IOL Power Calculation in Patients with Lasik

Abstract:

Purpose: To make a more accurate calculation IOL (intraocular lens implantation) power in patients with refractive surgery (LASIK). To make a comparison between the preoperative and postoperative IOL power calculation and compare it with corrected refractive defect. Methods: Thirty patients who underwent LASIK no matter age, gender o refractive defect were included. IOL power calculation was made with 5 different formulas (hoffer, holladay, binkhorst II, SRK II and SRK T) and with 3 different types of keratometric values (optic and topographic keratometries and corneal power by topography) the topographer used was the Humprey Atlas. Thirty calculations were made for each eye with Alcon Ocuscan biometer, patients underwent LASIK with Visx S2 and Chiron Technolas 217 using Hansatome microkeratome. The difference between the preoperative and postoperative IOL calculation was made and compared …
