What is LASIK?

LASIK stands for laser-assisted in-situ keratomileusis which means to treat the cornea with a laser. It is a highly effective laser procedure used to correct vision problems such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism and is suitable for most low, moderate, and high prescriptions.

LASIK eye surgery was first performed in the United States in 1991 and was formally approved by the FDA in 1998. The procedure has quickly grown to be the most popular type of elective surgery in the world, with more than 28 million procedures performed.

LASIK is a two-step procedure that uses advanced laser technology to reshape the cornea, the clear front part of the eye. The purpose of the cornea is to bend (refract) light so it can reach the retina and be transmitted to the brain as visual information.

Some people have corneas that are irregularly shaped, which causes light to focus in front of the retina instead of on it. This results in blurry vision at varying distances, or what’s known as a refractive error. Refractive errors include nearsightedness, farsightedness, or astigmatism, all of which can be corrected during LASIK. As light enters the eye, the curve of the outer window, the cornea, bends it. If the cornea is too curved or too flat, the light will not be in focus on the retina at the back of the eye. LASIK permanently changes the curve of the cornea so that patients can see well with freedom from contacts or glasses.

NY Vision Group utilizes the WaveLight Ex 500 Laser, the most technologically advanced vision correction laser for all of its LASIK patients. In fact, NY Vision Group was the first practice in NYC to obtain this technology, giving us the longest experience with this laser. The laser uses wavefront technology to provide a customized treatment for each patient’s eyes. Wavefront technology is a combination of special software and equipment used to electronically scan a patient’s eyes before surgery. Each scan creates a highly detailed digital map of the cornea which is then used during treatment to customize the vision correction for the unique characteristics of each patient’s eye.

Am I a candidate for LASIK?

Young couple enjoying the view after LASIKAlthough LASIK is one of the most advanced vision correction procedures available today, LASIK is still a surgical procedure. As such, all potential patients must undergo extensive pre-operative evaluation in either our Manhattan, Queens or Brooklyn office to determine if LASIK is an appropriate option. Furthermore, potential candidates must understand the benefits and risks of the procedure and have realistic expectations about the potential outcome.

If Dr. Harry Koster or one of our other refractive surgeon determines that LASIK is not the procedure that best suits your needs, other procedures such as PRK, Refractive Lens Exchange, or phakic implant surgery, may be more appropriate for you. We can discuss each of these options with you and give you a fair estimate of the results you could achieve with them. You can begin the process of determining if you are a candidate by taking our LASIK self-test.

The Best Candidates for LASIK are:

  • 18 years of age or older;
  • have a stable prescription for the last year or two;
  • have healthy eyes;
  • have a sufficiently thick cornea, with normal curve and tear film ;
  • have realistic expectations about the surgery’s outcomes and are willing to accept the potential risks, complications and side effects of the procedure;
  • if wearing contact lens, discontinue use several days prior to the examination, (time depending on the type of contact lenses.)

What happens before LASIK?

At NY Vision, we start by scheduling an initial evaluation with one of our board-certified LASIK surgeons to determine your candidacy. If you wear contact lenses, we will, for some days, request that you stop wearing contact lenses before the appointment.

During your appointment, you will be asked about your medical history, current medications, and allergies. A thorough exam will also be conducted to assess your prescription, corneal thickness, and shape, as well as your overall eye health. The surgeon will discuss the risks, benefits, and expectations for LASIK, as well as answer any questions you may have.

If you are approved as a candidate for LASIK, you will be asked to stop using cosmetics the day before surgery. It’s also important to arrange for transportation to and from your surgery, as well as your follow-up visit.

What happens during LASIK?

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. A thin hinged flap of the cornea is created, which is lifted back.

Once the flap is lifted, the surgeon applies a cool beam of light from the laser to reshape the cornea and correct the refractive error.

Finally, the corneal flap is positioned back into place. No stitches or sutures are necessary, as the flap fuses with the eye to act as a natural bandage.

What happens after LASIK?

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. A few patients experience dry eyes, sensitivity to light, or general irritation after LASIK, but these symptoms should improve within the first few days after surgery. Your doctor can prescribe eye drops or recommend a pain reliever to help with recovery.

It’s important not to rub your eyes, play contact sports, or wear makeup around the eyes immediately after LASIK. Your eyes need time to heal.

A follow-up visit will be scheduled after surgery and at regular intervals after that. Keeping your follow up appointments is important. In the vast majority of patients, the visual outcome is excellent. Nonetheless, LASIK is surgery and every precaution should be taken to ensure a safe and healthy result. The doctors at NY Vision Group will review the risks, benefits, and alternatives of LASIK with patients prior to the procedure. Patients should evaluate their options carefully, ask any questions they have, and if they do choose to have LASIK, follow all pre-operative and post-operative instructions.

Are there alternatives to LASIK?

If you are not a candidate for LASIK, there are other options available. We offer PRK and Epi-LASIK, LASEK, Refractive Lens Exchange (RLE) and premium lens implants. Dr. Koster and the staff at NY Vision Group will help decide which procedure is best for your vision and lifestyle.


Although LASIK is not typically covered by insurance, some insurance plans may cover part of the procedure or offer a discount. NY Vision Group will work with you to determine the status of your insurance coverage and to find a financing solution that fits your needs. We offer flexible, low monthly payment financing through Wells Fargo and Care Credit.
