Abstract

PURPOSE
To evaluate the postoperative refractive error after vitrectomy and gas tamponade in macular hole patients. METHODS: Thirty patients with full-thickness macular hole were enrolled in this study. Thirty eyes had vitrectomy, internal limiting membrane peeling, and gas tamponade. Preoperative and postoperative refractive errors were compared. Five eyes also had cataract extraction and implantation of an IOL and actual and expected refractive errors were compared. RESULTS: The refraction after vitrectomy and gas tamponade shifted toward myopia by 0.71 diopter compared with preoperative refraction. The actual refractive errors in cataract surgery group shifted toward myopia by 0.65 diopter. CONCLUSIONS: . Use of a gas tamponade in macular hole patients is thought to have induced the myopic change by pressing the crystalline lens forward.
