Custom LASIK or “Wavefront-Driven LASIK” is a recent advancement in laser vision technology that allows the surgeon to personalize the procedure and to potentially improve the already excellent results obtained with traditional laser vision correction.
This procedure uses wavefront technology, which provides new diagnostic information previously unattainable.
Wavefront lasik eye surgery is a very popular form of vision correction operation done today by many experienced lasic surgeons. Originally approved by the Federal Drug and Food Administration in 2002, the procedure uses a very sophisticated computer system to map out the entire outer and inner eye of the patient. It is different from standard lasik operations because wavefront lasic eye surgery requires a highly skilled surgeon to complete the procedure successfully for real results.
History of LASIK
Wavefront technology was first developed in 1978 by Josef Bille, Ph.D., director of the Institute for Applied Physics at the University of Heidelberg , to measure wavefront distortions that occurred when light traveling through the atmosphere entered a telescopic lens. This technology removed any visual distortion or aberrations from the atmosphere allowing astrophysicists to more accurately view images of the stars and planets.
It is now possible to utilize this technology to record detailed information about the visual characteristics of the eye. Unlike standard measuring devices such as corneal topography, which measure the front surface of the eye called the cornea, the wavefront scans the way the entire optical system processes light.
A computer system reveals a three dimensional imaging of the whole eye, particularly the corneal flap and cornea region of the inner eye. The surgeon then receives a large amount of detailed information of the patient’s eye to help them gauge and guide the incision points. He or she will be able to locate the exact problems and refraction points of the eyes that needs fixing.
The lasers will then be targeted to those particular areas. The doctor uses this whole mapping process as an aid for accuracy. The doctor can also identify any additional problems with the eye. The whole operation is diagnostic in nature as well.The laser is then aimed directly onto the cornea and eye with this process. The lights from the lasers then passes through the eye for refraction.
This is all done after the surgeon takes essential data and computes it into a single formula that will be used to help the patient achieve better vision. The outcome is usually perfect vision. Patients undergoing this process will be able to get 20/20 vision. Their vision will be restored fully. In some cases, vision may be better than 20/20. This type of operation also reduces the chances of long term complications and risks like blurriness, dry eyes, red eyes, and halos. Side effects are common in some patients with regular lasic. Wavefront lasik eye surgery reduces the onset of certain side effects in most people.
The different types of Wavefront LASIK technologies available today
Here are the types of Wavefront LASIK technologies being used today:
- Allegretto Wave Laser – This is a product from Wavelight AG. It is being used by the top laser eye clinics in the United Kingdom today. This product is known to be one of the fastest laser types today. In order to determine the precision and the speed of the Allegreto, Perfect Pulse technology is being utilized in order to make sure that everything is as exact as possible. This kind of procedure is also safe because it makes sure that the laser beam’s energy level is just right before it even makes contact with the eye. In this kind of advanced technology, the position of the eye is tracked in real time. If the patient’s eye moves, the laser will stop immediately and resume only when the patient’s eye returns to its normal position. One of the similar tracking technologies to this Allegretto Wave laser is the ActiveTrak 3-D.
- Allegro Topolyzer – This instrument has the ability to track existing irregularities in your eye. It will measure and generate data in great detail. The resolution is very high. You will be able to identify keratoconus using this instrument. A Pentacam camera system is used in order to look at the back of the eye and in order to create a three dimensional model which will be later analyzed by the surgeon.
- Nidek OPD – This technology enables you to measure the progress of thousands of light waves as they pass through several parts of your eye.
