An intraocular lens (IOL) is an artificial lens surgically implanted to replace the cloudy lens (lens) of the eye caused by cataracts. Toric lenses play a crucial role in cataract surgery. With new technological advancements, a wide variety of intraocular lenses (IOLs) have become available. Cataract surgery aims to correct not only distance vision but also near vision and astigmatism. This is made possible by newer types of lenses. If the patient has regular astigmatic vision problems related to the cornea, toric intraocular lenses can be used during cataract surgery to correct their astigmatism.
In practice, highly successful results are achieved for astigmatism up to 6-7 degrees. A key point to consider with toric lenses is the rotation problem, which is crucial for the success of the surgery. Therefore, it is extremely important that toric lenses are placed in the correct axis by experienced surgeons.
