PhotoTherapeutic Keratectomy is a type of laser eye surgery used for a range of problems affecting the superficial layers of the cornea. PTK uses the same excimer laser as in LASIK, LASEK or TransPRK. Instead of reshaping the cornea to correct your vision, PTK can remove scars, opacities or treats painful recurrent erosions.
If you already wear glasses or contact lenses and need to have a therapeutic laser treatment it may be possible to correct your vision simultaneously. As an alternative to PTK, PhotoRefractive Keratectomy (PRK) can, in selected cases, correct short-sightedness (including astigmatism) in addition to the primary therapeutic goal.
PTK treatment is normally covered by insurers; PRK, LASEK & TranPRK are not covered.
This is possible in some patients, depending on the underlying need for treatment and your existing spectacle prescription. Because scars or surface irregularity can affect the accuracy of laser treatment, Mr Gore may advise a two-step plan if you’re keen to additionally correct your short-sightedness: PTK to treat the initial problem, then a few months later PhotoRefractive Keratectomy (PRK) to get rid of glasses.
PTK treatment is normally covered by insurers; PRK is not covered.
