Vision Correction Procedure Hits a Milestone Aug 13, 2008
"Laser refractive surgery has gone through an amazing evolution since the technology was first developed in the 1980s. Ten years ago there were only two laser refractive procedures available to consumers in the United States, PRK (Photorefractive Keratectomy) and traditional LASIK (Laser in situ Keratomileusis)," says Dr. Smith. "Over the years, as newer technology has won FDA approval, laser vision correction has become available to a broader segment of the population. Today, more people are... (Pekin Times, IL)
Lasik alternatives May 2, 2008
It goes by two names: Surface ablation, or wavefront-guided PRK, which stands for photorefractive keratectomy. What's most important is that it doesn't require cutting a flap into the cornea, the eye's clear covering, like Lasik does, a cut widely considered that procedure's riskiest step.

Scientists discover who is likely to get dry eye syndrome after LASIK surgery Mar 4, 2008
According to Dartt, the next steps for her team include expanding this study to a larger number of individuals and examining patients who have the PRK (photorefractive keratectomy) type of refractive surgery. The PRK has the same goal as LASIK, but the procedures differ. (EurekAlert!)
The Evolution of LASIK Opens Door for Patients With Vision Problems Jan 23, 2007
Lasik and the second-most popular procedure - PRK, or photorefractive keratectomy - are designed to correct three refractive errors: nearsightedness; farsightedness; and astigmatism, a visual distortion that causes blurred vision. KATHERINE FREY/THE WASHINGTON POST After having elective LASIK surgery in both eyes, Alice Corbett no longer needs glasses for distance, though she still uses them for reading. (The Ledger)
Lasik Vs. Lasek: Both Are Safe, Effective Dec 30, 2006
Lasek (laser-assisted subepithelial keratectomy) cuts only the outside surface of the cornea. This avoids some of the flap problems that can come with the deeper cut made during Lasik (laser in situ keratomileusis). (CBS News)
Laser Eye Surgery: 10 Years Later Nov 15, 2006
A team of researchers from Spain tracked LASIK surgery (laser in-situ keratomileusis) and its forerunner, PRK (photorefractive keratectomy). In both procedures, the cornea is reshaped so that light entering the eye focuses on the retina in the back of the eye, as it does in those with normal vision. (CBS News)
Innovative surgery corrects vision in kids with neurological disorders Oct 11, 2006
Tychsen and his staff perform laser-assisted subepithelial keratectomy, or LASEK, in which the cornea is reshaped with a laser. This technique doesn't require a surgical flap to be cut in the eye and is safer for children, who will inevitably rub their eyes after surgery. (EurekAlert!)
Cornea supply may grow Jul 3, 2006
Patients with LASIK or PRK (photorefractive keratectomy) eye surgery have not been candidates for cornea donation because of the transplantation method, but a new surgical technique will change the restriction, said Olkowski, EyeSight Hawaii refractive and corneal specialist. Olkowski said he had to cancel three corneal surgeries scheduled two weeks ago because no corneas were available. (Honolulu Star-Bulletin)
Two Laser Vision Surgeries Work Equally Well Apr 22, 2006
Both LASIK (laser-assisted in-situ keratomileusis) and PRK (photorefractive keratectomy) use a laser to reshape the eye's cornea. PRK works by shaving off microscopic layers of the cornea. (MEDLINEplus)
Two Surgeries For Nearsightedness Equally Effective, Review Says Apr 21, 2006
LASIK (laser-assisted in-situ keratomileusis) and PRK (photorefractive keratectomy) both use a laser to reshape the eye's cornea, which helps to focus incoming light, in people with nearsightedness. With PRK, the cornea is reshaped by using the laser to gently shave off microscopic layers of the cornea. (Science Daily)
