ABSTRACT

PURPOSE:

To analyze the effect of scleral lens application for preventing corneal edema during vitrectomy on postoperative corneal status using anterior segment OCT (RTVue 100, Optovue, Fremont, CA, USA).

METHODS:

The medical records of 42 eyes (42 patients) who underwent total vitrectomy with no appreciable corneal disease between November 2014 and June 2015 were retrospectively reviewed. Evaluations were performed at 1 day, 1 week, and 1 month after total vitrectomy. Corneal status was noted at every follow-up visit using anterior segment OCT. An analysis was performed to define the changes in corneal status in association with scleral lens application during the surgery.

RESULTS:

18 of 42 eyes were treated with a scleral lens during total vitrectomy. The corneal thickness increased after vitrectomy in all cases. The mean corneal thickness increment was 23.9 ± 9.7 µm in the scleral lens group and 43.0 ± 19.5 µm in the non-scleral lens group at 1 day after vitrectomy (p < 0.001). At 1 week after vitrectomy, the mean corneal thickness increment was 8.1 ± 7.2 µm in the scleral lens group and 32.3 ± 19.2 µm in the non-scleral lens group (p < 0.001). The difference in superficial punctate keratitis grade between the two groups was not statistically significant.

CONCLUSION:

Scleral lens application during vitrectomy seems to prevent postoperative corneal edema. More cases and a longer period of study is needed to draw definitive conclusions.
