Abstract

Background: In eyes with significant hyperopia, where attaining precise surgical refractive outcomes may be particularly problematic, the predictive efficiency of the formulas falls. Aim of work: The goals of this research were: (1) To determine how well the individual can see after having cataract operation in hyperopic persons utilizing the IOL master (Carl Zeiss Meditec, Inc., Dublin, CA, USA) & the Topcon RM-8000B, and (2) To contrast the prediction error of two biometric equations (Hoffer Q and SRK/T). Methods: Our study was an observational clinical study (analytical cross-sectional). 180 eyes from 180 patients of both sexes with axial length below 22 mm were recognized from individuals performing cataract surgery by phacoemulsification at Ophthalmology Department, Faculty of Medicine, Suez Canal University. A sample of cases was chosen & divided into two groups, each including 90 eyes. One group used Hoffer Q formula (n= 90) and the other group used SRK/T formula (n= 90). Biometry was performed on all participants utilizing the intraocular lens (IOL) master. Each participant had one of their eyes chosen at random. Errors in prediction were computed by comparing preoperative refraction with the refraction measured after surgery utilizing the improved formulae (Hoffer and SRK/T). Results: Our findings also revealed that the Hoffer Q formula is not with greater precision than SRK/T formula in refractive outcome in hypermetropic patients undergoing cataract surgery as there was no significant variation among them in refractive outcome. Conclusion: Hoffer Q formula is not superior in terms of accuracy to SRK/T formula in refractive outcome in hypermetropic patients undergoing cataract surgery as there was no significant distinction among them in refractive outcome.
