Abstract

Purpose: To compare reduction of intraocular pressure (IOP) after Trabectome in pseudophakic patients and Trabectome combined with phacoemulsification (Trabectome-phaco) in phakic patients. Methods: Cases were excluded if patients were followed for less than 12 months, diagnosed with neovascular glaucoma, or required additional glaucoma surgery within 12 months after Trabectome or Trabectome-phaco. Missing data such as type of glaucoma, gender, or age was imputed by generating 5 similar but non-identical datasets. Groups were matched using Coarsened Exact Matching based on age, gender, type of glaucoma, race, preoperative number of glaucoma medications and baseline IOP. Linear regression was used to examine IOP reduction after surgery. Results: A total of 612 cases were included in the study with 248 Trabectome cases and 364 Trabectome-phaco cases. Baseline IOP was found to be statistically significant. An average of 0.73±0.03 mmHg IOP reduction is associated with an increment of 1 mmHg in baseline IOP. Type of surgery was not statistically significant after adjusting for baseline IOP, age, baseline number of glaucoma medications and type of glaucoma. Conclusion: Patients with higher baseline IOP are expected to have a greater IOP reduction.
