Correcting Astigmatism with Cataract Surgery

Astigmatism correction during cataract surgery will improve your visual outcome, especially with specialty multifocal lenses that reduce or eliminate your dependence on glasses. This can be achieved by any of the following methods:

  • Toric Intraocular Lenses (Toric IOL) – A Toric IOL is a monofocal IOL that corrects for astigmatism. Corneal topography measurements will determine the axis of astigmatism to which this lens needs to be oriented, and proper placement can eliminate up to two diopters of preexisting corneal astigmatism. Dr. Iskander is the first surgeon in south Texas to implant the newest generation toric intraocular lenses by Johnson and Johnson.
  • Limbal Relaxing Incision (Astigmatic Keratotomy) – Limbal relaxing incisions are made on the corneal surface using specialized blades. These incisions of predetermined specific length and location can relieve existing astigmatism. These incisions do require specific testing and skills, and fortunately Dr. Iskander has performed numerous LRIs in his time at San Antonio Eye Specialists. Although slightly less predictable than Toric IOLs, LRIs can eliminate up to two diopters of corneal astigmatism. They are usually combined with multifocal lenses for optimum effect.
  • Combination of Toric Intraocular Lens and Limbal Relaxing Incision – A combination of both Toric IOLs and limbal relaxing incisions can be used to eliminate higher degrees of astigmatism, up to four diopters.

“I was scared to have cataract surgery after I was diagnosed by my optometrist. After going to several ophthalmologist in town, I decided to go with Dr. Iskander of San Antonio Eye Specialists because I felt most comfortable with him. He took the time to explain the difference between modern cataract removal and old fashion cataract surgery like my mother had. After undergoing laser-assisted cataract removal, I can see clearly again! I also chose a premium lens implant which has freed my from reading glasses and bifocals for nearly all activities! Thanks again Dr. Iskander!”

"I was very pleased with my experience with Dr. Nader G. Iskander.It was good to be treated with professionalism and care. When I say the doctor and all the other employees of the Doctors Care made me feel that I was in safe hands and even made me smile when I left, then you can believe they are the best. I am truly grateful and highly recommended San Antonio Eye Specialists."

I highly recommend Dr. Nader Iskander and his staff for anyone who is in need of professional vision care servicies. Dr. Iskander performed successful Cataract surgery on me for both of my eyes during 2013 when I was 64 years old. My vision improved immediately to 20/20. There was no pain or side effects. I go back once a year for an annual eye exam with Dr. Iskander. I am happy to say that I have had no problems with my vision since my Cataract surgery. I just had my annual eye exam with Dr. Iskander at SA Eye Specialists and I am glad to say my vision is still 20/20 at 70 years old.
