Advanced Surface Ablation
Dr. Paul Casey
Henderson / Las Vegas PRK Specialist
As a leading Las Vegas PRK surgeon, Dr. Paul Casey has treated numerous patients from Las Vegas, Henderson and throughout the state of Nevada. He offers PRK (also known as advanced surface ablation) for patients who desire to reduce their dependence on glasses but cannot undergo LASIK due to factors such as thin corneas and/or large pupils. In addition, many PRK Las Vegas patients pursue this procedure because it does not involve the creation of the corneal flap, which eliminates the risk of flap-related complications. In the paragraphs below, the highly skilled Las Vegas and Henderson PRK surgeon Dr. Casey explains the PRK treatment and the results that can be achieved through it.
ASA (Advanced Surface Ablation), also called PRK (photorefractive keratectomy), was at one time the most common laser eye surgery. It uses the same excimer laser as the Custom LASIK procedure to reshape the outer layer of the cornea to correct for nearsightedness, farsightedness, and astigmatism. These days LASIK is more common, but ASA is still an alternative for patients who cannot undergo LASIK Surgery.
Reasons to consider ASA:
Astigmatism (irregularly shaped cornea).
Cornea too thin for LASIK.
Pupil too large for LASIK.
In preparation for surgery, anesthetic eye drops are administered. Next, a speculum is placed in the eye to keep the eyelids open, which is normally not uncomfortable. While the patient fixes his or her gaze on a target, the laser reshapes the cornea by removing tissue (a process called ablation), which is controlled and closely monitored by the doctor. The laser is actually guided by a detailed map of the patient’s eye which has been programmed into a computer beforehand. The ablation usually takes around a minute for each eye, depending on how high the patient’s vision prescription is. Most Las Vegas PRK patients feel no pain during the procedure. After PRK is completed, a bandage contact lens is placed on the eye. The patient may go home shortly after the procedure; however, someone else must drive or alternate transportation must be arranged.

recovery; however, most patients don’t require it since only minor
discomfort is experienced. The doctor will also schedule several
check-up appointments to monitor the healing process, followed by
periodic visits over the next several months. During the recovery
process, the patient should rest, and refrain from any strenuous
activities for at least a week. Most patients can return to work in a
day or two, though it is best to take a few days off to ensure a smooth
