Abstract

Objective: The study aimed to evaluate the biometric and refractive changes after trabeculectomy with
mitomycin C ( MMC ) among patients with primary glaucoma.

Design: The study employed a prospective, observational design.
Materials and Methods: We recruited 24 patients with primary glaucoma, scheduled for trabeculectomy
with MMC. Best corrected visual acuity (BCVA), intraocular pressure (IOP), auto-refraction, keratometry,
anterior chamber depth (ACD) and axial length (AXL) were evaluated pre- and postoperatively at 2 weeks,
1, 3 and 6 months.

Results: BCVA, auto-refraction, keratometry (K1, K2) , AXL and ACD showed no significant change over
the course of the study, however postoperative mean IOP significantly decreased at 2weeks, 1, 3 and 6
months of the follow-up period when compared with the pre-operative IOP (p value <0.005), .
Conclusion: No significant difference was found regarding biometric and refractive changes after
trabeculectomy with MMC in patients with glaucoma .
