Risk factors and specialized contact lens fitting for post Lasik corneal ectasia

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.
