REFRACTIVE SURGERY IN CHILDREN [PDF]
Ophthalmology Clinics of North America, 2001 Refractive surgery techniques, especially those using laser ablation, have revolutionized the treatment of refractive errors. The short-term results have been well studied in adults, but long-term outcomes are not known. No good studies exist to tell us whether the pediatric eye responds the same as the adult eye to these techniques, but there is ...
