Refractive Surgery Technology
Intraocular lenses (IOLs) are used to replace the crystalline lens during cataract surgery. They are approximately one-third the size of a dime. They can correct nearsightedness, farsightedness, and astigmatism. Standard IOLs are monofocal, meaning they correct vision at just one distance. However, there are premium IOL options that can improve focus at a range of distances.
Wavefront LASIK Technology
Dr. Goel offers wavefront LASIK, a highly customized version of LASIK, for the benefit of his patients who wish to not only improve focus, but also correct higher-order aberrations such as halos, glare, and compromised night vision. Dr. Goel uses an aberrometer to measure how light rays travel through the eye. This method is 25 times more precise than the traditional method of using a series of lenses to determine the extent of correction necessary.
Wavefront LASIK involves a more precise analysis of the eye, making it possible to correct higher order aberrations.
Blade-free LASIK Technology
Blade-free LASIK, or iLASIK, uses lasers to create the corneal flap instead of a keratome blade. Pulses of laser light cause tiny bubbles to form under the corneal surface. These bubbles separate the tissue so that Dr. Goel can gently access the stroma, or center of the corea. This method is far more precise than using a blade, and minimizes the risk of infection.
Epi-LASIK may be an option for patients with thin corneas who are not candidates for traditional LASIK. Epi-LASIK involves creating an ultra-thin corneal flap. Next, as in traditional LASIK, the stroma is refined with the excimer laser. Finally, the flap is replaced, and healing is facilitated with the use of a special contact lens. After about three days, patients are usually cleared to remove the contact lens.
