PRK (photorefractive keratectomy) is a laser eye surgery used to correct mild to moderate nearsightedness, farsightedness, and/or astigmatism by changing the shape of the cornea. It is a no flap safer alternative to LASIK.

We use advanced technology to individualize your vision correction. The iDesign Refractive Studio technology is groundbreaking because it can improve how much you can see and how well you can see.

What are the benefits of PRK over LASIK?

PRK gives the patient safer surgical option while still providing the same laser technology and outcome as LASIK. During the procedure, the surgeon avoids the cutting of a flap on the corneal tissue which in turn minimizes potential flap complications as well as intraoperative and post-surgery complications, including severed nerve endings, microscopic wrinkles, irregular astigmatism, and inflammation.  Because no flap is created with PRK, it is a great procedure for patients who have thin corneal tissue. It can also be a good choice for those who have dry eyes since the flap method sometimes makes dry eye symptoms worse.

Who would be an ideal candidate for PRK surgery?

If you are tired of wearing corrective lenses or eyeglasses, you may want to consider PRK surgery.  Your eye doctor will review whether you are a candidate for PRK surgery during your preoperative exam and consultation.  Patients with thinner corneas or with corneal surface irregularity would be ideal candidates for PRK surgery, as PRK disrupts less corneal tissue than a comparable LASIK surgery. 

How do you prepare for your PRK screening visit?

If you wear contact lenses, stop wearing them at least 3 days before your visit. You should also bring your current eyeglasses so your prescription can be reviewed.  If you wear rigid gas permeable contact lenses, stop wearing them at least 3 weeks before your PRK screening visit. 

What can you expect during your PRK consultation?

During your consultation, your eye doctor will discuss what you should expect during and after PRK surgery. Your eye doctor will also review your medical history and test your eyes–taking the measurement of the refractive error in each eye, and mapping of your corneal shape.  You can schedule your PRK surgery at the conclusion of your consultation.

What happens during the PRK procedure?

During the procedure, using numbing drops, the epithelium (a thin layer of clear, protective skin that covers the corneal surface) is removed.  Then in a matter of seconds, the Excimer laser sculpts the surface, removing microscopic layers of tissue. After treatment, a protective clear bandage contact lens is then placed on the eye to help with the healing process.  The procedure is done under topical anesthesia and takes about 10 minutes to treat both eyes. 

Are there any side effects associated with PRK surgery?

After PRK surgery, you may experience sensitivity to light within the first few days. Other temporary side effects may include glare symptoms related to light scattering or halos around images. 

What is the typical outcome after PRK surgery?

Approximately 90 percent of PRK patients have 20/20 vision without glasses or contact lenses 1 year after the surgery. Over 95 percent have 20/40 or better without glasses or contacts. 

What age group is PRK recommended?

PRK surgery is best for ages 20+ years old.  In your early to mid-40s, you lose some ability to focus on nearby objects (presbyopia), which results in difficulty reading small print or doing close-up tasks. Talk to your eye doctor about the best eye surgery procedure for your age group.
