Dr. Peter Hersh and the Cornea and Laser Eye Institute-Hersh Vision Group has extensive experience in the complete range of the many available procedures and technologies to surgically treat refractive disorders of the eye. Since beginning over two decades ago with the first clinical studies of laser vision correction, we have since treated thousands of patients with successful outcomes. Indeed, Dr. Hersh was lead author of the clinical trial which led to first FDA approval of laser vision correction in the United States. Our NJ LASIK and laser vision correction patients are encouraged to start here to learn more about the procedures offered at The Cornea and Laser Eye Institute, and then to schedule a free LASIK consultation to have their questions answered personally.
At the Cornea and Laser Eye Institute, vision correction candidates undergo a comprehensive and lengthy evaluation using sophisticated technologies to optimize results and eliminate patients with chances of a poor outcome. Using this evaluation, your individual needs can be matched to the proper procedure and laser technology to achieve the safest and best outcome.
Laser In Situ Keratomilieusis (LASIK)
LASIK is the most popular method of laser vision correction to treat nearsightedness, farsighteness, and astigmatism. In laser vision correction, an excimer laser produces a beam of light in which high energy is concentrated. The laser meticulously removes small amounts of tissue from the cornea. This reshapes the corneal surface, allowing it to better focus the image on the retina, with the goal of reducing a patient’s reliance on eyeglasses or contact lenses. In LASIK, the laser treatment is performed under a thin “flap” of the cornea which is created with a second laser, called a femtosecond laser. This differs from the LASEK/PRK procedure in which the laser treatment is performed on the surface of the cornea after the surface epithelial cells are removed. Vision generally is improved the day after LASIK.
Wavelight Allegretto Eye-Q Laser (Wavelight)
For LASIK at the Cornea and Laser Eye Institute, we use the Wavelight excimer laser, the latest state-of-the-art vision correction laser system. The Wavelight system uses a very small laser beam of less than 1 mm to shape the cornea. This beam is moved rapidly across the corneal surface in
a computer-controlled pattern of tiny overlapping spots. In addition, by measuring and correcting all eye movements during the laser procedure, the Wavelight system maintains accurate placement of the laser beam which provides additional control.
All-Laser LASIK (Intralase)
The Intralase laser is a new technology used to perform the first step in LASIK – the preparation of the corneal flap. Taking advantage of an advanced laser technique using a very short pulse, high speed femtosecond laser, the Intralase creates the flap in a uniquely precise mannner. The Intralase laser places over a million microscopic, low energy spots which split the cornea layers to prepare the flap to meticulous specifications with unsurpassed safety.
Topography-Guided LASIK (TG-LASIK)
In TG-LASIK, your individual corneal map is directly imported into the laser to help individualize and refine your LASIK contour. This is the newest innovation in LASIK and only available with the Wavelight laser. Not everyone is a candidate for TG-LASIK, but it can enhance results in many patient, especially those with irregular corneal contours.
Laser Epithelial Keratomileusis/Photorefractive Keratectomy (LASEK/PRK)
In this excimer laser procedure, the surface of the cornea is reshaped after the surface epithelial cells are removed. This differs from LASIK, in which the laser is applied beneath a corneal “flap”. Otherwise, the laser treatment is the same. Similarly, the goal of LASEK/PRK is to reduce a patient’s reliance on eyeglasses or contact lenses. LASEK/PRK may be advantageous in patient’s with thin corneas or corneal surface problems.
Reading Vision Correction
As you age, the lens within you eye becomes less able to focus and you begin to require reading glasses. Depending on you individual situtatio, there are a number of possible treatments to improve your near vision capabilities. First, some patients may be a candidate for LASIK blended vision. In this technique, one eye is tuned a little better for close vision and the other eye for distance vision. A new technique, the Kamra Corneal Inlay, is a small lens implanted within your cornea. This lens extends the range of your focus. Another procedure, Conductive Keratoplasty (CK), uses a high frequency, low power energy source to deliver electrical energy to the outer portion of the cornea to reshape the tissue. This steepens the cornea’s optical surface to better focus light and improve reading vision.
Phakic IOL (ICL)
The ICL is an artificial lens that is implanted into your eye to correct high degrees of nearsightedness. It is used for patients who are not candidates for LASIK or PRK, and some patients with Keratoconus.
This is non-laser procedure which may be helpful for patients with keratoconus or corneal optical irregularities after other surgeries. Intacs were originally FDA-approved to correct low degrees of nearsightedness, but have proven very successful over the years in treating some forms of keratoconus.
The Cornea and Laser Eye Institute is one of only a few centers in the region with specialized expertise in corneal transplantation. The goal of corneal transplantation is to restore sight to a patient whose cornea has been damaged by disease, injury, or inborn problems.
