To Evaluate Corneal Biomechanical Changes after Strabismus Surgery with Ocular Response Analyzer

INTRODUCTION: Corneal biomechanical changes were also suspected and investigated after some scleral procedures but not after strabismus surgery. In this study we aimed to evaluate corneal biomechanical changes following strabismus procedures.with ocular responce analyser.

METHODS: Methods: This study a retrospective case series. Corneal biomechanical properties were assessed using the Ocular Response Analyzer (ORA, Reichert Inc., Depew, New York, USA) before, and 6 months after the surgery in 67 eyes of 67 patients performing strabismus surgery. Preoperative and postoperative changes in corneal hysteresis (CH) and corneal resistance factor (CRF) outcomes were examined.

RESULTS: Results: In the study group were divided Group1 and Group2 for the performed surgery. Preoperative and postoperative CRF were showed statistically significant differences in Group 1 and Group 2. In Group 1 at preoperative the mean CH was 11.7 ± 2.4 mmHg and 12.3 ± 2.5 mmHg at postoperative. The differences were not statistically significant in Group1.

DISCUSSION AND CONCLUSION: This is the first study aimed at evaluating the corneal biomechanical changes after strabismus surgery. and CRF were found to statistically significance at 6 month after strabismus surgery.
