In the world of eye surgery, there are various procedures that are used to correct vision problems. One such procedure is PRK (Photorefractive Keratectomy) eye surgery. This procedure has been widely used to correct nearsightedness, farsightedness, and astigmatism.

Unlike LASIK (Laser-Assisted In Situ Keratomileusis) eye surgery, which involves creating a flap in the cornea to access the underlying tissue, PRK eye surgery removes the thin outer layer of the cornea, called the epithelium. This makes it a suitable option for people with thinner or irregularly shaped corneas, or those who are not suitable candidates for LASIK surgery.

Let’s explore the basics of PRK eye surgery, its benefits and risks, and what to expect during the procedure.

How is it Performed?

PRK eye surgery is a two-step process that involves reshaping the cornea using an excimer laser. The first step is to remove the epithelium layer, which can be done through two methods:

• Traditional PRK: The surgeon will use a small surgical tool called a trephine or a brush to gently scrape off the epithelium.
• TransPRK (Trans-Epithelial PRK): This newer method uses the excimer laser to remove the epithelium layer, eliminating the need for a surgical tool.

After removing the epithelium, the surgeon will use a laser to reshape the cornea by precisely removing tissue in specific areas. This reshaping process is tailored to each individual's eye and their specific vision correction needs. Once the procedure is complete, a bandage contact lens is placed on the eye to promote healing.

Benefits of PRK Eye Surgery

• Suitable for those with thin or irregularly shaped corneas: PRK eye surgery does not require creating a flap in the cornea, making it an ideal option for people whose corneas are too thin or have an unusual shape.
• No risk of flap complications: Since there is no flap created during the procedure, there is no risk of flap-related complications such as displacement or infection.
• Permanent correction: PRK eye surgery permanently reshapes the cornea, providing long-lasting results. However, it should be noted that vision changes due to natural aging may still occur.

Conclusion

PRK eye surgery is a safe and effective procedure that has helped millions of people achieve better vision. It is important to consult with experts at UELC to determine if PRK is the best option for you based on your individual needs and medical history. With proper pre-operative preparation and post-operative care, most people can expect to have clear vision without glasses or contact lenses after PRK eye surgery.  So, if you are considering vision correction surgery, be sure to explore the option of PRK in Brampton and its potential benefits for you.  Remember to consult with your healthcare provider for personalized advice and guidance on making the best decision for your eyesight. Keep in mind that healthier eyes lead to a better quality of life!
