LRI (Limbal Relaxing Incisions) 
Limbal Relaxing Incisions is a newer technique that is a variation of Astigmatic Keratotomy. Astigmatism occurs when the eye begins to lose it's spherical shape, become more like an oval, or a football. Uncorrected astigmatism can lead to ghosting and double images. The primary difference between LRI and AK is where AK makes it's cuts on the actual cornea, LRI makes it's cuts on the limbus, which is the boundary area connecting the cornea and sclera. By cutting the limbus instead of the cornea, a great deal of the potential side affects associated with AK are avoided, including the potential for halos and glare. The surgery itself procedes in much the same was as AK. Numbing drops are placed in the eye. The doctor then makes a series of small cuts in the limbus in a pattern dictated by the patients level of astigmatism. These cuts cause the limbus to relax into a more spherical shape.
LRI is primarily performed in conjunction with another surgery. As most people who go in for refractive surgery have some level of astigmatism in conjunction with their primary vision condition, it has become a fairly popular procedure. Check our news link for recent developements.
