It is a type of refractive surgery which reshapes the cornea by destroying microscopic amounts of tissue from corneal stroma, using the computer-controlled beam of light (an excimer laser). The difference from LASIK is that all the epithelium is removed (and a bandage contact lens must be used). Recovery time is much longer with PRK than with LASIK, though the final outcome (after 3 months) is about the same (very good). More recently, customized ablation have been performed either with LASIK or PRK. | ||
