2024年11月8日 · With PRK, your ophthalmologist uses a laser to change the shape of your cornea. This improves the way light rays are focused on the retina. PRK is used to treat myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. The goal of photorefractive keratectomy is to correct your refractive error to improve your vision.

2024年1月10日 · Also known as PRK, this type of laser eye surgery can help if you are nearsighted, farsighted, or have astigmatism. It works best if your eye problem is mild or moderate. All laser vision...

Photorefractive keratectomy (PRK) is a laser eye surgery similar to LASIK. Unlike LASIK, which involves opening a flap in your cornea, PRK removes your cornea so that it grows back naturally. That makes it a better laser eye surgery choice for some people who can’t undergo LASIK.

2024年7月22日 · Photorefractive keratectomy (PRK) is a type of laser eye surgery that improves vision by correcting refractive errors.

Photorefractive keratectomy (PRK) and laser-assisted sub-epithelial keratectomy (or laser epithelial keratomileusis[1]) (LASEK) are laser eye surgery procedures intended to correct a person's vision, reducing dependency on glasses or contact lenses.

Photorefractive Keratectomy, or PRK, is designed to correct nearsightedness (myopia), farsightedness (hyperopia), and astigmatism by using an excimer laser to reshape the cornea without creating a flap in the cornea. PRK was the first kind of corrective eye surgery to use a laser rather than a blade to remove corneal tissue.

2020年8月12日 · PRK (photorefractive keratectomy) is a laser eye surgery that corrects refractive vision errors by changing the shape of the cornea. The cornea is responsible for refracting (or bending) light toward the center of the retina, and refractive errors happen when the shape of the cornea causes the refraction to be off-center.

2024年5月8日 · PRK works by reshaping the cornea, the transparent front part of your eye. This helps improve how the eye bends light and can reduce blurry vision. This article explains PRK surgery, including the procedure, recovery, effectiveness, and risks.

As the first refractive procedure approved by the FDA, PRK eye surgery is a tried and true vision correction alternative that continues to help patients reach their vision potential. Before LASIK, PRK was the refractive procedure that doctors and patients trusted.

With PRK, surgeons use state-of-the-art computer technology in combination with the accuracy and precision of the excimer laser to treat a wide range of nearsightedness, farsightedness, and astigmatism.
