PURPOSE: Our study investigates whether preoperative anterior chamber depth (ACD) measured by Scheimpflug tomography could serve as a potential predictor of graft failure in eyes undergoing Descemet stripping endothelial keratoplasty (DSEK).
METHODS: A retrospective review was conducted on patients who underwent primary or repeat DSEK between January 2020 and August 2021 at Bascom Palmer Eye Institute. Charts from 378 primary and 192 repeat DSEK patients were reviewed and ultimately 47 primary and 21 repeat DSEK patients met criteria for inclusion. Data collection included demographics, preoperative ACD, best-corrected visual acuity, and length of follow-up.
RESULTS: Demographics were similar between groups, and there was no significant difference in the average best-corrected visual acuity between the single and repeat DSEK groups preoperatively. Baseline preoperative ACD was greatest in the single DSEK group (3.51 ± 0.90 mm) when compared to baseline preoperative ACD in the repeat DSEK group (3.01 ± 0.67 mm, P = 0.003). The preoperative mean ACD was smallest in the repeat DSEK group before the second DSEK (2.94 ± 0.48 mm, P = 0.001). Preoperative baseline ACD was the only variable to affect graft survival time significantly ( P = 0.012). The incidence of glaucoma diagnosis was similar in both groups (42.5% vs. 42.8%, P = 0.471). The diagnosis of glaucoma and presence of incisional glaucoma surgery did not affect the graft survival time ( P = 0.129, P = 0.559) or need for repeat DSEK.
CONCLUSIONS: Smaller baseline preoperative Scheimpflug ACD measurement may be a possible predictor of the need for repeat DSEK. Our study found that Scheimpflug ACD decreases with subsequent DSEK failure.
