Abstract

PURPOSE
To evaluate changes in corneal keratometry, high-order aberrations (HOAs), and anterior chamber parameters after trabeculectomy using Pentacam(R) (Oculus Inc., Dutenhofen, Germany). METHODS: Forty eyes of 40 patients who underwent limbal-based trabeculectomy or fornix-based trabeculectomy between July 2011 and May 2012 were retrospectively reviewed. Intraocular pressure (IOP), corneal keratometry, central corneal thickness, anterior chamber depth, anterior chamber volume, and HOAs were measured using Pentacam(R) preoperatively and at 3 months postoperatively. RESULTS: The mean age of patients who underwent trabeculectomy was 58.26 +/- 16.28 years. IOP showed significant decrease after surgery in both groups compared to preoperative values (p < 0.05). There were no significant differences in corneal keratometry, anterior chamber depth, anterior chamber volume, central corneal thickness, total root mean square (RMS), trefoil, and coma after surgery (p > 0.05). CONCLUSIONS: Postoperative corneal keratometry and anterior chamber parameters did not change significantly compared to preoperative values in glaucoma patients after performing trabeculectomy. Most HOAs that affected quality of vision were not changed in the limbal-based trabeculectomy or fornix-based trabeculectomy.
