The myopic eye is longer and the eye wall is thinner. Myopes have more retinal detachments, floaters, and vitreous degeneration and may have more glaucoma. Corneal surgery can improve visual acuity in most cases, but it does nothing to address these comorbid conditions. Treating myopia with corneal surgery is like treating obesity with liposuction. The cosmetic result may be excellent, but the patient will still have deeper pathology that could result in blindness.
Corneal surgery is the most heavily marketed eye medical procedure in history.
The money spent developing and selling this treatment would have been better spent on understanding the etiology of this disease and its prevention. It is an elective procedure that carries the risk of serious and permanent complications. Corneaplasty could carry fewer risks. However, while both corneaplasty and corneal surgery are treatments for refractive errors, neither is a total cure for myopia. In my opinion, they are both poorly thought-out approaches to the problem.
