Abstract: Corneal ectasia following Lasik is a
devastating complication of laser in keratomileusis (Lasik). The classic
clinical sign of the condition is a progressive steepening and thinning of the
cornea after excimer laser refractive surgery that reduces both uncorrected visual
acuity and corrected visual acuity with spectacle. Risk factors for the
development of ectasia after Lasik include high myopia prior to surgery, low
residual stromal bed thickness, low preoperative corneal thickness, forme
fruste keratoconus and multiple laser enhancements. Management of postoperative
ectasia with specialized contact lens remains the main course of treatment for
patients who do not wish to go through other surgical options or corneal
transplantation. [Samuel Tung-HsingChiang, David Chao-Kai Chang, John Ching-Jen
