Abstract

Purpose: : To examine corneal hysteresis in patients after LASIK

Methods: : At least four measures with the Ocular Response Analyzer (ORA) to evaluated corneal hysteresis in patients with LASIK surgery.

Results: : 48 eyes of 24 patients after LASIK, mean age was 33 years (range, 24-40). Eighteen of 24 (75%) were female. Mean corneal hysteresis was 7.67 (4.4-18.3), other values were corneal resistance 7.89, mean Goldmann-correlated IOP 14.85 mmHg, mean corneal-compesated IOP 18.37 mmHg, mean CCT was 471.25 µm. The results were compared with 66 eyes of 33 normal subjects, mean age was 33 years (range, 21-59). Nineteen of 33 (57.57%) were female. Mean corneal hysteresis was 8.97 (3.9-14.1), other values were corneal resistance 8.75, mean Goldmann-correlated IOP 17.59 mmHg, mean corneal-compesated IOP 19.33 mmHg, mean CCT was 549.92 µm. The were statistically significant differences in corneal hysteresis.

Conclusions: : There are significant differences in corneal hysteresis between normal subjects and patients with LASIK surgery.
