Limbal Relaxing Incisions (LRI)–Correction of Astigmatism–In cataract surgery, the most important problem that we are correcting is the clouding of the lens by removing it and placing a crystal clear intraocular lens implant (IOL). This takes away the vision loss caused by the cataract. The second most important part of the surgery is taking away significant nearsightedness or farsightedness by calculating the proper power of the IOL for your eye that will give you good vision (at the focal length you choose). This calculation is generated using very sophisticated laser equipment to measure your eyes unique characteristics, and then plugging this data into advanced mathematical modeling formulas.

 

If your eye has significant astigmatism however, simply removing the cataract and correcting the nearsightedness or farsightedness with the IOL will not completely clear your vision. Patients with astigmatism have a congenital abnormal curvature to the cornea (front part of the eye), which causes the light from an object of regard to be out of focus. Fortunately, we are now able during cataract surgery to correct astigmatism using tiny peripheral corneal incisions (LRI) that don’t materially add to the length or risk of surgery. This technique can significantly improve the likelihood that you will be glasses free for your desired focal length. This surgical correction of your astigmatism is not covered by any health insurance since it is considered “non-medically necessary”. We do offer commercial medical financing for these life changing procedures. Learn more about LRI in our LRI Information and Consent section.
