Limbal Relaxing Incisions for Astigmatism Correction

Almost everyone has a small amount of astigmatism; however for some the amount is significant enough to create some visual problems. Astigmatism means that the cornea (which is the clear dome over the colored portion of the eye) is shaped more like a football instead of being round like a basketball. This causes the light rays entering the eye to be bent in a manner that prevents them from focusing at one point, leading to blurred and distorted vision for both distance and near.

Limbal relaxing incisions (LRIs) are a form of astigmatic keratotomy for the correction of mild to moderate amount of astigmatism. The procedure entails creating small arc incisions in the peripheral portion of the cornea usually at the steeper parts to create a"relaxing" or flattening effect with healing to allow the cornea to become more round.

Limbal relaxing incisions (LRIs) have gained widespread acceptance amongst cataract surgeons where it is often combined with the cataract operation. The procedure is safe and serious complications are extremely rare. There is usually little or no, post-operative discomfort and usually no associated glare or starbursts which can be seen with other procedures.

Limbal Relaxing Incisions are for those:

• who have low to moderate astigmatism
• want to minimize their dependence on glasses or contacts
• have no health issues affecting their eyes

As to what can be expected after the procedure, most patients appreciate a dramatic improvement in their vision the first day after surgery. Since everyone heals differently some patients may take longer than others to notice their visual improvement.
