Laser Vision Correction (LASIK)
LASIK (laser-assisted in situ keratomileusis) is a safe, reliable and painless way to improve vision and reduce or eliminate the need to wear glasses or contact lenses. LASIK changes the way light is bent, or refracted, as it passes through the cornea so that it focuses properly on the retina and objects can be seen clearly.

LASEK / PRK
LASEK, or Laser Assisted Subepithelial Keratomileusis, is a modification of the LASIK procedure. The eye is bathed in a special solution. Then a thin flap of corneal tissue is lifted so the central cornea may be treated with an excimer laser. After treatment the flap is replaced and allowed to heal. A contact lens may be worn for a few days until recovery is complete. More of the cornea is exposed for treatment than with LASIK, making LASEK a better choice for patients who require greater vision correction.
PRK or photorefractive keratectomy is one of the safest and most time-tested laser vision correction procedures available. Like LASIK, it reshapes the cornea to improve vision. In PRK the surgeon uses an excimer laser to vaporize a small amount from the top of the cornea. Unlike LASIK no flap is necessary. A small bandage contact lense is placed on the eye for about 3 or 4 days. Until the surface of the eye has healed.
With the advanced VISX Excimer Laser System and CustomVue, FDA studies have shown 98% of qualified patients achieved 20/20 vision without glasses. The risks of PRK are rare but can include infection, haze, slow healing, scarring, over- or under-correction of the visual condition, and development of astigmatism. In most cases with a careful follow-up it is very rare for patients to lose vision after PRK.
Refractive Lens Exchange
Refractive lens implantation. Using methods similar to those in cataract surgery, refractive lenses are implanted in place of the eye’s natural lens. The procedure use local anesthesia and take approximately 15-30 minutes. The new lens helps the patient focus better, allowing the patient to shift focus between distant and nearby objects.
Refractive Lens Exchange (RLE) is usually recommended to patients over 45 who wear bifocals. A standard implant replaces the natural lens with an artificial one that cannot “accommodate” (shift focus between distant and nearby objects). Exciting new multifocal and presbiopic correcting implants offer the potential to focus both near and distance without glasses.
ICLs (Implantable Contact Lens)
The Visian ICL™ by STAAR Surgical is an insertable contact lens used to correct myopia (nearsightedness) in adults aged 21-45 without altering the cornea. It is the only minimally-invasive foldable lens available in the U.S. Made of a patented collagen-containing material called collamer, the Visian ICL is highly biocompatible, meaning it can be implanted in the eye with minimal risk of rejection. Under topical anesthesia, the ICL and a gel-like substance is placed behind the iris through a tiny incision in the cornea. The gel is then removed. The procedure takes about 15 minutes and no stitches are required.
The ICL's location allows it to provide excellent quality of vision and also ensures that it is invisible to others. The ICL can be removed or replaced at any time, and patients can wear glasses or contact lenses or choose to have other procedures done with the ICL in place.
