So you can look forward to get a better vision of the beautiful world around you

;

It is one of the most effective methods to improve the vision of a person who has a poor visionary power by reshaping the cornea using a laser and thus has become a very common surgery as needed by an individual. LASIK stands for Laser-Assisted In Situ Keratomileusis and is a procedure that permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser. A knife, called a microkeratome, is used to cut a flap in the cornea

Reasons for doing the LASIK Eye Surgery

The reasons why a person may consider LASIK Eye Surgery :

;

;
• They can't wear contact lenses and would prefer not to wear glasses for cosmetic reasons.
;
;
• They want to engage in work or leisure activities that cannot be done while wearing glasses or contact lenses.

Some medical issues that can kept in the mind before the Lasik eye surgery

;

People thinking about laser eye surgery should consider these issues:

;

;
• You should be at least 20 years old before you consider laser eye surgery.
;
;
• The refractive error (prescription in glasses) should be stable.
;
;
• People with diabetes, uncontrolled rheumatic conditions, diseases of the immune system or a family history of keratoconus should be very careful in proceeding with laser eye surgery. An experienced refractive surgeon will be able to advise you appropriately.

Operation procedure of the Lasik eye surgery

;

The excimer laser is a 'cool' type of laser. It doesn't burn tissue, but vaporises small amounts of the cornea every time a beam of the laser is pulsed onto the surface of the eye. The diameter of the laser beam and the number of pulses that are directed onto the cornea are carefully controlled using computer technology, so that the surface of the cornea is reshaped.

The procedure is performed using local anaesthetic eye drops and takes between five and 10 minutes per eye. However, the time taken for the reshaping of the cornea with the excimer laser is usually less than a minute.

If the procedure is successful, the cornea is able to focus light rays directly onto the retina at the back of the eye, rather than in front of or behind the retina.

Some possible side effects of the Lasik eye surgery

There can be some of the expected side effects after the operation is over which are given as below:

;

;
• Treatment not successful - this may be due to over treatment or under treatment. You may need a second 'enhancement' procedure.
;
;
• Dry eyes - you may need to use lubricating eye drops.
;
;
• Delayed healing - the superficial layer of the cornea or the flap (if LASIK procedure was used) may not heal properly. Follow-up treatment may be required.
;
;
• Infection - treatment with antibiotics may be necessary.
;
;
• Superficial scarring - this will require a further procedure to fix.
;
;
• Excessive thinning of the cornea - this may lead to a return of sight problems and require the use of contact lenses or further surgery.
