WHAT IS PRK?
Photorefractive Keratectomy (PRK) is a form of eye procedure used to fix refractive errors like Nearsightedness or Myopia (trouble in reading), Farsightedness (difficulty in seeing things at a distance) and Astigmatism (focus disruption of near and distant vision).
PRK does not allow the creation of a flap, so it is recommended for patients with thinner corneas or irregular topography.
HOW IT WORKS
BEFORE THE PROCEDURE
The specialist will have your eyesight tested.
If you wear contact lenses, you will be asked to discontinue wearing them for a few days (in case of soft contact lenses) and a few weeks (for rigid gas permeable lenses) prior to the assessment/screening.
You may be also prescribed antibiotic eye drops that need to be started 3-4 days before the procedure.
DURING THE PROCEDURE
5-10 minutes per eye is all it takes to perfect your vision with PRK. You may be administered anaesthetic eye drops before beginning.
An eyelid holder/speculum will be positioned on each eye to keep you from blinking.
The corneal surface cells will then be removed with the help of a laser/spatula.
Then, the laser programmed specifically to match your eye measurements will reshape the cornea.
A non-prescription, clear contact lens is placed as a bandage on each eye.
AFTER THE PROCEDURE
Post procedure, you will return home after resting at the hospital. Do not schedule anything else for that day as you need to rest well to speed up recovery.
The specialist may need to see you a day after the procedure to assess the results and your level of comfort.
Let the specialist know if the bandage lenses fall off or get dislodged.
You will have to return within a week to have them removed from the eyes.
NOTE: Do not rub your eyes, especially for the first 3-5 days. If you experience pain or notice any sudden decrease in vision, contact your specialist without delay.A few routine eye checkups will be done to ensure everything is perfect.

OUR EYE SPECIALISTS
How long does PRK take?
The entire PRK or Photorefractive Keratectomy gets completed in just 15 minutes. The cornea reshapement usually takes up to 5 minutes.
Is PRK safe?
PRK is a tested procedure with a proven track record of success & is entirely safe. About 90% of the people opting for PRK have 20/20 vision without contact lenses or glasses after a year of the procedure & about 95% of the people have 20/40 vision or better without contacts or glasses.
Does PRK hurt?
Your specialist will apply numbing eye drops prior to the procedure to block any feeling of pain. While the threshold for discomfort is unique for each, most people do not report the process as painful. As the epithelial cells regenerate in your eye, there can be temporary discomfort, including throbbing or pain. The expert will advise a pain medication to control these.
Can I have PRK on both eyes?
Yes. You can have the procedure on both eyes or just one eye, according to your preference.
