Limbal Relaxing Incisions (LRIs)

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 traditionally would make small relaxing incisions in the limbus with a blade, which allowed the cornea to become more rounded when it heals. Now, these same incisions that in the past were made with a blade are now made with the LenSx Laser, for more precise reduction of astigmatism at the time of cataract surgery. Limbal relaxing incisions are not commonly done at Omni anymore since the introduction of laser cataract surgery.

Limbal Relaxing Incisions (LRIs)

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 near prescription will usually still be necessary to read and do close work.  Your doctor of optometry and your Omni Eye Surgeon will discuss the options that make the best sense for you.

It is important to note that insurance does not cover the cost of the limbal relaxing incisions, either done with the blade or the LenSx laser.
