Today, more people are exploring alternative options to the old faithful tested glasses and even the more modern contact lenses. Laser eye surgery has fast become the procedure of choice for people seeking an unconventional and effective way of correcting vision. And whatever your specific problem or need, there is a technique available to address it.
Laser in situ keratomileusis (LASIK) - This is perhaps the most popular of all laser eye surgery techniques. With LASIK, a blade is used to cut a flap in the cornea to allow the surgeon to access the middle layer of the cornea. This is where the excimer laser is applied to reshape the cornea, and many feel the results are more effective than other treatments like LASEK and PRK. Once the process is completed, the eye is bandaged, and the patient is expected to have full recovery in one to two weeks. Patients who are myopic, hyperopic or even those who suffer from astigmatism can expect to have good results from a LASIK procedure.
Laser epithelial keratomileusis (LASEK) - LASEK is somewhat similar to both LASIK and PRK. An alcohol solution is applied to the cornea, after which a blade is used to cut a flap in the epithelial layer. Thereafter, an excimer laser is used to reshape the cornea based on the patient’s particular needs. This 15 minute procedure ends when the flap is replaced and allowed to settle into its original position. Patients experience discomfort for about 2 days after surgery, and complete healing usually takes about a week. This procedure is best suited for people with very thin and flat corneas.
Photo-refractive keratectomy (PRK) - PRK is the first surgical procedure to utilize lasers as part of the treatment. With this technique, there is no flap created. Instead, an excimer laser and epithelial scraper are used to completely ablate the cells from the cornea’s surface. relex smile takes a couple of minutes. Antibiotics are usually prescribed for about 5 days after the procedure is completed. Complete healing and recovery usually takes a few months, after which patients can expect to have significantly improved vision. This method is typically used for people who are myopic or hyperopic.
