Abstract
Cataract surgery has progressed from a basic operation to correcting all refractive problems in addition to removing the clouded crystalline lens. allowing for a complete restoration of vision with high degrees of spectacle independence. Astigmatism is a meridian-dependent refractive defect that affects the majority of people's eyes.Some studies have shown that 30%, 22% and 8% of patients with cataract have more than 0.75 diopters (D), 1.50 D and 2.00 D of corneal astigmatism, respectively. In the current phacoemulsification era, the most frequent approach for treating pre-existing corneal astigmatism is to implant toric intraocular lenses (IOLs). Optical biometry has shown to be more accurate and safer than ultrasonic biometry for biometric measurement of the eye. As a result, optical biometry has grown increasingly popular. Among them, is IOL Master 700 based on SS-OCT which has of measuring the Total Keratometry (the anterior and posterior surfaces of the cornea). Aim of the work: The aim of the work was to compare the standard keratometry to total keratometry in toric intraocular lens calculation by a swept source optical coherence tomography biometer.
