Other procedures - PRK, ICL, Refractive Lens Exchange

Currently, LASIK is the principle procedure worldwide for surgically correcting the refractive errors. However, LASIK has its limitations and is not the procedure of choice for every patient who is nearsighted or farsighted.

Typically, patients with very high levels of myopia or hyperopia are better candidates for other surgical methods. Among others, factors like corneal thickness and the probability of side effects when correcting high refractive errors with LASIK may favor other routine methods carried out at the Laser-Vision-Center Lohr. Results indicate that for higher levels of refractive conditions, the quality of vision for patients is better than that seen with LASIK.



PRK (Photorefractive keratectomy) was the original excimer laser procedure to be approved by the FDA in 1995. However, unlike LASIK, the outermost surface layer of the cornea (the epithelium) is removed first and then the laser is used to reshape the cornea.

LASEK (laser epithelial keratomileusis) is a technical variation of PRK. With LASEK, the outer layer of the cornea is first loosened by covering the surface with the alcohol for approximately 30 seconds. Then the surgeon, using special instrumentation, peels back the surface layer exposing the underlying cornea to the laser beam.

Both methods have a longer healing process than LASIK and vision is not restored as quickly with PRK as in LASIK. There are some individuals who are not candidates for LASIK but may be candidates for PRK or LASEK.



An Intraocular Contact Lens (Visian ICL) is a lens implant that is placed within the eye solely for refractive purposes. The natural crystalline lens of the human eye remains in place. The main attraction of this procedure is that no tissue is removed from the eye and it is potentially reversible the implant can always be removed or exchanged.

The surgeon inserts the artificial lens through a small incision. It is carefully positioned behind the cornea, but in front of the eyes natural lens. This small incision is usually designed to be self-sealing and completed without stitches. Implantable lenses are manufactured of materials that are biocompatible, so they can rest within the eye without need of care.

IOL or Refractive Lens Exchange (RLE)

Refractive Lens Exchange

In contrast, during a Refractive Lens Exchange an Intra-ocular Lens (IOL) takes the place of the natural human lens. The natural lens is removed using ultrasound to break up the lens in the eye. This procedure is called phacoemulsification.

Prior to surgery, specific measurements of your eye will be taken to determine the power of the implant to be placed in the eye. The implant power is very critical in that it will determine whether you need to wear glasses for distance or reading after surgery. We use a no-stitch technique that usually requires no patching of the eye.

As a patient, you can begin using the eye immediately after surgery. The procedure takes approximately 10 minutes and, quite like the LASIK method, done on an ambulatory basis. Phacoemulsification is also a routine method during Cataract surgery, one of the most often performed surgeries at all.
