Scleral Lenses for Astigmatism

Scleral lenses are a great solution for those with astigmatism. That’s because the lens masks the astigmatism by creating a smooth, regular optical surface over the irregular cornea. And, because of their shape, it allows the eye to properly focus light and thus ensures sharp vision and comfort. For this reason, scleral lenses are an ideal solution for those with astigmatism. If you have been told that your astigmatism is too severe to wear contacts, keep reading to learn more about scleral lenses.

What is Astigmatism?

Astigmatism is a common refractive error caused by an irregular curvature of the cornea. This causes the eye to refract light incorrectly, creating two focus points of light entering the eye. Because of this, vision is blurred at all distances. In mild to moderate astigmatism, the blurred vision can be easily corrected with prescription glasses. But for patients with high levels of astigmatism, standard soft contact lenses are usually not an option.

Soft Contact Lenses vs Scleral Lenses

Generally speaking, standard soft contact lenses are usually not a good option for correcting high levels of astigmatism. That’s because there is a limit to the amount of astigmatism standard soft contacts can correct. They also move around on the cornea due to the irregular shape of it. Scleral lenses, on the other hand, sit on the sclera and not the cornea. And, because they are rigid and maintain their shape, it allows the eye to properly focus light and thus ensures sharp vision and comfort.

What Makes Scleral Lenses Special?

What makes a scleral contact lens so special is the size. Because of their size, scleral lenses functionally replace the irregular cornea with a perfectly smooth surface. This helps to correct vision caused by astigmatism, keratoconus and other corneal irregularities. Additionally, the space between the back surface of a scleral lens and the cornea acts as a fluid reservoir. As a result, it also provides comfort for those with mild to severe dry eyes that otherwise would not be able to tolerate wearing contact lenses.
