How Does LASIK Work?
The shape of your cornea — the curved, outermost layer of your eye — plays a critical role in how well you see. When formed correctly, the cornea bends or refracts light in just the right way that allows it to land properly on the retina at the back of your eye, where it is translated into a clear image.
Distortions in the shape of the cornea lead to common vision problems such as nearsightedness, farsightedness, and astigmatism — or, more generally, what is called a “refractive error”. LASIK reshapes the cornea to eliminate the distortions, correct your refractive error, and give you better vision.
LASIK surgery at the Stephenson Refractive Surgery Center at the Dean McGee Eye Institute has three steps:
Step 1: We create your personalized vision profile using iDESIGN technology. This high-definition sensor uses more than 1,200 data points to render a 3D map of your cornea. Your surgeon then uses this information to create a custom LASIK treatment plan for you — all at no additional charge.
Step 2: We make your personalized LASIK flap using our state-of-the-art, ultrafast femtosecond laser. This laser uses tiny, precise pulses of light to create your unique flap — a thin layer of tissue that is folded back to reveal the corneal tissue underneath.
Step 3: Guided by the iDESIGN technology, we deliver your personalized vision correction using a second type of laser, an excimer laser, to gently reshape the cornea and smooth out any distortions to eliminate your refractive error. When finished, your surgeon will reposition the LASIK flap and your procedure is complete all in a matter of minutes.
20/20 or Better!
Through the skill of our surgeons, the use of the iDESIGN technology, and an all-laser approach to LASIK, most people experience vision that is 20/20 or better! Are you ready to see that clearly? Don’t wait. Schedule your free screening today by calling 405.271.2500.
