Custom Wavefront Guided Laser Eye Surgery is a specialized Laser Eye Surgery technique that Dr. Modi uses to provide patients with more complex eyeglass and contact lens prescriptions the possibility of achieving a more precise visual outcome.
Many people do not realize that their eyes are really a living optical system made up of a number of optical components that together, produce the optical characteristics of your vision. The two main optical components of your eye are the cornea and the crystalline lens. As with any optical component, the cornea and crystalline lens may have distortions. These distortions are called aberrations.
About Optical Aberrations
Anyone who wears eyeglasses or contact lenses is familiar with the most common aberrations, which are called myopia, hyperopia and astigmatism. These aberrations are relatively simple aberrations and are thus are called ‘low order’ aberrations. Since they are relatively simple, low order aberrations can usually be corrected with eyeglasses and contact lenses. However, there are some optical aberrations that cannot be fully corrected with eyeglass or contact lens prescriptions because they are too complex. These aberrations are probably unfamiliar to most patients but include spherical aberration, coma and trefoil. Since these aberrations are much more complex, they are called “high order” aberrations. High order aberrations are not corrected with eyeglasses or contact lenses. During your Consultation, we will use the LADARWave Custom Cornea Wavefront System, a type of aberrometer, to fully measure the complexity of the prescription he is trying to correct. If Dr. Modi finds that you have considerable high order aberrations that make your vision uncomfortable, or that you might otherwise benefit, he will perform your Bladeless All Laser LASIK as a Custom Wavefront Laser Eye Surgery procedure to achieve the best possible results.
