Corneal refractive surgeries for the correction of myopia, hyperopia, astigmatism and hyperopia are quick and effective procedures, and have been growing in popularity over the last two decades. However, post-surgery corneal ectasia remains one of the most feared surgical complications. This is where the biomechanical integrity of the cornea begins to fail, with progressive thinning of the stroma, steepening of the cornea, irregular astigmatism, and decreased distance visual acuity. Laser-assisted in-situ keratomileusis (LASIK) is currently the most common refractive surgery procedure. It uses a femtosecond laser or a microkeratome to cut a thin flap on the surface of the cornea. Corneal tissue is then photoablated to correct the refractive error and the flap is then replaced at the end of the procedure. Newer techniques such as small incision lenticule extraction (SMILE) make use of .. View More»
