PRK (photorefractive keratectomy) was actually the first type of vision correction procedure approved by the FDA in 1995 to reshape the cornea (even before LASIK). Since then millions of PRK procedures have been performed to correct nearsightedness, farsightedness and astigmatism, helping most patients see more clearly without glasses or contacts.
Patients who are not good candidates for LASIK due to thin corneas or other conditions may be good candidates for PRK and end up with clear vision like most LASIK patients.
We take many conditions into consideration to ensure that your eyes are healthy enough for the procedure: simply needing glasses to see is not the only requirement.
It is absolutely crucial that you undergo a comprehensive eye exam to determine if PRK is right for your eyes. If any doctor agrees to perform the procedure without an exam, please consult our PRK doctors in San Francisco to arrange for a free, no-obligation PRK Consultation at Mosaddegh Eye Institute. We will be up-front and honest about your eye health, what to expect from PRK and the potential risks. Most importantly, we will let you know if PRK is a safe vision correction option for you.
PRK can correct the corneal shape to allow for clear vision.
PRK is often recommended for patients who have thin corneas. Rather than creating a flap on the corneal surface (as in LASIK), your doctor removes the outermost layer of corneal tissue so the reshaping process can be administered. This is an outpatient procedure that takes a bit longer to recover from than LASIK because the eyes need time to regenerate the epithelial layer on the cornea.
The best way to find out if PRK in San Francisco might help you achieve clear vision is by scheduling a free PRK Consultation with us. We will assess your corneal thickness, eye health and other factors to determine if this might be a safe and effective procedure for you. The Consultation is also a time when you can get your questions answered and learn more about our PRK technology, experience and results.

Prior to the PRK procedure, your doctor applies numbing eye drops to block the feeling of pain. While every person has their own unique threshold for discomfort, most patients do not report that the process is painful. The PRK recovery process may bring you temporary discomfort as the epithelial cells regenerate on your eye. These discomforts can include pain, throbbing, a foreign substance feeling, etc. This can be managed with pain medications outlined by your doctor.
The full PRK procedure takes 10 minutes, from the time you enter our surgical suite until you go into the recovery area. The excimer laser treatment where we reshape your cornea takes less than 3 minutes!
Although considered a relatively safe medical procedure, PRK carries some element of risk. Complications of PRK can include:
Because your eyes need time to recover an intact outer layer on the cornea, expect to take 1 day off from work to recover from PRK in San Francisco. Your best vision results will probably take longer to achieve, but most patients are able to return to non-strenuous activities after 1-2 weeks. It is important to keep your follow-up visits so your doctor can monitor your progress.
Your vision is constantly changing. While PRK is performed to correct a refractive error, other vision conditions can develop that may require you to need glasses in the future. Most people over age 40 develop a condition called presbyopia. This is a gradual stiffening of the eye lenses that makes it difficult to focus on things up close like reading material. Even if you had a successful PRK procedure, you may need over-the-counter reading glasses as you grow older. There are also different surgical methods to correct presbyopia. If you are experiencing this condition and are frustrated with reading glasses, contact us to learn about your treatment options.
There are several conditions that must be met to be considered for PRK:
The only way to know if you meet these requirements is by having a comprehensive PRK Consultation with us. It’s free and will let you know for sure if this is a safe option for vision correction for you.
It is not likely that the cost of PRK will go down in the future. In fact, as technology changes the costs may actually rise over time. While the price of PRK is a definite concern for many people, you don’t want to shop for the lowest price if it means sacrificing quality. When you are researching PRK centers, be sure to weigh the cost against:
You only have one set of eyes, so make sure you put your vision care into a doctor and center you trust – a center like Mosaddegh Eye Institute.
Yes. You can choose to have the surgery on both eyes or just one eye at a time.
Patients should wait at least 2 weeks before wearing makeup. We recommend that patients purchase new eye makeup to avoid infection.
