Corneal Incision vs. Toric Lens for Cataract Surgery Astigmatism

The study aims to compare two different methods used during cataract surgery to address astigmatism, a common issue where the eye does not focus light evenly on the retina. These methods include making small cuts on the edge of the cornea, known as limbal relaxing incisions (LRIs), and using a special type of lens called a toric intraocular lens (IOL). The focus is on understanding which of these techniques is more beneficial for patients who have astigmatism before surgery, helping them achieve better vision outcomes. Participants will undergo cataract surgery using one of the two methods. Those receiving LRIs will have small incisions made on the cornea to reshape it, while others will have a toric IOL implanted to correct the astigmatism. The study will evaluate how well each method corrects the patient's vision and reduces astigmatism. The results will help determine the most effective approach for improving vision quality in cataract patients with pre-existing astigmatism.
