Summary

Cataract is a leading cause of blindness in the world. Cataract surgery is one of the most commonly performed ocular procedures. We aim to compare the newer generation biometry formula; the Kane formula with the commonly used SRK-T formula for intraocular power calculation in uneventful phacoemulsification surgery to assess the post-operative refractive outcomes at one month post-surgery.

Detailed description

Purpose: To compare post-operative refractive outcome with Sanders Retzlaff Kraff theoretical (SRK T) and Kane formulae for intraocular lens (IOL) power calculation in cataract patients Study Design: Prospective, interventional study Place and Duration of Study: Department of Ophthalmology, Fauji Foundation Hospital, Rawalpindi Material and Methods: A total of a 70 eyes, 35 in each group will be included in our study. The patients will be randomly divided into two groups. In cases of bilateral cataract, one eye will be included in each group for better control. IOL power calculation in Group A will be done with the SRK-T formula and in group 2 with the Kane Formula. Autokeratometry and A-scan ultrasound will be done for biometry. Inclusion criteria will be uncomplicated cataract in both genders. Exclusion criteria will be ocular trauma, uveitis, previous intraocular surgery, or any retinopathy. All patients will undergo phacoemulsification with foldable lens implantation by two experienced surgeons. Post-operative refractive outcome will be evaluated at one month after surgery. The two groups will be compared. Results: The results will be calculated by SPSS. Conclusion: A conclusion will be drawn on the basis of our results.
