At Dr. Dorothy Park & Associates in Columbia, SC, we are experts in finding the perfect contact lenses fit. If you have astigmatism and are considering wearing contact lenses instead of glasses, let our doctor of optometry help you to explore your options.
What is Astigmatism?
Astigmatism is an irregular curvature of the cornea or the front part of the eye. A normal cornea has a round shape that is like a basketball. A cornea with astigmatism is shaped more like a football. Astigmatism usually causes blurry vision that requires prescribed vision correction.
Can Patients with Astigmatism Wear Contact Lenses?
Patients with astigmatism can definitely wear contact lenses. Our doctor of optometry will measure the surface of the eye and perform an examination. Dr. Park will develop astigmatism contact lenses that fit well and improve your vision.
Patients with a low amount of astigmatism can usually be fitted with simple soft contact lenses or rigid gas permeable lenses. Soft contact lenses are made of a lighter material and cover more of the surface of the eye. Rigid gas permeable lenses are harder, smaller, and fit directly on top of the pupil.
Soft contact lenses are often considered more comfortable than rigid gas permeable lenses. Many patients find that it takes a little longer to get used to rigid gas permeable lenses, but after a break-in period, they are just as comfortable. Rigid gas permeable lenses allow more oxygen to get to the eyes and since they move with every blink, tears can get under the lenses and form a comfort cushion.
Patients with more moderate cases of astigmatism may get their best vision from toric lenses. Toric lenses are weighted at the edges and move around to a position that compensates for astigmatism.
Specialty Astigmatism Contact Lenses
There are specialty contact lenses designed for patients with more severe cases of astigmatism. Sometimes when keratoconus is the underlying cause of astigmatism, a doctor of optometry will prescribe scleral lenses. Scleral lenses are rigid gas permeable lenses that cover a larger part of the eye. There is also a type of hybrid scleral lens that is rigid gas permeable around the eye and fades into a softer silicone on the white part of the eye.
