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.
