Refractive Surgery Week - Radial Keratotomy.

1. Scars of Radial Keratotomy.

It is an incisional refractive surgery done for myopia.

Deep, radial corneal stromal incisions are made of 90-95% depth in the paracentral and peripheral cornea.

Effect: Weakens the paracentral and peripheral cornea and causes it to bulge outwards and secondarily flattens the central cornea.


-Moderate myopia (-1 to -4D).


-Night drivers (causes glare).

-Sports players.

This procedure is abandoned now because of it's various complications.

-Diurnal fluctuations.

-Increased astigmatism and distortion.

-Instability of refractive error.

-Perforation of cornea.

-Predisposed to infectious keratitis.

-Starburst pattern and glare
