What is PRK?
PRK (Photorefractive Keratectomy) is the first generation of Laser vision correction.
Corrects: Nearsightedness, Farsightedness, Astigmatism, Presbyopia.
How is PRK different from Lasik?
The main differences between the PRK Surgery and LASIK are the creation of a corneal flap in LASIK, and the recovery time and process.
The overall goal of PRK is the same as LASIK: to correct refractive errors and reduce dependency on glasses and contact lenses. PRK and LASIK both use a laser to reshape the cornea. Correct curvature allows the light entering the eye to focus correctly on the retina.
How does the procedure work?
Who is a candidate?
As with other laser vision correction procedures LASIK or SMILE, candidates for Photorefractive Keratectomy (PRK) should:
- Be 18 years of age or older
- Have a stable prescription
- Have healthy eyes free from a history of disease
PRK is typically the preferred procedure for patients who:
- Have thinner cornea with less amount of corneal tissue
- Are older – as our eyes age and change, PRK may become a better fit than LASIK
- Are active military personnel or in other professions that require PRK for refractive eye surgeries such as MMA or wrestling
- Have had previous refractive surgeries such as LASIK or other types of trauma to the cornea that make creating a flap risky
- Do not want a corneal flap
Recovery time
Most people return to work or normal activities within 3 to 5 days.
