoma. By targeting the source of pigment dispersion, lens extraction may halt the disease process, making this a very promising strategy.
