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

Özet

Objectives: 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 proce-dures with ocular response analyzer. Methods: This study was a retrospective case series. Corneal biomechanical properties were assessed using the ocular response analyzer (ORA) (ORA, Reichert Inc., Depew, New York, USA) before and 6 months after the surgery in 67 eyes of 67 patients performing strabismus surgery. Pre- and post-operative changes in corneal hysteresis (CH) and corneal resistance factor (CRF) outcomes were examined. Results: The study group were divided into Groups 1 and 2 for the performed surgery. Pre- and post-operative CRFs were showed statistically significant differences in Groups 1 and 2. In Group 1, the mean CH was 11.7±2.4 mmHg at pre-operative and 12.3±2.5 mmHg at postoperative. The differences were not statistically significant in Group 1. Conclusion: This is the first study aimed to evaluate the corneal biomechanical changes after strabismus surgery. and CRF were found to statistically significance at 6 month after strabismus surgery.
