The safer non-invasive laser vision correction performed exclusively by Dr. Emil Chynn at Park Avenue Lasek


What is SafeSight™?

It’s a type non-invasive laser vision correction performed by Dr. Emil Chynn at Park Avenue Lasek. People often think that all laser vision correction surgeries are the same, well they are not. Dr. Chynn performs LASEK, but he has a special protocol for preoperative exams, surgery and post op treatments! He actually patented and trademarked his way.

SafeSight™ is the name for a very advanced surface ablation procedure that includes a special post operative regiment that ensures the best possible visual outcome. Dr. Chynn personally performed over 15 000 SafeSight™ procedures and held numerous presprkentations about SafeSight™ on American and European congress.

Why is SafeSight™ non-invasive?
Because it’s non-cutting.  This means that no cut is made into your eye with a metal blade (as in LASIK) or with another cutting laser (as in IntraLase or i-LASIK).
zero flap complications!
Surface ablation is the only type of laser vision correction that can guarantee 0 (ZERO) flap complications! Because we won’t make a flap!
SafeSight™ is our term for Advanced Surface Ablation (the medical term) which is not PRK (the original way to perform laser vision correction, which was invented by two of Dr. Chynn’s colleagues when he was at Columbia Medical School (Drs. Stephen Trokel and Francis L’Esperance).

0% Of Flap Complications!

100% Satisfaction

Because it’s 100% non-cutting and 100% non-invasive, it’s 10x safer than LASIK.  With SafeSight™, none of the feared flap complications that may have kept you from getting LASIK is even possible–because we’re not cutting a flap to begin with!

SafeSight™ can treat astigmatism, far-sightedness and reading issues
Many people wanting to get rid of their contacts and glasses go to a LASIK center, but are rejected as good candidates.  They’re told that they cannot get LASIK or IntraLase because “You’re prescription is too high”, or “You’re cornea is too thin.”  This is not really telling the patient the full truth.

Your cornea has a thickness from 450 to 600 μm, SafeSight™ doesn’t create a flap like LASIK and saves corneal tissue, around 100-150 μm, that means we can treat more diopters than LASIK and still retain stability of your corena for your future. That also eliminates the risk of flap problems like night glare and halos, ghosting and reduces the risk of keratoconus.
Dr. Chynn performed SafeSight™ on a -22 D prescription. Possibly on one of the highest laser vision corrections in the USA. That patient now sees better than ever in her life using contacts or glasess.

SafeSight™ vs. LASIK

Why would you want SafeSight™ over LASIK?

Most other centers in Manhattan specialize in LASIK, or another version of LASIK called IntraLase or i-LASIK, in which the flap is cut with a laser.  IntraLase was developed to decrease the chance of complication while cutting the corneal flap.  And it works–the risk in IntraLase is less than the risk in LASIK.  However, you can never eliminate the risk of cutting a flap unless you actually stop cutting flaps–which Dr. Chynn stopped doing in 2005, when he introduced SafeSight™ to NYC!

In SafeSight™, instead of cutting your cornea in half to gain access, and lasering the back of your cornea, Dr. Chynn merely treats the front surface of your cornea–eliminating the need for the risky cutting step.  Fully 90% of all LASIK complications involve the flap, so by not making a flap, we’re eliminating 90% of all possible complications (including the most serious ones). So again, we can treat higher Rx, we can treat it safer and you will never have a flap complication.

SafeSight™ avoids the night glare and dry eyes that are sometimes associated with LASIK.  In fact, the primary reason that Dr. Chynn switched from performing (thousands) of LASIKs to SafeSight™ is that he himself has some minor (but bothersome) dry eyes and night glare after his own LASIK.

Night glare after LASIK is caused by your cornea being in 2 pieces forever, since the LASIK flap is cut, lifted up, put back down–and never fully heals.  This is why you can enhance a LASIK years later by digging the flap back up–because it never heals.  Because of this, after LASIK, light is invariably scattered and refracted by the flap interface.  Put another way, the “sandwich” configuration of your cornea is what causes backscatter of light.  This is most noticeable at night–and causes night glare.

Because your cornea is never cut and no flap is made in SafeSight™, night glare is avoided.  In fact, after SafeSight™, many of our patients say that their night vision is actually better than it was before in glasses or contacts!

Dry eyes after LASIK is also caused by cutting the flap. When this cut is made, most of the corneal nerves are cut–and never grow back. Your eyes are lubricated by the tear film, which is distributed when you blink. You blink when you (subconsciously) sense your eye drying out. This is why you cannot keep your eyes open forever–eventually, this sensation of dryness is so powerful, you cannot avoid blinking.

But what happens when you cut most of your corneal nerves? Published studies have shown that normal people blink every 5-10 seconds–but after LASIK, they blink only every 10-15 seconds.  In fact, they’re staring themselves dry without even knowing it!

Because SafeSight™ doesn’t cut your cornea and its nerves, your blink rate afterwards is the same as a normal, unoperated eye–hence, no dry eyes!

only glass open operating room in nyc!
Dr. Chynn has also eliminated all complications in the operating room by no longer cutting flaps.  That’s why we can have the only glass “open OR” in NYC! Do you think we could have people watching on the sidewalk during their lunch, invite companions into the OR, and stream our live LASEK seminars live if there was even a small chance of a major complication?  Of course not!
SafeSight™ for fixing LASIK complications
Your surgeon says you cant have an enhancement because now your cornea is to thin…

Well we helped many people in that situation. After your initial consutlation we can create a PreVUE lens on our laser with the prescription we can laser into your cornea and you will be able to expirence how your new vision will be. We had great success fixing LASIK sub-optimal outcomes with LASEK on top of the old LASIK flap, which almost always improve the vision, about 99% back to 20/20, 1% to only 20/25, and 40% to actually BETTER than 20/20″

SafeSight™ for lazy eye
In 2013. Dr. Chynn gave a lecture at ASCRS and showed results proving that adult lazy eye patients benefit from SafeSight™:

Doctors thought that parts of the brain that didn’t develop fully in childhood could never become active. They were pretty wrong because the brain is plastic, and it is much more plastic than researchers previously thought. If you are an adult with a “lazy eye” that you would like to fix, or at least know what is the ultimate potential for vision, you owe it to yourself to come to Park Avenue Laser Vision.
