What is Corneal Ablation Surgery? | Providence Eye
Corneal surface ablation is a procedure where a vision correction surgeon gently removes the epithelium (surface) of the cornea and treats the refractive error on the front surface of the cornea. Corneal surface ablation is an alternative to LASIK that’s also commonly known as photorefractive keratectomy or PRK .
