The Lasik Procedure
The immense power of our eyes in conveying the details of objects we see to the brain is amazing. Our main objective has to lead a healthy life, giving special attention to our eye sight because almost all our activities hinge on a good eye sight. Problems in eyes or dysfunctional eyes are major impediments in life. One of the common problems of eyes is refractive error. The problem of refractive error can be surmounted by using glasses or contact lenses or by undergoing lasik surgery.
The surgeon uses a laser for reshaping the cornea of the eye in lasik surgery procedure. Apart from correcting refractive errors, lasik surgery can be used for improving the vision or for leading a life free of glasses and contact lenses. In this procedure, the laser used is a special one. It was one Loannis Pallikaris of Greece who ventured a full-fledged lasik surgery during’91. Much water has flown down the river after this and the procedure has undergone many appropriate modifications.
In lasik surgery, a hinged corneal flap is created by the surgeon using microkeratome. Then the flap is pulled back so as to reshape the cornea with a special laser known as excimer laser. Every patient has a pre-specified pattern. The surgeon then keeps the flap in its original position and no sutures are needed for this.
In the field of ophthalmology, many types of lasers are used. But all the lasik surgery procedures use only a particular type of laser known as excimer laser. All the manufacturers of laser for lasik surgery make this excimer laser only. Many types of laser ablations including conventional lasik surgery are conducted.
In conventional lasik, the surgeon depends on the patient’s glass prescription and hence each patient has a different parameter. Conventional laser comes with the risk of aberrations like glare, halos and night vision, though such cases are rare.
Some unavoidable complications may occur in Lasik eye surgery. You should also consider your occupation before you opt for lasik eye surgery. Your employers must be kept informed and only on obtaining their clearance, you should undergo this surgery. Further, you should have had a stable vision all through. If you suffer from advanced autoimmune diseases like lupus or rheumatoid arthritis, you should not opt for lasik surgery. If you have a decreased corneal strength resulting in a disease called keratoconus, then also, you can not risk opting for lasik surgery.
