Astigmatism and Cataract Surgery

Question: I have a question about astigmatism correction with eyeglasses and cataract surgery. I am facing cataract surgery have some astigmatism and do not wish to use the special toric lens implant. Will eyeglass correction for astigmatism provide the same result?


Answer: For patients having Cataract Surgery who have preexisting astigmatism, it will need to be corrected in order to get the best possible vision after their Cataract operation. There are three primary methods of correcting astigmatism for Cataract patients. These include astigmatism correcting toric lens implants, Limbal Relaxing Incisions (LRI) and eyeglasses. Another alternative is Laser Eye Surgery such as LASIK however with the popularity of toric lens implants this is not used much anymore. Each method has its own advantages and disadvantages. Astigmatism correcting lens implants probably provide the most normal and natural vision correction as they are placed right in the eye-they do cost a little more but generally provide very good vision such that patients typically no longer need to wear eyeglasses to see at distance after Cataract Surgery. Limbal Relaxing Incisions (LRI) can also be used to correct astigmatism but perhaps with a slight bit less precision than the Lens Implants. Astigmatism correction in eyeglasses after Cataract Surgery generally provides excellent vision correction-equivalent to toric lens implants-but does require the wearing of glasses to see clearly and thus creates the same inconvenience, reflection issues and barriers as any other eyeglass prescription.
