Abstract:
PURPOSE: To compare the actual and expected refractive errors of intraocular lens (IOL) implantation with vitrectomy in various conditions. METHODS: One hundred sixty-five eyes were divided into five groups: Group 1 had cataract extarction and IOL implantation only, Group 2 had cataract extraction and IOL implantion after vitrectomy, Group 3 had cataract extraction and implantation of an IOL with vitrectomy, Group 4 had cataract extraction and IOL implantaion with vitectomy and scleral encircling, and Group 5 had cataract extraction and IOL implantaion with vitrectomy and intraocular gas injection. The actual and expected refractive errors of IOL implantation were compared. RESULTS: Mean myopic shift was 0.15 diopter for group 1, 0.22 diopter for group 2, 0.20 diopter for group 3, 1.40 diopter for group 4, 0.91 diopter for group 5. CONCLUSIONS: Vitrectomy alone has no influence on refractive error but when scleral encircling or intraocular gas injection were performed with vitectomy, there were statistically significant myopic shifts.
