All About Lasik Surgery

Posted by admin Filed in Vision on Tuesday, August 4th 2009

Welcome back!

Lasik surgery is a medical procedure that is carried out by an ophthalmologist. It is used to correct abnormalities on the cornea of the eye such as myopia, astigmatism or hyperopia. These abnormalities usually end up impairing the vision, and are usually resolved by the wearing of corrective eyewear such as glasses or contact lenses.

The procedure is a form of refractive surgery that is frequently referred to as photorefractive keratectomy. The procedure involves the use of a laser and other specialist equipment. The procedure takes around thirty minutes to complete and a patient can expect to be fully healed within a short space of time while suffering absolutely minimal physical pain or discomfort.

After a series of consultations with the surgeon who will be performing the operation, the patient is asked to attend the clinic on the day of surgery itself. In the pre-operation stage the patient will be given a medicine to take that acts as a relaxant. This will be given time to work and the patient will be allowed to relax while the effects take place.
Once ready, the patient is sat in a chair that can recline to a horizontal position. An anaesthetic solution is the dropped into the eye using a pipette.

While the anaesthetic is given time to work, the surgeon will begin by mapping the eye. This is a computer generated process that is carried out by producing a blueprint for the eye that includes higher and lower order aberrations. This allows for the most accurate of surgical procedures and uses a format called Wavefront technology.

This is a more advanced method of the bladed procedure and is appropriately known as bladeless surgery.
The eye itself is kept open by a special instrument called a speculum while the other eye is kept protected with a separate shield. An instrument called a microkeratome will be used if the bladed form of surgery is being employed to cut a small hinged corneal flap on the outer layer of the eye.

In the bladeless form of surgery, a high temperature laser called an intralase will perform this part of the surgery instead.

After the flap has been created, another laser called an excimer is used to remove incredibly precise amounts of corneal tissue that is dictated by the mapping process mentioned earlier.
The amount taken will be enough to correct the abnormal shape and then the surgeon will apply very short bursts of light with the laser to actually reshape the cornea.

Once the cornea has been replaced, the hinged flap on the outer layer of the eye is replaced and the speculum is removed. The flap requires no stitches and will heal itself reasonably quickly.

Although the actual surgical procedure only lasts around 15 minutes, the pre-operative implications mean that the experience will last for around one hour in total.

Patient can go home the same day although they are not allowed to drive themselves, and a follow-up appointment takes place to check on the healing of the eye. Although vision can be blurred for some time afterwards, over 95% of patients are able to see perfectly afterwards.
