Toric (Astigmatism) Cataract Surgery
Toric cataract surgery uses intraocular lens implants (IOLs) that are uniquely tailored to correct the vision of individuals that have moderate to severe amounts of astigmatism. Standard and most multifocal IOLs can improve nearsightedness or farsightedness, but are not capable of improving the blur that is caused by astigmatism. Astigmatism occurs when the front surface of an eye (cornea) has an irregular shape to it. This makes light bend unequally onto the back of the eye (retina) in a way that causes blurry vision when looking at objects. Approximately 20% of patients who need cataract surgery have a clinically-significant degree of pre-existing astigmatism. Toric IOLs will typically correct distance vision, but can also be utilized for monovision—this allows one eye to be corrected for distance vision, and the other eye to be corrected for near or intermediate vision. Medicare and other insurance providers will cover all or part of surgery utilizing a traditional IOL, but they will require you to pay the difference in cost between a standard IOL and toric IOL. This will be explained in more detail at the time of your consultation.
Missouri Eye Institute-Springfield and Joplin each utilize a femtosecond laser on premises to provide laser-assisted cataract surgery for all types of cataract surgery. This laser platform allows the surgeon to create 3-D imaging of your eye, which provides more accurate information and treatment choices during your cataract removal. The laser’s advanced technology allows the surgeon to use precisely-placed laser pulses to effectively soften the cataract for removal, and it reduces risk of infection during the procedure. It helps to ensure the most appropriate condition for the best lens placement, which ultimately helps to restore your vision to its fullest potential. The femtosecond laser can also be used to correct for astigmatism, but only for mild to moderate amounts. Toric IOLs are used to correct for more moderate to severe amounts of astigmatism that the laser cannot fully correct. The use of the femtosecond laser during toric IOL cataract surgery is included in the fees for this type of implant.
Finally, if implantation of a toric IOL does not allow optimal vision for your specific visual demands, Missouri Eye Institute offers a Vision Quality Pledge that provides further laser vision correction at no additional charge within the first six months after your procedure. We want you to be able to see your best, and are the only ophthalmology group in southwest Missouri to offer a quality pledge.
