Currently, LASIK (laser-assisted in situ keratomileusis) is the most commonly performed laser vision correction procedure in the world (over 10 million surgeries each year); however, it has a major disadvantage in that it weakens corneal integrity and structure and predisposes to complications such as keratectasia or keratoconus (bulging of the cornea) and vision loss. An alternative is photo-refractive keratectomy (PRK), which removes the corneal epithelium and anterior stroma while minimizing the incidence of keratectasia or keratoconus. The primary drawbacks of PRK are that it requires a longer recovery time (the corneal epithelium must regenerate from the patient's own LSCs) and may result in blurry vision and pain due to corneal pain nerve fiber exposure after removal of the epithelium. Coverage of exposed corneal stroma tissue immediately after surgery with LSC-derived corneal epithelial cells will solve this key bottleneck and make laser eye surgery safer and more comfortable for millions of people.
