Postoperative complications of excimer laser photorefractive keratectomy for myopia

As outlined earlier, a wide range of clinical problems may currently be encountered after PRK. Continual refinement and improvements in excimer laser photorefractive keratectomy have led to increased safety and predictability of this procedure. Unfortunately, no surgical intervention can ever be entirely without risk of complications. At present, mild to moderate (under 7.5 D) myopic patients undergoing surface PRK have a less than 4% risk of significant complications that adversely affect their best visual acuity at 1 year. As photorefractive technology continues to evolve and our understanding of how the cornea responds to the induced change increases, complications from these procedures will be further reduced.
