Even though LASIK (LAser in SItu Keratomileusis) operation can be regarded as one of the most accepted form of refractive surgical procedure, there are cases when it cannot be carried out. For these circumstances, a different from of laser vision correction treatment is considered. The ASLA (Advanced Surface Laser Ablation) practice is used when the LASIK system is considered incompatible for an actual patient, for example, if the cornea is very delicate or if the corneal topography is irregular or if the corneal outside coat (the epithelium) is uneven. ASLA can be used for repairing of myopia or astigmatism, but it is not used for repairing hypermetropia. An eye specialist will be able to establish which procedure is the most appropriate for a particular eye condition.
 
Here’s a detailed account of how the procedure is done. The ASLA process takes about 15 minutes per eye. To begin with, the cornea is anaesthetized. Next, anaesthetic drops are applied to the eye, and an eyelid holder is put in place to keep the eye from blinking. Also, anti-inflammation eye-drops are put on to the cornea in order to diminish the post-surgical outcome and distress. The corneal epithelium layer is detached afterwards. The front surface deposit of the cornea (epithelium) is then gently lifted away from the rest of the cornea. This exposes the corneal ‘bed’ which is now all set to receive the energy from the laser beam. The cornea is immediately restructure by the laser. The laser ray, consisting of UV energy, vaporizes a pre-determined amount of tissue from the corneal bed, therefore giving the cornea the new shape required to fix the eye’s optical remedy. Then, the loose epithelium tissue can be placed back over the corneal bed. A soft contact lens is put on afterwards. After this, the eye is fitted with a “band-aid” soft contact lens for added shield while the outside of the eye restores to health. Antibiotic eye-drops are also put on. Anti-inflammation eye-drops are recommended.
 
About 4 days after surgical procedure, the contact lens is disengage, and a course of mild anti-soreness eye-drops is commenced. The ASLA method is comparable to the PRK (PhotoRefractive Keratectomy) and LASEK (LASer Epithelial Keratomileusis) method, but with particular improvements to help the healing of the eye. It is possible to have both eyes treated on the same date. For after surgery visual recuperation, it can take 4 days or more for patients to achieve constructive eyesight. The eyes typically feel gritty and painful for around 2 days after surgical treatment and, in other cases, they may even sense tenderness at first subsequent to the surgery. Recuperation takes all about 1-2 months. A soft haze may be there for quite a few weeks.

LASIK is a form of surgery executed fundamentally on the corneal (the transparent superficial stratum of the eyeball) part of the eye. Long before LASIK (Laser-Assisted in Situ Keratomileusis) surgery was accepted, many types of eye surgery are being determined and experimented by surgeons to remedy certain eye defects and problems. The technique of LASIK was discovered way back in the 1950’s by a Columbia-based Spanish Ophthalmologist. The continuous studies, research and experiment regarding this procedure has brought transformation and a huge step in advance for the progress of knowledge and discovery of other methods like RK (radial keratotomy), wavefront-guided PRK and the latest intraocular lenses. This technology is also now applied in Astigmatism Surgery.

Here’s an overview of Laser Surgery for better perception: LASIK (Corneal surgery), is an irreparable eye operation that is basically carried out to correct Myopia (near sightedness), Hyperopia (far sightedness) and Astigmatism (abnormal curvature of the eye lens). It is executed by an Ophthalmologist after several tests in able to ascertain if the client is a candidate for the surgery. For many patients, LASIK is a good alternative to avoid the use of contact lenses and/or eyeglasses since all of them are for the purpose of correcting eye problem.
 
The full procedure will only take 10 to 15 minutes each eye and only needed a mild sedative and anesthesia and is categorize as an out-patient surgery. But just like any other procedure, an informed consent is needed since, although LASIK is an OPD type operation, it is still a harsh procedure and may cause complications to the patient. Diagnostic assessments are necessary. Primary reason for it is of course you don’t want to have your cornea being flapped and suctioned for no reason at all and secondly, for your Ophthalmologist to know what accurately needs to be done, what are the possible complications that might happen and be prepared ahead of time.
 
Beforehand, several arrangements and familiarization are done. The operation proper is divided into 3 main procedures. First is the makingconstruction of a flap in the corneal tissue. The second is the laser remodeling. With the use of Excimer laser, the corneal stroma will be remodeled based on how much stroma will be remove based on the diagnosis. Thirdly and finally, the repositioning of the flap. In this step, the surgeon will put back the flap to its place but first the presence of debris and bubbles are checked before it is placed back. No suture are required. The “initial success” postoperative process will be laid to the patient’s sleep pattern (in order to permit the natural adhesion and curing process of the eye), some anti-infectives and anti-inflammatory eye medications.
 
Despite the minimal aberration the LASIK surgery cause, there are still safety measures that needs to be done by the patient to limit or even forestall further complication. Some of these are: regularly and lengthened sleep hours, use of eye shield or patch to prevent the accidental rubbing of the operated eye, avoid stooping and bending to avert the increase of eye pressure, apt and strict obedience with prescribed medication and of course follow-up check up.
