    What is Photorefractive Keratectomy ?

    Understanding About

    Photorefractive Keratectomy

    PRK is a laser refractive procedure developed in 1983 by Dr. Steven Trokel and colleagues, with the first procedure performed in 1987 by Dr. Theo Seiler in Berlin. It involves ablating the corneal stroma to correct refractive errors such as myopia, hyperopia, and astigmatism.

    PRK received FDA approval in 1996 and was initially preferred over incisional keratotomy for its predictability and stability. However, its popularity declined in the late 1990s with the rise of LASIK.

     Despite LASIK being the most commonly performed visual refractive surgery today, there are still specific situations where PRK may be preferred.

    Photorefractive Keratectomy FAQS

    Photorefractive Keratectomy
    PRK is a good choice for more patients than LASIK, but recovery from PRK does take longer. Patients who choose either procedure enjoy excellent results and long-term vision correction.
    Like LASIK, PRK is a permanent adjustment to the eye’s optics. Over time, aging introduces changes in your vision that can be addressed by repeat surgery.
    As your vision changes over time due to aging, you may find that you’d like to have additional PRK correction, and you can do that. At some point you may need reading glasses as well, though.
    Recovery from PRK takes longer than LASIK, which can take less than a week. PRK recovery is usually a minimum of one to three months. Full vision stabilization can take as much as six months to a year. During the stabilization time, your eye doctor can provide correction options like glasses to help with driving and other visually demanding tasks.
    Yes, PRK is considered better for patients with chronically dry eyes. In fact, LASIK is usually not recommended for people with severe chronic dry eye.
