Advanced Surface Ablation
(Modern PRK, LASEK, epi-LASIK)
Advanced Surface Ablation (ASA) is an excimer laser vision correction technique that does not require the creation of a flap. This technique was introduced in the USA and FDA approved in 1995 as PRK (photorefractive keratectomy). As technology has advanced, PRK has evolved into what is known today as Advanced Surface Ablation.
Modern ASA has improved from its beginnings and now provides one of the most precise and predictable refractive surgery procedures available. So much so, that, until 2007, it was the only laser vision correction procedure allowed to be performed on US Military fighter pilots and NASA astronauts. It is still considered the procedure of choice for people with certain occupations and hobbies.
After your comprehensive evaluation at Parschauer Eye Center, you and your surgeon will determine which laser vision procedure is best for you.
The Advanced Surface Ablation Procedure
- Numbing drops are placed onto the surface of the eye.
- The very thin front surface layer of the cornea (the corneal epithelium) is gently lifted.
- Excimer laser reshapes the cornea.
- A contact lens is placed on the surface of the eye which allows the epithelium to heal beneath it.
After the ASA procedure is completed, functional visual recovery is typically achieved in 3-4 days. A lifetime warranty is available for $299.
