LASIK Laser Vision Correction

How Does LASIK Work?

LASIK Brooklyn NYLASIK is the most advanced laser vision correction procedure available today, and Dr. Koster is one of the best qualified refractive surgeons in New York City, having over 20 years of refractive surgery experience.  He was the surgeon director of the SUNY College of Optometry Laser Center for over ten years, and now runs his own laser center,  where he specializes in premium LASIK.

For his LASIK patients, Dr. Koster utilizes the WaveLightt® EX 500 Laser, the most technologically advanced vision correction laser available in the U.S.  This laser is conveniently located in his own laser suite at 37 Murray Street in Manhattan.  The WaveLight® EX 500 Laser allows us to provide a customized treatment for each patient's eyes.

LASIK is now a mature, extremely safe procedure, initially approved by the FDA in 1998.  LASIK stands for “laser in-situ keratomileusis,” which means to treat the cornea with a laser. It is an essentially  painless procedure that may eliminate the need for glasses or contacts forever. During LASIK eye surgery, pulses of cool laser from a precisely calibrated laser reshape the surface of the cornea. This allows images to focus more directly on the retina, and permits images to come into better focus.

How well you see without glasses depends on the shape of your cornea—the eye’s clear covering. Generally speaking, in nearsighted people, the cornea is too curved. Conversely, in farsighted people, the cornea is too flat. And, people with astigmatism generally have an oval shaped cornea. Each of these different irregularities in the shape of the cornea adversely affects a patient’s vision, and each of these irregularities can be corrected by LASIK.

In the case of nearsightedness (also known as myopia), LASIK’s laser pulses flatten the cornea slightly, permitting incoming light rights to better focus

In the case of farsightedness (also known as hyperopia), LASIK’s laser pulses gently steepen the cornea

Finally, in the case of astigmatism, LASIK rounds out the cornea.


Who is a Candidate?

The ideal candidate for LASIK has stable refractive error within the correctable range, healthy eyes, is at least 18 years old and is willing to accept the potential risks and side effects of LASIK. You can find out if you are a candidate for LASIK by having a consultation with us and by taking our Self Evaluation Test online. Prior to the procedure, all LASIK patients at NY Vision Group must undergo an extensive pre-operative evaluation in either our Manhattan, Queens or Brooklyn offices to determine whether LASIK is an appropriate option for them.


The LASIK Procedure

LASIK Surgery New York

The LASIK procedure consists of two parts. First a thin layer of cornea (called the cornea flap) is created either by a delicate instrument called a microkeratome that glides across the cornea or by a femtolaser. Then, after lifting the flap, the surgeon focuses the exicmer laser beam over the eye, and, in usually less than 60 seconds, applies cool ultraviolet laser pulses from an excimer laser. These laser pulses reshape the internal cornea with an accuracy of 1/2500 of a millimeter. After the laser treatment portion of the procedure is completed, the cornea flap is replaced and naturally adheres in place.

At NY Vision Group, patients have the choice of using the Moria SBK keratome, which delicately and mechanically creates thin flaps, or the FEMTO LDV laser, which creates the flap using ultra short laser pulses to gently separate the layers of the cornea, also creating very thin flaps.  Both options utlize the lasest technology.

The procedure is performed using topical anesthetic eye drops and takes less than 5 minutes per eye. There is no pain during the procedure, and patients are awake and comfortable during the whole process. The vast majority of patients see a dramatic improvement in their vision immediately following the surgery, followed by continued improvement over the next few days.  For a small group of patients, however, vision may be blurry and fluctuate for a week or more. Patients are given protective shields to wear immediately following the procedure and at bedtime, however, the eye does not need to be patched. There is minimal discomfort during the overnight recovery period, and most patients return to work within a day or two. And, in a vast majority of LASIK patients, the visual outcome is excellent. Nonetheless LASIK is surgery and every precaution should be taken to ensure a safe and healthy result. Dr. Koster will review the risks, benefits and alternatives of the procedure with patients prior to the procedure. Patients should study and explore their options carefully, ask the doctors and staff at NY Vision Group any questions they have, and if they do choose to have LASIK, diligently follow all pre-operative and post-operative instructions. 

Dr. Koster and NY Vision Group have access to all the major laser platforms, including the WaveLight laser systems by Alcon, the VISX laser by AMO and the Technolas eximer laser by Bausch & Lomb.  However, based on his 20 years of refractive surgery experience, Dr. Koster has determined that the WaveLight® EX 500 Laser provides the best treatment options for his patients.  His practice is the first practice in Manhattan to acquire the WaveLight® EX 500. the mos. 

The combination of the WaveLight's superior technology and Dr. Koster's many years of experience assure the best care possible for our patients.
