Our Deer Park Location

From the Long Island Expressway, visitors should exit Deer Park Avenue and travel south. Make a right onto Nicolls Road, and we are located on the left hand side before the intersection with 1st Street. Our office is next to Deer Park High School and not far from Robert Frost Middle School.

SightMD is actively involved in the Deer Park community, and recent events we have attended include the North Babylon Community Festival & Street Fair, the East Islip Community Fair, and the Islip Main Street Fall Festival. We believe strongly in the importance of patient education, and we take each opportunity we can to engage with the community of Deer Park.

Our Services

We offer many different services at our Deer Park facility, including:

  • LASIK – We are proud to offer bladeless iLASIK, an innovative procedure that is highly customized to your unique visual errors. We use the most advanced technology and maintain a precisely controlled environment to provide optimal LASIK results.
  • Cataract Treatment – In order to help patients suffering from the effects of cataracts, we offer laser cataract surgery. During this procedure, your doctor can remove the clouded lens and implant an intraocular lense (IOL) to provide you with renewed vision.
  • iDesign Technology – Abbott’s iDesign system allows us to precisely understand the unique contours of your eyes so that we can accurately assess your candidacy for refractive surgery.
  • Treatment of Corneal Conditions – The clear surface of your eye can be affected by various corneal conditions. We provide effective corneal treatment options, including a corneal transplant procedure that involves using donor tissue to restore lost vision.
  • Glaucoma Treatment – Glaucoma involves abnormally high eye pressure, which can cause damage to the optic nerve and compromise your vision. Our specialists offer both surgical and non-surgical glaucoma treatment options to help protect your eye health.

I've just completed final post op checkup after two cataract removals by Dr. Van. Everything is as good as one could expect and I am grateful but not surprised. That has been my experience with Dr. Van over the many years she has taken care of my eyes.The warmth and efficiency of her staff has always been appreciated.I would recommend Dr. Van without reservation.Vincent Maroney

This is my second visit with Dr. Faye Knoll. I had been seeing another Dr. for two months and just felt I needed to see a new Doctor. Dr. Knoll had a great bed side manner. She listens to you and addresses your concerns without making you feel like you shouldnt be asking questions. She spends some time with you so you dont feel after 5 mins your time is up & I must move on.. I finally feel at peace with my eye condition and can see the light at the end of the tunnel. Dr. Knoll makes it clear that if there are any changes with my eyes that I should call her! The other Dr. never stated that and you could never reach a person at his office. Also, the staff are not the friendliest. The staff at Sight MD have all been very helpful and always available! I have not needed to reach out to Dr. Knoll through the call center as of yet but Im hoping that if I ever do, I will have success. My other Dr. had me on a medication for two months that I should have only been on for two weeks! And he was going to keep me on the medication & add a steroid. I am so HAPPY I found Dr. Knoll! I wish I found her two months ago.. I probably would have been Ok by now, if I did! I highly recommend Dr. knoll and she now has two new patients me and my husband. Thank You Dr. Knoll and please dont change.. You are a asset to the world of Opthalmology !

I won't say why I see Dr. Knoll, but she has always been professional, polite and friendly with me, and has handled difficult situations smoothly. I first encountered her several years ago while she was still training; the person training her, Dr. Ira Udell, clearly still holds her in high regard. A few years later when I needed to see someone with her skills, and found her where another family member goes, she became the go-to person for me for certain issues. I most recently saw her days ago, and as usual I received a careful, thorough exam, with well thought out plans on how to move forward. I will note that I prefer to see her at the Deer Park office - it is far more relaxed and easy to deal with.

Within a period of a couple months I went from an eye infection from my contact lenses to LASIK surgery. My first time at North Shore eye care was an emergency visit. I had no appointment but I called them and they fit me into Dr. knoll's busy schedule. The staff is very friendly, I've been to 5 of their offices. Wait time is never that bad except for maybe once out of over 10 appointments. Dr. Knoll performed my surgery and I have nothing but positive things to say about her. She tells you what she's doing step by step during the surgery. They offer free LASIK consultations and 2 year no interest financing with a carecredit card (super easy to sign up for online, takes less than 5 min).
