Narrative Responses:

Purpose
To evaluate changes in corneal keratometry, high-order aberrations (HOAs) and the anterior chamber parameters after trabeculectomy using Pentacam®.

Methods
Forty eyes of 40 patients who underwent limbal based trabeculectomy or fornix based trabeculectomy from July 2011 to May 2012 were retrospectively reviewed. Corneal keratometry, central corneal thickness, anterior chamber depth, anterior chamber volume, and higher-order aberrations were measured using Pentacam® preoperatively and at 3 months after surgery.

Results
The mean age of patients who underwent trabeculectomy was 58.26 ±16.28 years, respectively. IOP showed significant decrease after surgery in both groups compared to preoperative values. ( P < 0.050 ) There were no significant differences in corneal keratometry, anterior chamber depth, anterior chamber volume, central corneal thickness, total RMS, trefoil, and coma after both surgeries. ( P > 0.050 )

Conclusion
Postoperative corneal keratometry and anterior chamber parameters did not change significantly compared to preoperative values in glaucoma patients after performing trabeculectomy. Most of high-order aberrations that affected quality of vision were not change in the limbal based trabeculectomy and fornix based trabeculectomy.
