Los Angeles Lasik
Custom LASIK & Wavefront Optimized Custom LASIK There are several ways a Laser Eye Surgeon can treat higher-order aberrations. One way is through Custom Wavefront Guided LASIK; another useful way is through Wavefront Optimized Laser Eye Surgery. One of the most common aberrations or abnormalities that are present in the eye is spherical aberration. And it is also present in other common optical devices like microscopes, telescopes, and cameras. Consequently, the some manufacturers of these optical devices add in a particular modification for the spherical aberrations in their devices so as to deal with these aberrations. Patients who have spherical aberrations will find Wavefront Optimized LASIK very useful. But for the majority of patients with more complex and individualized prescriptions, Custom Wavefront Guided LASIK is the best choice for them in that it produces first-rate results suited to their needs. Photorefractive Keratectomy (PRK) Photorefractive Keratectomy or more commonly known as PRK has endured the test of time in proving that is a safe and in fact very helpful process for Laser Vision Correction. The only common factor between PRK and LASIK is the use of laser directed in the eye of the patient. But the procedure in PRK is altogether different from that in LASIK. Primarily, the difference is that the surgeon does not create a flap using a microkeratome. In PRK, the surgeon uses the laser in reshaping the outermost surface of the cornea to provide optical correction, not the tissue beneath a created flap as in LASIK. Also in PRK, a thin layer of the corneal epithelium is removed, resulting to temporary discomfort to patients. This can last for a few days depending on the degree of discomfort relative to each patient. Generally, a patient who undergoes PRK will take more time to recover visually than a patient who undergoes LASIK. A few days after undergoing PRK, a surgeon usually prescribes supplementary medications to aid in better recovery, and a soft bandage contact lens to make the patient more comfortable. Although PRK is only seldom recommended, it suits the needs of some patients who are active or reserved military personnel, whose corneas show signs of scarring resulting from some kind of trauma or infection, or those whose corneas are too sensitive for LASIK anyway.
