The outer layer of the eye can be divided into three areas: the cornea, the sclera and the limbus. The cornea is the clear part, or the window, that covers the iris and the pupil. The sclera is the white part of the eye. The limbus is the thin area that connects the cornea and the sclera.
Limbal relaxing incisions (LRIs) treat low to moderate degrees of astigmatism. As the name suggests, the surgeon makes small relaxing incisions in the limbus, which allows the cornea to become more rounded when it heals. LRIs are placed at the very edge of the cornea (in the limbus) on the steepest meridians. 
Limbal Relaxing Incisions are for those:
- who have astigmatism
- want to reduce or eliminate their dependence on glasses or contacts
- have no health issues affecting their eyes
These incisions are usually made at the time of cataract surgery to reduce or eliminate the astigmatism and thus increase the chances for better vision without eyeglasses. A prescription for near vision will usually still be necessary to read and do close work. The doctors of Karlik Ophthalmology will discuss the options that make the best sense for you.
