LRI (Limbal Relaxing Incisions)

Limbal relaxing incisions are for reducing or eliminating your astigmatism at or after cataract surgery. Eliminating your astigmatism will give you better naked-eye vision than you would have without correcting it. LRIs are for mild to moderate degrees of astigmatism. They consist of a partial-thickness groove made in the very periphery of the cornea. LRIs will not affect your care or restrictions after the surgery. The results are not entirely consistant, so at times they only reduce rather than eliminate the astigmatism. Sometimes they have no effect at all.
For patients who have a large degree of astigmatism, LRIs are not the best option. LRIs can effectively and safely correct up to about 1.5 diopters of astigmatism. For patients who have more astigmatism than that, a toric lens implant is a better option. Also, toric lenses have a much higher success rate than LRIs, so toric lenses are a much better choice if you find it really important to see well naked-eye. See the discussion on toric implants in the section “Cataract Center: Intraocular Lenes” on this web site.
LRIs can also be performed after the surgery, in the office. The usual reason to do them is if all of the astigmatism is not corrected by a toric implant.
There is no out-of-pocket charge for LRIs.
