A Concise Elucidation Of A Substitute To LASIK, Advanced Surface Laser Ablation
January 6th, 2010While LASIK (LAser in SItu Keratomileusis) surgical treatment can be regarded as one of the most well-liked kind of refractive surgery, there are situations when it cannot be done. For these condtions, an alternative type of laser vision correction treatment is considered. The ASLA (Advanced Surface Laser Ablation) technique is used when the LASIK method is belived to be unsuitable for a specific patient, for example, if the cornea is extremely slim or if the corneal topography is unbalance or if the corneal exterior coat (the epithelium) is uneven. ASLA can be used for correction of myopia or astigmatism, but it is not used for correcting hypermetropia. An eye expert will be able to conclude which system is the most suitable for a specific eye situation.
Here’s a detailed explanation of how the process is done. The ASLA procedure lasts about 15 minutes per eye. To start with, the cornea is anaesthetized. After that, anaesthetic drops are put on to the eye, and an eyelid holder is put in place to hold the eye from blinking. Also, anti-inflammation eye-drops are put on to the cornea in order to reduce the post-surgical effect and soreness. The corneal epithelium coat is removed after. The front surface deposit of the cornea (epithelium) is then softly lifted away from the rest of the cornea. This exposes the corneal ‘bed’ which is now all set to obtain the energy from the laser beam. The cornea is promptly re-shaped by the laser. The laser ray, consisting of UV power, vaporizes a pre-arranged total of tissue from the corneal bed, therefore giving the cornea the new shape required to correct the eye’s oscular treatment. Then, the baggy epithelium tissue can be placed back over the corneal bed. A soft contact lens is attached after. After this, the eye is fitted with a “band-aid” soft contact lens for added shield while the outside of the eye mends. Antibiotic eye-drops are also applied. Anti-swelling eye-drops are recommended.
About 4 days subsequent to surgical treatment, the contact lens is detached, and a string of gentle anti-soreness eye-drops is started. The ASLA system is parallel to the PRK (PhotoRefractive Keratectomy) and LASEK (LASer Epithelial Keratomileusis) method, but with certain improvements to support the recuperation of the eye. It is probable to have both eyes treated on the same date. For post-operation visual recuperation, it can take 4 days or more for patients to accomplish effective ability to see. The eyes usually feel coarse and painful for almost 2 days after surgery and, in other cases, they may even sense pain at first after the surgical treatment. Stabilization takes nearly 1-2 months. A gentle haze may be there for a several weeks.
