Customized LASIK Procedure Using Wavefront Mapping
Poor vision is caused by a series of structural defects to the eyes which result in some rays of light that do not focus on the retina precisely. These structural defects of the eyes are known as aberrations. Basic aberrations of the eyes cause myopia, hyperopia and astigmatism and are called lower order aberrations. These low order aberrations can be corrected using contact lenses, reading glasses or by a LASIK procedure. A phoropter is usually used to detect aberrations in the eyes as part of a thorough eye examination.
Dr. William Boothe is an expert in performing Wavefront guided LASIK. According to him, Wavefront technology can detect minute aberrations of the eyes which cannot be detected by a phoropter. These minute aberrations are known as higher-order aberrations. Wavefront technology or aberrometry measures the cornea by passing light through the lens and the cornea. Distortions which occur while the light passes are known as aberrations which indicate vision errors.
High order aberrations should be also be measured and treated as they are considered as the reason for many side-effects that occur after the LASIK procedure such as ghost images, halos, night vision problems and other such visual side-effects. Wavefront guided LASIK surgery reduces some of the higher-order aberration which in turn improves the post-surgery vision of the patient, especially night vision. Dr. Boothe is performing the wavefront guided LASIK procedure using an aberrometer. Patients are asked to place their chin on the chin rest. Then the patient has to peer through the device so that the light can be focused on the eyes. After a few seconds, the measurement will be completed and Dr. Boothe will get the printouts of the map.
Aberrometer measures the aberrations of the eyes in a three-step process. First of all, wavefront light will pass through the pupil to measure the diameter of the pupil. Then the light will be passed through the eyes to capture any distortions present. A wavefront map is made by comparing the measurements taken by the wavefront with the pre-programmed reference wavefront. The wavefront map of each patient differs just like the fingerprints of each individual.
The wavefront mapping consists of complete and accurate description of the aberrations of your eyes. Dr. William Boothe will use this wavefront map as the blueprint for the customized correction of your eyes. You cannot obtain a perfect wavefront map as no eye is perfect. Wavefront mapping is a painless procedure and you can do it within minutes. You do not have to use any kind of eye drops for wavefront mapping. Dr. Boothe is an expert in LASIK eye procedure and he uses wavefront mapping to get clear map of the eye in order to treat even the higher-order aberrations.
