While LASIK (LAser in SItu Keratomileusis) operation can be regarded as one of the most popular way of refractive surgical procedure, there are occurrences when it cannot be done. For these situations, a different type of laser vision correction treatment is considered. The ASLA (Advanced Surface Laser Ablation) practice is used when the LASIK procedure is belived to be inapt for an actual patient, for instance, if the cornea is overly delicate or if the corneal topography is unbalance or if the corneal surface layer (the epithelium) is unstable. ASLA can be used for correction of myopia or astigmatism, but it is not used for correcting hypermetropia. An eye consultant will be able to ascertain which procedure is best appropriate for a particular eye situation.
Here’s a detailed description of how the method is done. The ASLA procedure takes about 15 minutes per eye. To start with, the cornea is anaesthetized. Second, anaesthetic drops are put on to the eye, and an eyelid holder is put in place to limit the eye from blinking. Moreover, anti-inflammation eye-drops are applied to the cornea in order to decrease the post-surgical outcome and pain. The corneal epithelium deposit is removed after. The front surface layer of the cornea (epithelium) is then gently lifted away from the rest of the cornea. This bares the corneal 'bed' which is now prepared to be given the energy from the laser beam. The cornea is promptly restructure by the laser. The laser ray, consisting of UV force, vaporizes a pre-arranged amount of tissue from the corneal bed, thus giving the cornea the new shape necessary to fix the eye's optical remedy. Then, the baggy epithelium tissue can be positioned back over the corneal bed. A soft contact lens is applied afterwards. Next, the eye is fitted with a "band-aid" soft contact lens for added armor while the outside of the eye restores to health. Anti-inflammation eye-drops are recommended.
About 4 days subsequent to operation, the contact lens is detached, and a string of gentle anti-irritation eye-drops is commenced. The ASLA system is similar to the PRK (PhotoRefractive Keratectomy) and LASEK (LASer Epithelial Keratomileusis) techniques, but with certain modifications to help the upturn of the eye. It is possible to have both eyes operated on the same day. For post-operation visual improvement, it can take 4 days or more for patients to accomplish helpful sight. The eyes frequently feel coarse and sore for about 2 days after surgical procedure and, in some cases, they may also feel tenderness initially after the surgical procedure. Recuperation takes all about 1-2 months. A gentle miasma may be present for quite a few weeks.
