People with myopia, or nearsightedness, with or without astigmatism, and those with moderate amounts of hyperopia, or farsightedness, with or without astigmatism, are potential candidates for PRK. Your provider will ultimately determine if you are a good candidate for this treatment.
Potential candidates for PRK surgery must generally meet the following conditions:
- Be 18 years of age or older
- Have stable vision for at least one year prior to the time of surgery
- Have a full eye examination to rule out conditions that may contraindicate PRK surgery
- Have a refractive problem within the range of effective treatment
- Be fully informed of the benefits and possible complications following PRK surgery
- Not be currently taking certain medications that may be contraindications to PRK surgery
- Not be pregnant
If a patient does not meet these criteria, there is a good chance that they are not a candidate for PRK. There are also some pre-existing conditions that may complicate or prevent the treatment, including:
- systemic disorders such as diabetes, rheumatoid arthritis, or collagen vascular disease, which can cause corneal ulceration or melting
- ocular disease such as dry eye, keratoconus, or glaucoma
- a history of side effects from steroid use
- or, the use of certain drugs prescribed to treat migraines and acne
