Toric Contact Lenses for Astigmatism

Toric Contact Lenses for Astigmatism can be very helpful for patients. Many people suffer from blurred vision caused by astigmatism. Astigmatism occurs when the cornea or the natural lens of the eye are unable to focus a clear image due to an irregular surface. Most people with astigmatism have an oval cornea, shaped like a football, instead of round like a basketball. In the past, patients may have been told that they could not wear contact lenses because they have astigmatism. This is no longer the case. Almost all cases of astigmatism can be treated with some type of contact lens.

Soft toric contact lenses are the most popular type of contact lens used to treat astigmatism. Good initial comfort is the main advantage of this type of lens, and the availability of trial contact lenses helps the initial fitting process. Soft Toric lenses are available in a disposable modality so long term convenience, health, and comfort are improved.

Rigid gas permeable (RGP) contact lenses are also used to treat astigmatism. Patients will have more initial awareness when wearing rigid gas permeable lenses compared to soft lenses, but long term comfort is usually good after the patient becomes accustomed to them. RGP contact lenses are able to treat greater amounts of astigmatism than soft lenses.

Hybrid contact lenses have a rigid gas permeable center and a soft lens skirt surrounding it. This type of lens tries to combine the sharp vision potential of a rigid lens with the comfort of a soft lens. The correct type of toric lens depends on the patient's prescription, corneal shape and visual needs, and they are available at D’Ambrosio Eye Care.
