Comparison of refractive error in eyes with vitrectomy, silicone oil tamponade finished phacoemulsification and intraocular lens implantation in different time point

Abstract

AIM: To compare the refractive error in eyes with vitrectomy and silicone oil tamponade finished phacoemulsification and intraocular lens(IOL)implantation in different time point. METHODS: Fifty-one patients(51 eyes)with vitrectomy and silicone oil tamponade performed phacoemulsification and IOL implantation were retrospectively analysed during 2009-01/2011-12 and divided into three groups by different time point of phacoemulsification and IOL implantation. There were 17 cases in A group performed silicone oil tamponade after vitrectomy combined with phacoemulsification and intraocular lens IOL implantation, silicone oil removal was performed after 3-6 months; 13 cases in B group performed silicone oil removal combined with phacoemulsification and IOL implantation; 21 cases in C group of scheduled phacoemulsification and IOL implantation after silicone oil removal, refractive error was compared 3months postoperatively. RESULTS: The average absolute value of refractive error was 0.873±0.256D in A group, 0.828±0.134D in B group, 0.473±0.121D in C group. There was no statistical significant difference compared with A group and B group(P>0.05), but there was statistical significant difference compared with C group and A, B group(PCONCLUSION: Axial length was measured by A Scan ultrasonograph. The refractive error was small in group of phacoemulsification and IOL implantation after silicone oil removal relatively.
