Why Advanced PRK Surgery?
Why Advanced PRK?
Prior to the development of LASIK, Photorefractive Keratectomy or PRK Surgery was the first astigmatism.It has undergone many advances and innovations since its introduction more than 20 years ago.
What is Advanced PRK vision correction?
Advanced PRK is a surgical procedure that corrects refractive errors. It is also commonly known ASA / ASLA (Advanced Surface Laser Ablation) and LASEK.
Developed in the 1980s and evolved in 1990s it has successfully transformed the vision of millions of people.
During Advanced PRK, the surgeon gently polishes away the outer skin of the eye (epithelium) and uses a cool beam of laser light to sculpt the corneal tissue into a new shape to correct the refractive error.
A ‘bandage’ contact lens is placed on the eye to promote comfort and healing. The surface skin grows back over the next few days.
Following Advanced PRK eye treatment using the process of Lasersight® it is normal to feel some discomfort on the second and third day post-surgery as the cornea’s surface regenerates. Most patients will be completely comfortable by day four.

Advanced PRK Laser Eye Surgery Procedure At-A-Glance
Step 1: PRK Preparation
Anaesthetic, antibiotic and anti-inflammatory eye drops are applied to the eye. An icepack is held over the eye for 10 minutes.
Step 2: Surface Adjustment
The surgeon gently brushes away the outer layer of the cornea.
Step 3: Cornea Reshaping
Computer-controlled pulses of cool laser light are applied to the cornea.
Step 4: Advanced PRK Completion
A ‘bandage’ contact lens is placed onto the eye to promote comfort and healing. This lens remains on the eye for 3 days, until removed by the optometrist.
Generally, vision will be good enough to drive within 4-5 days following your Advanced PRK surgery using the process of lasersight®, and you may return to work within a week. However, you may not achieve your best vision until four weeks after PRK surgery as the epithelium smoothes.
What’s the difference between Advanced LASIK and PRK surgery?
In Advanced PRK surgery, the surgeon carefully brushes away the cornea’s outer skin (epithelium), before using the excimer laser to sculpt the cornea to the required shape.
After Advanced PRK surgery, a ‘bandage’ contact lens is placed on the eye to promote comfort and healing while the epithelium regenerates naturally over the next few days.
This process differs from LASIK in its preparation of the cornea, since in LASIK the surgeon cuts a micro thin flap in the cornea, gently pulls it back, and then replaces the flap to its normal position after corneal reshaping with the laser.
