What Is PRK Eye Surgery? How It Differs From LASIK and SMILE

If you are considering laser vision correction, you have probably come across LASIK and SMILE. But there is another option that has been used for vision correction for many years: PRK eye surgery.

PRK, or photorefractive keratectomy, is a type of laser eye surgery that reshapes the cornea to correct refractive errors such as myopia, hyperopia and astigmatism. Unlike LASIK, PRK does not involve creating a corneal flap. Instead, the thin outer layer of the cornea is removed so that the underlying tissue can be reshaped with a laser.

This difference may sound small, but it can affect the recovery process and whether PRK is suitable for a particular patient. At Jehan Eye Clinic, a trusted eye clinic in Mumbai, Dr. Kareeshma Wadia evaluates the health and shape of the cornea, vision prescription, and other important factors before recommending the most suitable vision correction procedure.

What Is PRK Eye Surgery and How Does PRK Treatment Work?

PRK eye surgery is a form of laser-based PRK vision correction designed to change the shape of the cornea so that light can focus more accurately on the retina.

Before surgery, your eyes undergo a detailed examination. The ophthalmologist checks your prescription, corneal thickness, corneal shape and overall eye health. These tests are important because not everyone who wants laser vision correction is necessarily a suitable candidate.

During PRK treatment, the surgeon first removes the thin epithelial layer covering the cornea. A laser is then used to precisely reshape the corneal tissue according to the patient's prescription. A soft contact lens is usually placed over the eye temporarily to protect the healing surface while the epithelium grows back.

One of the main characteristics of PRK laser eye surgery is that there is no corneal flap. This makes PRK an option worth considering for some patients with thinner corneas or those for whom flap-based procedures may not be ideal. Suitability, however, needs to be determined through a proper eye examination.

PRK vs LASIK: What Is the Difference Between These Laser Eye Surgeries?

The biggest difference when comparing PRK vs LASIK is how the surgeon reaches the corneal tissue that needs to be reshaped.

In LASIK, a thin flap is created on the cornea. The laser reshapes the underlying tissue, after which the flap is repositioned. PRK does not create this flap. Instead, the surface epithelial layer is removed and allowed to heal naturally after the laser treatment.

Because of this, recovery tends to be different. LASIK patients often experience relatively quick visual recovery, while PRK generally involves more discomfort and a longer period before vision becomes clear.

PRK can be considered for patients with certain corneal characteristics or lifestyles where avoiding a corneal flap may be beneficial. For example, people involved in activities where there is a higher risk of eye trauma may sometimes be evaluated for PRK.

However, there is no universal winner in the PRK vs LASIK comparison. The better procedure depends on the patient's eyes, prescription, corneal measurements and lifestyle.

PRK vs SMILE: Which Vision Correction Procedure Is Right for You?

When considering PRK vs SMILE, the procedures differ in both technique and recovery.

SMILE, or Small Incision Lenticule Extraction, uses a femtosecond laser to create and remove a small piece of corneal tissue called a lenticule through a tiny incision. Unlike LASIK, SMILE also does not require the creation of a large corneal flap.

PRK, meanwhile, works through the corneal surface. The epithelial layer is removed before the laser reshapes the cornea.

Both procedures are forms of laser vision correction, but they are not interchangeable for every patient. The suitability of one procedure over another may depend on the type and degree of refractive error, corneal thickness and shape, tear-film health and other clinical findings.

If you are comparing PRK with LASIK or SMILE, it is better to think beyond recovery time or convenience. A procedure that worked well for someone you know may not necessarily be appropriate for your eyes.

PRK Surgery Recovery: What to Expect After Laser Vision Correction

Recovery is one of the biggest differences patients notice when comparing different refractive surgery options.

After PRK surgery, the surface layer of the cornea needs time to heal. During the first few days, patients may experience discomfort, watering, light sensitivity and blurred vision. These symptoms generally improve as the surface heals.

Vision may remain somewhat hazy during the early recovery period and can continue to improve gradually over the following weeks. The exact recovery timeline varies from person to person.

Your ophthalmologist may prescribe medications and provide specific instructions for protecting the eyes during healing. Follow-up appointments are important because they allow the doctor to check the cornea and monitor recovery.

It is also important not to rub the eyes during the healing period and to follow instructions regarding swimming, makeup, exercise and other activities.

At Jehan Eye Clinic, Dr. Kareeshma Wadia guides patients through the recovery process and explains what they can realistically expect at each stage. Understanding the recovery period beforehand can make the experience much easier and help patients avoid unnecessary worry.

Is PRK Eye Surgery Right for You? Consult an Ophthalmologist in Mumbai

Not everyone with glasses or contact lenses is automatically a candidate for refractive surgery. A detailed evaluation is necessary before deciding whether PRK eye surgery, LASIK, SMILE or another option is appropriate.

Your ophthalmologist in Mumbai may assess:

• - Your current glasses or contact lens prescription
• - Corneal thickness and shape
• - Stability of your prescription
• - Tear-film and eye-surface health
• - Overall eye health
• - Your age and medical history
• - Your expectations from surgery

These factors help the surgeon determine whether PRK treatment is suitable and whether another form of refractive surgery may be more appropriate.

It is also important to have realistic expectations. Laser vision correction can reduce dependence on glasses or contact lenses, but the outcome varies between individuals, and no procedure can guarantee perfect vision in every case.
