PRK Surgery (Photorefractive Keratectomy)

Myopia, also known as nearsightedness, is a common type of refractive error where near objects appear clearly, but far objects appear blurry. This happens when the eyeball is too long or the cornea has too much curvature, causing light to focus in front of the retina instead of directly on it.

Astigmatism causes your vision to be blurred at both near and far distances. It occurs when your cornea is shaped more like a football than a basketball.

Key features of astigmatism include:

1. Blurred or Distorted Vision: Individuals with astigmatism often experience blurred or distorted vision at both near and far distances.
2. Eye Strain and Discomfort: Astigmatism can lead to eye strain, headaches, and discomfort, especially after prolonged periods of reading or computer use.
3. Difficulty with Night Vision: Some people with astigmatism may notice challenges with night vision, including glare and halos around lights.
4. Combination with Other Refractive Errors: Astigmatism can occur on its own or in combination with nearsightedness or farsightedness.

The medical term for farsightedness is hyperopia. Farsightedness is a common refractive error in the eye that affects the ability to see close-up objects. In farsighted individuals, light entering the eye focuses behind the retina instead of directly on it. This can result from an eyeball that is too short or a cornea that has too little curvature.

PRK Surgery (Photorefractive Keratectomy) is typically recommended for people with thin corneas and provides visual results that are very similar to LASIK and SMILE. Your NVISION surgeon will determine which laser vision correction procedure is right for your individual needs based on your eye exam and your visual goals.

The PRK surgery (Photorefractive Keratectomy) procedure itself typically takes about 5 to 15 minutes per eye. However, the overall time spent at the surgical facility will be longer due to pre-operative preparations and post-operative care.

Just as with LASIK, PRK surgery is a procedure to help people with nearsightedness, farsightedness, and astigmatism. But every patient is different, and your NVISION surgeon will select the best procedure for your needs.

PRK (Photorefractive Keratectomy) eye surgery is generally considered safe and has been performed successfully on millions of individuals worldwide. Like any surgical procedure, PRK carries some risks and potential complications, but serious complications leading to permanent vision loss are extremely rare. The safety and success of PRK depend on several factors:

1. Patient Selection: The suitability of PRK for an individual depends on factors such as the degree of refractive error, corneal thickness, overall eye health, and lifestyle considerations. A comprehensive pre-operative evaluation helps determine if a person is a good candidate for PRK.

2. Surgeon Experience: The skill and experience of the refractive surgeon play a crucial role in the safety and success of PRK. Choosing a qualified and experienced surgeon with a track record of performing PRK procedures is important.

3. Technology and Techniques: Advances in laser technology and surgical techniques have contributed to the safety and precision of PRK. Customized treatments, such as topography-guided PRK, can enhance outcomes and reduce the risk of complications.

4. Post-operative Care: Following post-operative care instructions is essential for a successful recovery. Patients are typically prescribed medicated eye drops and given guidelines to minimize the risk of infection, manage dry eyes, and promote optimal healing.

5. Patient Compliance: Adhering to post-operative care instructions, attending follow-up appointments, and reporting any unusual symptoms to the surgeon contribute to the overall safety of PRK.

While PRK is considered safe for the majority of patients, it’s important to acknowledge that individual responses can vary. Some common side effects after PRK include temporary discomfort, light sensitivity, and fluctuations in vision during the healing process.

Before deciding on PRK or any refractive surgery, individuals should undergo a thorough consultation with an experienced refractive surgeon. During this consultation, the surgeon will assess candidacy, discuss potential risks, and provide personalized recommendations based on the individual’s eye health and lifestyle. As with any medical procedure, informed decision-making is key to a positive outcome.
