Before any eye surgery such as custom LASIK vision correction is considered, basic education about the eye tends to be helpful for our patients. Here is a quick primer on your eyes and how they work.

All vision is based on light. In order for you to see correctly, light must pass through various parts of your eye for your brain to interpret what you are seeing and produce an image of the object you are looking at. To see clearly, the cornea (the front of your eye) must be perfectly round. When light passes into the cornea, it passes through the iris, the pupil, and finally, the crystalline lens, located inside of the eye. Depending on the amount of light, the pupil and the iris muscles adjust to allow the proper amount of light in. After passing through the iris and the pupil, the crystalline lens focuses the light onto the retina. The retina senses different types of light and allows the optic nerve to send the information to the brain.

Clear Advantage Vision Correction Center was the FIRST center in Northern New England offering an"all laser," blade-free, LASIK procedure. In fact, the DaVinci Femtosecond laser is one of the newest, and most advanced bladeless lasers on the market today. In traditional LASIK surgery, a thin flap in the cornea is created by a microkeratome (a mechanical device with a precise, sharp blade).

The DaVinci Femtosecond laser solves the"flap creation with a blade" by using an extraordinarily fast and ultra precise laser that essentially creates millions of air bubbles in the cornea that overlap creating a"bubble" on the front of the eye, which is then gently lifted. Bladeless treatments are a great alternative for patients who previously were unable to get LASIK due to thin corneas or dry eyes.  Due to the significant safety of bladeless LASIK over traditional bladed procedures, Clear Advantage only offers LASIK, Advanced LASIK and Customized LASIK treatments using bladeless flap creation.

"I am writing this less than 24 hours after the procedure, and I'm thrilled with the results. I was very nervous, as I am about any medical procedure, but the staff and doctors could not have made the experience better. It was painless, fast and everyone made me comfortable. And the results are amazing. Thank you, thank you, thank you."
