Limbal Relaxing Incisions for Treatment of Astigmatism

Astigmatism usually occurs when they cornea, the front layer of the eye, is not perfectly Limbal Relaxing Incisionsround or spherical. The cornea is too steep in one direction and too flat in another, and is shaped more like an egg than a ball. This results in distortion of the image that is focused on the back of the eye. Astigmatism can be eliminated with glasses or contact lenses, but there is also a surgical way to correct the condition.

Your surgeon can use a diamond blade to correct the shape of your cornea by creating limbal relaxing incisions. The limbus is the border between the clear part (cornea) and the white part (sclera) of the eye. By making precise incisions in the steep areas of the limbus the cornea can be made more spherical in shape. The procedure is done with topical anesthesia, usually at the time of cataract surgery, although it can also be done in the office.

Limbal relaxing incisions reduce or eliminate astigmatism and thus increase the chances of better vision without eyeglasses. Reading glasses will usually still be necessary to read and do close work.

At Palo Alto Eye Group, our limbal elaxing procedures are guided by preoperative measurements of the corneal thickness using a high frequency ultrasound (pachymeter). We then customize the depth of the relaxing incisions with an adjustable diamond blade, giving us much more predictable results than incisions made with a non-adjustable blade. Few practices offer this degree of customization and predictability; just another detail that sets Palo Alto Eye group apart from the rest.
