AK will diminish or eliminate astigmatism. Astigmatic Keratotomy is often performed in combination with other refractive procedures. LRI is a modification of radial keratotomy and are often performed with RK or cataract surgery. To treat astigmatism, the cornea must be made more spherical or uniformly curved. This causes the cornea to relax and become more round.
Most people have some degree of astigmatism.
Astigmatism is not a disease, but is actually a vision condition that is quite common. The causes of this irregular shape are unclear. In some cases, it may be hereditary or it may result from such factors as pressure of the eyelids on the cornea, incorrect posture or an increased use of the eyes for close work. All Rights Reserved.
