Abstract
Purpose: To compare surgically induced corneal astigmatism following trabeculectomy versus deep sclerectomy and collagen implant (DSCI). Methods: 37 consecutive eyes of 28 patients having glaucoma surgeries for uncontrolled open-angle glaucoma were retrospectively analyzed. 16 eyes had trabeculectomy and 21 eyes had DSCI. Visual acuity, intraocular pressure (IOP) and autorefractokeratometry of both groups were evaluated preoperatively and 1, 7 days, 1, 3, 6, 12 months postoperatively. Postoperative changes in corneal astigmatism were evaluated using vector analysis. Results: Mean age was 51.63 ± 12.73 years in the trabeculectomy group and 39.95 ± 15.09 years in the DSCI group and differed between groups (p = 0.015). Visual acuity was significantly decreased after surgery compared with preoperative values and was improved slowly in both groups. Intraocular pressure was lower in the trabeculectomy group than in the DSCI group at postoperatively 1 and 6 months (p = 0.046 and 0.029, respectively). There was no significant difference in surgically induced corneal astigmatisms (SIA) between both surgeries, which decreased over time in the group with stable postoperative IOP. They showed with-the-rule astigmatism immediate postoperatively. The DSCI group with MMC showed less SIA than the group without MMC. Conclusions: Surgically induced astigmatisms following trabeculectomy and deep sclerectomy with collagen implant were not differ significantly between two surgeries.
