PRK reshapes the cornea from the surface without creating a flap, correcting your focusing so you rely less on glasses or contact lenses.
What is PRK?
PRK (photorefractive keratectomy) and the closely related LASEK are surface laser treatments. The thin outer layer of the cornea (epithelium) is gently removed or moved aside, an excimer laser reshapes the surface, and the epithelium regrows over the following days. There is no corneal flap.
Who is PRK suitable for?
PRK and LASEK are often recommended for people with thinner corneas, certain prescriptions, or higher-risk lifestyles such as some sports or occupations where a flap-based procedure is less ideal. A full corneal assessment determines the best option.
Recovery after PRK
Vision settles over one to two weeks as the surface heals, which takes a little longer than LASIK or SMILE. A protective contact lens and lubricating drops are used in the first few days.
PRK cost
PRK usually costs £800–£2,000 per eye in the UK, including your assessment, the treatment and follow-up appointments, with 0% finance widely available. See our PRK cost guide for a full breakdown.
Not sure whether PRK or a lens-based option is right for you?
Register your interestThe lens-based alternative if you are over 45
Laser reshapes the cornea and does not stop age-related focusing loss (presbyopia) or future cataracts. If you are over 45, refractive lens exchange replaces the natural lens with a multifocal implant — correcting distance, intermediate and near vision and preventing future cataracts. It is consultant-led at our South England clinics from £4,300 per eye. Compare lens replacement (RLE).
