Custom LASIK - Custom Cornea Procedure

Custom Cornea Bet you didn't know you could get customized laser eye surgery… now you can! The world is your oyster when it comes to refractive surgery today. Modern technology has afforded surgeons many new abilities including the ability to deliver CustomCornea®. This new procedure is a derivative of traditional LASIK adopting a similar approach. The main difference between Custom Cornea and other LASIK procedures is:
  • The custom cornea procedure helps create a custom reshaping that meets your individual needs.

  • Custom Cornea® can help treat higher-order aberrations or other problems your doctor may not have recognized using a traditional exam. Treating these formerly undetected problems can result in improved vision, reduced glare and improved night vision.

How Custom Cornea Works
Custom cornea works by first capturing a picture of the eye including a combination of high and lower order aberrations. This is achieved using custom wavefront technology. A map is subsequently generated for each eye measuring the way the eye captures light waves pass through the visual cortex.

Next, the map is transferred direct to the laser system. This helps provide a guide for the laser. The system helps the computer match you eye to the laser so the treatment offered is more precise, or custom tailored to your individual eye.

Using this system, a competent surgeon can carefully reshape the cornea in a unique way not possible before. The wavefront map created for each eye acts as a cheat sheet or guide if you will, for the laser. The doctor is better able to exactly match the eye's position so treatment is less haphazard and more precise.

The Technology
How is this possible? Custom cornea LASIK involves technology formerly used by astronomers to make distant objects appear clearer. Whereas in times of old objects viewed by astronomers appeared blurry or distorted due to atmospheric elements, today astronomer have new custom technology available that help improve clarity.

In the same way, the new custom imaging technique used in custom cornea surgeries allows doctors to correct eye aberrations more precisely by mapping out higher and lower order visual disturbances exactly prior to surgery. This allows a sort of high definition view of the eyeball and cornea before surgery. Your doctor is better able to target and reshape your cornea using this map.

Many refer to the equipment used to map the eye as an "aberrometer" as its primary intent is mapping aberrations within the eye. Wavefront mapping is critical to the success of custom cornea surgery. Many times a surgeon will use wavefront mapping to decide the best type of laser treatment for a patient.

Surgeons using custom cornea procedures also use LADARVision to actively track the eye. This helps the surgeon reshape the cornea properly by allowing instantaneous scanning so a doctor can precisely shape eye tissue correcting for aberrations as the treatment is being delivered. An eye tracker keeps track of progress throughout the procedure.

LADARWave procedures are ideal for patients with roughly 8 diopters of nearsightedness. It is also useful for patients with roughly 4 diopters of astigmatism. Your doctor can evaluate whether you are a good candidate for this new, custom type of surgery.

If you are recommended for custom surgery, chances are you will enjoy a more satisfactory outcome from surgery than traditional LASIK patients. Again, because custom technology allows independent mapping of the eye before surgery, it allows for a more exact result. This reduces the risk of complications and side effects after surgery, and enhances your odds of achieving 20/20 vision.
