Other methods of laser vision correction
PRK & LASEK  

PRK (Photo-Refractive Keratectomy)

You may be a candidate for Photo-Refractive Keratectomy (PRK) if you are not a LASIK candidate or do not wish to have LASIK done. PRK is a refractive procedure used to help create better vision for patients. In 1987, Dr. Marguerite McDonald, one of Dr. Martinez’ laser vision correction research mentors performed the first PRK on a seeing eye in the world. PRK was the first laser refractive surgery to be approved by the FDA in 1995. LSU, Dr. Donovan’s and Dr. Martinez’ training institution, was one of the centers for the FDA trial. In this procedure, an excimer laser is used to help reshape the cornea and improve nearsightedness, farsightedness, and astigmatism much like LASIK. PRK sets itself apartment from LASIK because no corneal flap is created. The first step of the procedure is for the surgeon to 'numb' the eye with a local anesthetic. After the eye has been successfully anesthetized, the surgeon places a diluted alcohol solution on the epithelium, the outer surface of the cornea. This outer layer is then lifted out of the way, and the excimer laser is used to make the necessary vision correction. Since the epithelium is removed during PRK the healing time is longer than with LASIK and there is more discomfort. However, there are circumstances such as when patients have thin corneas, when PRK may be a better alternative. The doctor will provide you with a list of post-operative care instruction following surgery. PRK can achieve the same level of vision correction as LASIK.

LASEK Long Beach
(Laser Epithelial Keratomileusis)

Laser Epithelial Keratomileusis (LASEK) is a procedure much like the first version of laser vision correction known as PRK. PRK (photorefractive keratectomy) was approved nearly a year earlier than LASIK, the most commonly known laser vision correction procedure. LASEK, like PRK, does not involve the surgeon creating a corneal flap Instead a thin layer of superficial cells is lifted and repositioned after the excimer laser is used to reshape the cornea. The healing time for LASEK is longer than LASIK because the treatment is performed on the surface of the eye. A contact lens may be placed in your eye to help begin the healing process. After the procedure, the doctor will provide you with a list of post-operative instructions.

LASEK is a strong alternative to LASIK and can provide great vision quality following surgery. Even though LASEK has a longer recovery time than LASIK, the post-operative results are essentially the same. Patients may choose to have LASEK rather than LASIK for a variety of reasons. If a patient has a thin cornea or if there is not enough corneal tissue or if LASIK is not a viable option then Dr. Martinez or Dr. Donovan may suggest LASEK or PRK.
