Eyes, though small, are a complex but very important organs of our body. Eyes act as one of the main bridges between external objects and the brain. We rely mostly on our eyes for judging objects. If we ignore our eyes, it will be a terrible price to pay. Out of the many afflictions that may affect the eyes, refractive errors are quite common. We can get this problem corrected by wearing glasses, contact lenses or through a Lasik surgery.
In Lasik surgery, a laser is used underneath a corneal flap for reshaping the cornea. For correcting refractive errors, enhancing vision and for getting rid of glasses and contact lenses, you can go in for a lasik surgery in which a special laser is used. It was in’91 that one Loannis Pallikaris of Greece developed this procedure and from then on, more and more innovations are happening on this front.
During the Lasik eye surgery, the surgeon creates a hinged corneal flap with microkeratome, pulls back the flap and reshapes the cornea with excimer laser. Each patient will have a pre-specified pattern. The surgeon repositions the flap onto the cornea and sutures are usually not needed for this.
Though different varieties of lasers are used in ophthalmology, the one that is used in lasik surgery is a specific one called excimer laser. Many manufacturers make this special laser. There are many types of lasik surgery including conventional type.
Conventional lasik procedure mainly depends on the patient’s past history and glass prescription and hence the parameters for every patient are unique. Occurrence of rare complications such as glare, halos and night vision are not ruled out in conventional lasik surgery.
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.
