CORRELATION OF PREOPERATIVE IOL POWER WITH THE POSTOPERATIVE REFRACTIVE STATUS IN SENILE CATARACT.
Journal Title: International Journal of Advanced Research (IJAR) - Year 2018, Vol 6, Issue 7
Abstract
Aim of study-To correlate preoperative IOL power and postoperative refractive status in patients operated for senile cataract admitted to department of Ophthalmology in a tertiary health care centre MATERIAL AND METHODS This is a hospital based prospective observational study was done for 2 year in 110 patients. All cases of senile cataract without systemic /other ocular diseases admitted for cataract surgery are included in this study. Traumatic cataract and complicated cataract, Senile cataract with systemic or associated complications, All cases congenital and developmental cataract, Cases with intra or postoperative complications, Cases of axial length <21mm or >25mm were excluded from the study. In all the patients IOL power calculated using A scan and biometry (SRK–II) and cataract extraction done by manual SICS with PMMA IOL implantation by a single surgeon. Refractive status evaluated at 6 weeks postoperatively in all patients. RESULTS From our study it is concluded that Post-operative myopic (66%) is more common than hypermetropic shift (31%), with Most of the postoperative error is within ±1.5D. Visual acuity varied from 6/6 -28.6%, 6/9-41.6%, 6/12-20%, 6/18-10% at 6 weeks postoperatively Refractive error varied between ± 1.5D Spherical with ±1.5D Cylindrical with or without the rule Cylindrical error was common postoperatively. CONCLUSION In spite of exclusion of associated systemic and ocular diseases, Proper preoperative evaluation of IOL power is necessary and important tool for better post-operative refractive status.
