Lasik and PRK

LASIK

LASIK, or Laser-Assisted in Situ Keratomileusis, is a type of laser eye surgery for correcting myopia, hyperopia, and astigmatism. In order for light to focus more clearly on the retina, the outer window of the eye, or cornea must be of the proper curvature.

A wide range of myopia, hyperopia, and astigmatism can be corrected by the LASIK procedure. It is a precise surgical procedure that allows for a very predictable healing response. Your vision stabilizes rapidly, and you can expect to have little or no discomfort following LASIK. Most patients have driving vision within 24 hours of treatment.

In preparation for the LASIK procedure a thorough examination of the eye is performed to determine if one is a candidate or not for the procedure. Typical pre-testing includes corneal topography, wavefront analysis, corneal thickness, and refraction.

Prior to performing the procedure, the eye is numbed with topical anesthetic drops. A corneal flap is then cut with either a microkeratome or a femtosecond laser such as IntraLase®.  The flap is then gently lifted, and the surgeon uses the computer-guided excimer laser to precisely reshape the cornea for corrected vision. The flap is replaced, and patients are instructed to keep their eyes shut for the next 2-4 hours, and to rest for the remainder of the day. The eyes are then examined the following day, and appropriate instructions are given at that time.

PRK

PRK (photorefractive keratectomy) is the same laser procedure as LASIK. It differs, however, in how the cornea is prepared for the laser treatment. With PRK, there is no creation of a flap and the surface cells are removed and the laser is applied. With LASIK, a corneal flap is created by a microkeratome or a femtosecond laser such as IntraLase®.

Today, PRK is commonly referred to as "surface ablation," meaning a laser procedure that is applied to the surface of the cornea. There are two main surface ablation techniques available which differ in the way the corneal epithelium is managed, LASEK and epi-LASIK.

In certain situations, PRK is a more suitable treatment option than Lasik.

  1. When the cornea is too thin for LASIK
  2. When a pre-existing problem is present on the cornea which can be eliminated with PRK and result in better vision than LASIK
  3. When there is a structural abnormality in the cornea that makes LASIK unsafe.
