Abstract

Corneal ectasia remains one of the most insidious complications encountered after refractive surgery including laser in situ keratomileusis (LASIK), radial keratotomy (RK) and phptprefractive keratectomy (PRK) and more recently small incision lenticule extraction (SMILE). Ectasia after refractive surgery is a progressive increase in myopic defect, with or without irregular astigmatism, associated with fast keratometric steeping and topographic asymmetric inferior corneal steeping. Over time, there can be associated thinning of the central and paracentral ectatic corneal tissue. Normally this it come to patient’s clinical attention when there is associated loss of uncorrect distance visual acuity (UDVC) [1, 2].
