LASIK vision correction improves vision by permanently changing the shape of the cornea, the clear front window of the eye, so that images focus properly on the retina.
Traditionally, LASIK vision correction has been successful in measuring and correcting visual imperfections that cause myopia (nearsightedness), hyperopia (farsightedness) or regular astigmatism (blurriness). However, LASIK vision correction has been limited in its ability to measure and make corrections for more complex visual conditions such as irregular astigmatism, which may result in symptoms such as halos, ghosting of images and glare (usually worse at night).
Now there is an advanced method of measuring visual distortions (also known as aberrations) of the eye before LASIK vision correction to enhance visual outcomes afterwards. Using wavefront technology to make specific measurements of the eye before surgery, Dr. Reiff can now significantly reduce the occurrence of higher-order aberrations (including irregular astigmatism and spherical aberration) that can result in fewer visual side effects and improved quality of vision.
Dr. Reiff will map both of your eyes using a wavefront scanner, called an analyzer or aberrometer. This device produces a very precise, detailed map of light rays as they travel through your eye, highlighting imperfections in your vision.
A wavefront map of an eye with no visual errors appears to have a flat surface because all of the light rays travel evenly through the eye. A wavefront map of an eye with visual imperfections (aberrations) appears curved or distorted because some light rays reach the retina before others or strike different points on the retina.
By mapping both eyes using the wavefront analyzer, a very specific visual profile- often referred to as a visual "fingerprint"- is created for each eye. Dr. Reiff programs these unique profiles directly into the excimer laser used in surgery, customizing the procedure according to each eye's distinct vision correction needs.
- greater predictability of visual outcomes;
- reduced chance of higher-order aberrations that cause side effects such as haze and nighttime glare or halos around lights;
- increased chance of seeing better after refractive surgery than you did with eyeglasses or contacts before surgery;
- the potential for better results following surgery than if a conventional
(non wavefront-guided) refractive procedure had been performed.
In addition, patients who have experienced vision complications after previous refractive surgery have a greater chance of success during re-treatment using wavefront measurements.
A clinical study performed by the Federal Food and Drug Administration (FDA) reported that at one year after wavefront-guided treatment, 98% of participants could see 20/20, and 70% could see 20/16 or better without correction by glasses or contact lenses.
Bladeless LASIK In bladeless LASIK a femtosecond laser directs energy to create a thin flap on the eyes surface (cornea) instead of a mechanical cutting tool (microkeratome). Dr. Reiff uses computer software to guide the femtosecond laser resulting in a corneal flap created at a predetermined precise depth and diameter.
In patients where the cornea (front surface of eye) is not sufficiently thick enough to make a flap or the desired correction is too high to undergo LASIK, photorefractive keratectomy or PRK is a better alternative.
As with LASIK, Dr. Reiff uses the most advanced excimer laser technology available. With PRK, the front thin flap of corneal tissue is manually removed after which the narrow diameter laser beam removes tiny layers of cornea by breaking the bonds that link tissues together with only minimal effect on surrounding cornea. In fact, the beam only penetrates about two thousandths of an inch or about the thickness of a human hair but is enough to change a corneal curvature. In correcting far-sightedness the cornea is steepened and in correcting nearsightedness the cornea is flattened.
After PRK, the healing process replaces some of the tissues removed by the laser. As a result, during the first few days following PRK, while the eye heals and the surface cells smooth out, vision may be blurred compared to the almost immediate WOW effect of LASIK. But although healing is slower than LASIK, the end result is normally the same- clear vision without the aid of contact lens or glasses.
LASEK, or Laser Assisted Subepithelial Keratectomy, is a modification of the LASIK and PRK procedures. The cornea is bathed in a special solution, usually diluted alcohol. Then a thin flap of corneal tissue is lifted so the central cornea may be treated with the excimer laser. After treatment, the flap is replaced and allowed to heal. A contact lens is worn for a few days until recovery is complete.
As with PRK, LASEK may be a better alternative than LASIK in patients with thinner corneas, very high prescription contact lenses, or thick glasses.
The Visian ICL is a newly F.D.A. approved implantable contact lens. Dr. Reiff has the honor of being one of the first surgeons in the United States trained to perform this procedure. This revolutionary technology is unlike "LASER" refractive surgery in that the Visian ICL does not require cutting or removing tissue from the cornea (front surface of the eye). People that were previously not candidates for laser vision correction due to thin corneas, irregular corneas, and severe nearsightedness can now become less dependent on, or completely "throw away" their glasses and contacts. Also, because the implantable contact lens is removable and replaceable, you indefinitely retain your option to make future choices about your vision.
