Modern laser vision correction surgery has accomplished a remarkably great level of safety and accuracy. LASIK surgery is rapid and comfortable, and visual recovery is quick. As a bladeless procedure, LASIK has delivered amazing results to millions of people around the world. Our Hudson Valley area patients appreciate the great results driven by our expertise with these highly advanced technologies. In the past, patients with similar glasses prescriptions received the same surgery.

What is LASIK?
LASIK is the most popular form of laser vision correction. This laser vision correction procedure corrects myopia, hyperopia, and astigmatism. The surface of the cornea must be permanently reshaped to correct these vision problems. That’s where LASIK comes in.
During LASIK surgery, your surgeon uses a femtosecond laser to create a circular “flap” on the surface of the cornea. Once created, the flap is then pulled back to expose the inner layers of the cornea for treatment.
A second laser called an excimer laser removes microscopic amounts of corneal tissue to reshape the eye. Only the tiniest amount of tissue is removed from the cornea to achieve vision correction. Once the proper adjustments are made, the corneal flap is repositioned and left to heal on its own. No stitches are required after having LASIK surgery!
Why is LASIK a Bladeless Procedure?
Before LASIK was a bladeless procedure, it was performed using an instrument called a microkeratome. In traditional LASIK, the microkeratome cut the flap and reshaped the cornea.
With LASIK now, using a femtosecond laser and an excimer laser to create the flap and reshape the cornea makes it much more precise. This method of LASIK, known as Femtosecond LASIK, applies concentrated light energy to an exact depth within the cornea. Dr. Cheema then creates a layer of gas bubbles which creates the smooth and uniform flap and folds back the flap to reshape the cornea with the excimer laser.
It also lends itself to more reliable, exact results thanks to a smoother, more regular flap. That translates to a quicker and more efficient healing time for patients.
Dr. Cheema and his highly experienced team of eye care specialists perform Femtosecond LASIK.
SMILE stands for Small Incision Lenticule Extraction. SMILE is a laser procedure used to correct a patient’s vision. It’s similar to procedures like LASIK or PRK, but it has some key differences. Unlike LASIK or PRK, SMILE is minimally invasive and only requires a small incision in the eye. How is this possible?
The surgeon uses a femtosecond laser to remove a small, disc-shaped piece of corneal tissue. This is called a lenticule. Then a small incision is made to pull out the lenticule. This allows the surgeon to reshape the cornea to correct refractive errors. There’s no penetration with the surface of the eye, allowing for the most minimal amount of tissue damage possible.
PRK stands for photorefractive keratectomy. PRK is a laser vision correction surgery very much like LASIK. There are some differences, but PRK came before LASIK. In fact, PRK was the first kind of laser vision correction surgery made commercially available.
