LASIK eye surgery has helped millions worldwide to see clearly without using spectacles or contact lenses. It is the most popular refractive surgical procedure since there is little or no pain and corrected vision occur the following day. LASIK is an acronym for laser assisted in- situ keratomileusis.

Five things you should know before deciding to go ahead with LASIK eye surgery are listed below.

1. Lasik. What is it It is a refractory surgical procedure for correcting short and long sightedness. During the procedure a thin flap is created either by a cutting instrument called microkeratome or by the newer IntraLase laser. The surgeon lifts the flap, then ablates the required corneal tissue with an excimer laser to reshape the cornea.The flap is then replaced over the area where the tissue was ablated. This flap acts as bandage over the treated cornea. The surgeon carrying out the procedure uses a computer to calculate and prepare the laser for the particular refractive problem of the patient.

2. What to do before LASIK eye surgery When seriously considering this surgical procedure,the most important thing to do is find a reputable and experienced eye surgeon. A good surgeon reduces the risks of complications. The eye specialist will examine you to determine your visual defect, and the amount of laser ablation needed. If you have dry eye disease, treatment will be necessary before the procedure. A map of the cornea will be produced by a corneal topographer, and you may have a wave front analysis that precisely maps out the area of visual refractive defect. Your surgeon will assess your general health and medication and decide whether you qualify on health grounds for LASIK eye surgery. If you are not offered a patient information booklet, you should ask for one. Before LASIK treatment you should know what to expect after the procedure. You are more likely to be satisfied if before treatment, you know the outcome and fully understand the potential risks and complications.

3. What happens during LASIK treatment This treatment is quick and you are awake throughout. The surgeon may give you a mild sedative tablet before the procedure. Even though you will walk out of the treatment centre, you should be accompanied, to make sure you return home safely. The surgeon may insert anaesthetic drops into your eye, and while you lie down, he or she will align the laser directly over your eye.
Your eye will remain open and pressurised by a retainer with a suction ring. The surgeon will mark out the area of the cornea. The flap is then created either by a microkeratome or IntraLase laser. The flap is then lifted. You will then be asked to focus on a light source while the excimer laser delivers pulses of high beam light on to the cornea.
You will hear a consistent clicking sound during treatment. You may note an acrid smell during treatment. The time taken depends on the extent of your optical refractory defect. The flap is then replaced. You will be told to rest for a while.

4. What are the complications In the past, following LASIK eye surgery, there were as much as 5% of people experiencing one or other significant problem. Today the adverse effects are much less and the commonest ones are haze, halos and glare. Problems often results from the hinged flap particularly if it does not adhere to surface properly, or it is cut too thin or thick. This can result in irregular astigmatism, keratoconus or diffuse lamellar keratosis (DLK). In astigmatism, can develop double vision or ghost images. In DLK, debri produce inflammation under the flap. Urgent treatment will reduce potential permanent visual loss. In keratoconus, the surface bulges. This can happen if the flap is too thick. Up to 50% complain of dry eyes after LASIK eye surgery. Most disappear after 6 months. Artificial tears will help. There may be under correction or over correction. Eye infection or irritation is uncommon but if present, will require treatment.

5. What to expect following LASIK eye surgeryAt the assessment stage, make sure youare fully aware of what you should expect following and after surgery. You should expect 20/20 vision or better but remember that 20/40 or better is good enough to drive without glasses or contact lenses. A study by US Military on 16,000 army personnel after LASIK eye surgery, between 2000 and 2003 showed that 86% had 20/20 or better vision and 98% achieved 20/40 vision or better. If the predicted outcome is not what you expect, then you have to make an informed decision based on the expected results, risks and cost.
