Surface Ablation (PRK & LASEK) in Northern California
Shaping the Cornea for Light Refraction
Utilizing the precision and accuracy of the excimer laser, surface ablation changes the shape of the cornea to improve the way light is focused or "refracted" by the eye for myopia and hyperopia, with or without astigmatism. After eye drop anesthesia is used to numb your eye, the epithelium (the outermost layer of the eye) is removed, and ultraviolet light and high energy pulses are used to reshape the outer cornea. The excimer laser is ideal for corneal surgery because it emits a "cool" or non-thermal light beam that minimizes thermal or heat damage to surrounding tissue.
Immediately following the procedure, a bandage contact lens is placed over the eye for three to five days to protect the eye while it heals. Surface ablation has a lengthier healing process and more discomfort than LASIK eye surgery. Patients may report some discomfort after the procedure until the outer portion of the cornea (epithelium) heals, usually within 48 to 72 hours. Patients with higher prescriptions before surgery often see a dramatic improvement in their vision within the first week, with the overall healing process continuing for the next few months.
