How It Works


How Does LASIK Work?

Under ideal conditions, light that passes through the cornea and then the lens will come to a perfect focus on the retina. But vision rarely remains perfect throughout a lifetime. In some eyes, light comes to a focus in front of the retina. In other eyes, the light isn't focused strongly enough. The retina may be perfectly healthy — it's the light reaching it that's the problem. In LASIK surgery, a specially trained eye surgeon (an ophthalmologist) uses an extremely precise laser to reshape the cornea of the eye in order to bring the light into focus for most tasks.

To correct nearsightedness (myopia), the surgeon uses the laser to flatten the central corneal surface, enabling light to focus on the retina.

To correct farsightedness (hyperopia), the surgeon uses the laser to flatten the peripheral or outer edge of the cornea, causing the central portion to steepen and increase its power

To correct astigmatism, the surgeon uses the laser to selectively reshape some portions of the cornea, flattening the steeper areas in an elliptical pattern

 

The three steps of LASIK

1. The corneal flap is created and lifted.Flap is created
2. An excimer laser reshapes the cornea.Excimer laser reshapes the cornea
3. The flap is replaced.Flap is replaced

With the addition of the Bausch & Lomb Zyoptix® and Alcon CustomCornea®  wavefront-guided systems, which maps thousands of data points  we obtain a fully detailed, three-dimensional picture of your cornea’s shape and characteristics. He is able provide a unique eye treatment for each eye, resulting in personalized vision correction that is as individual as your eye.   The advanced Custom Wavefront procedure does not have any additional costs at Joffe Medi·Center -- custom is our standard.
