Lasik is a laser surgery used to restructure the cornea of eye also known as Laser in Situ Keratomileusis.
In this surgery, a laser is used underneath the corneal in situ or flap to reshape the cornea.
Excimer laser, which is a highly specific laser, is used in this surgery.
This laser was specially designed for treating errors of refraction, improving vision, reduce the number of eye or completely eliminate the need of wearing glasses or even contact lenses.
Cornea, which is the front transparent covering of the eye, is restructured with the help of laser surgery.
Excimer laser was used for the surgery of eye even before the introduction of Lasik surgery but the credit of introducing the procedure of Lasik surgery and incorporating the Excimer laser for use in it goes to Loannis Pallikaris.
During the surgery, first a thin hinged, precise corneal flap is created by a specialized surgeon.
This is done using a microkiratome.
Now to bring the corneal tissue to exposure, the flap is pulled by the surgeon.
Now comes in the role of Excimer laser to ablate the cornea to a pre specified pattern which is kept unique for every patient.
Now gently and slowly the flap is relocated over the cornea with no sutures.
Advantages: • Immediate outcome: One of the most remarkable outcome which is truly experienced by almost every patient is the immediate result achieved by surgery.
While through other visual acuity, it may take up to six months to achieve desired result, a near perfect vision may be achieved using a Lasik surgery within no time.
The patients may discontinue use of glasses or contact lenses almost immediately after the surgery.
• Technical advancements: The latest technical advancements are incorporated in the Lasik surgery eliminating the risks associated with clinical surgery which bring about visual injuries after a refractive surgical procedure.
• Satisfaction rate: According to a survey approximately 95-98% people are satisfied with the results obtained after Lasik surgery.
• Level of correctness: Using Lasik surgery most of the cases of hyperemia, myopia and astigmatism may be corrected.
Also since the entire procedure is carried out using a computer, there is very less chance of errors.
• Lastly, only a single surgical procedure is required in most of the cases to achieve the desired results, but there is scope of enhancements if the patients desire.
This can also be done even many years later.
Disadvantages: • Irreversible nature: Since the surgery is performed on the most delicate organ of the body which is the eye, it is not possible to reverse back the outcome of surgery.
• Variations in result: As the recovering power of each patient varies, in one case the results may be observed within an hour of the operation while in some other case it may take up to a day.
• Extent of outcome achieved also varies from person to person while one person may achieve the desired result in a single surgery and the other person may require some enhancements to be performed after the surgery.
Also some people may feel the need of wearing glasses after their first surgery although it will be of a lesser number.
