Whether myopic or hyperopic, most eyes have some degree of corneal astigmatism. Corneal astigmatism means that the front part of your eye, the transparent window you look through, is not perfectly round. Instead of being spherical like a basketball, an astigmatic cornea is slightly flattened, more oval in shape like a football, with one side steeper than the other. Read more about astigmatism.
It is most common for eye surgeons to prescribe glasses or contact lenses to correct astigmatism after cataract surgery.
Toric premium lens implants
East Valley Ophthalmology offers toric intraocular lens implants (IOLs) designed to correct for both cataracts and astigmatism simultaneously. Implanted in the eye to restore single-distance vision after cataract surgery, a toric lens offers a unique design that is designed to reduce corneal astigmatism and improve uncorrected functional distance vision.
A toric lens offers these advantages over traditional lens implants:
Correction of corneal astigmatism
Enhanced clarity and quality of uncorrected distance vision.
Rich, vibrant color perception
Some models provide filtered blue light protection
A toric lens is ideal for patients who wish to correct their distance vision and are comfortable wearing glasses. Because this lens does not offer the ability to accommodate or adjust one’s vision to varying distances, glasses would be required for near and intermediate tasks for people who have this implant. A toric lens implant is also an excellent choice for those who drive at night, as it delivers great clarity with minimal reports of glare or halos under both bright and dim lighting conditions.
The toric lens is available in a wide range of optical powers, effectively correcting eyes that are nearsighted and farsighted. As each patient is unique, both in terms of physiology and viewing distance preferences, the correct power intraocular lens for your cataract surgery will be selected using biometry equipment. An in-depth discussion of your needs and options will take place with your eye surgeon before surgery.
