lasik surgery
lasik is carried out whilst the patient reposes below a surgical machine called an excimer laser.
First of all, the eyeball is numbed with a some drops of topical anesthetic. An eyelid holder is positioned ‘tween the eyelids to hold them open and stop the person from blinking.
A suction ring positioned on the eye elevates and flattens the cornea and assists in preventing the eye from moving. The patient might experience pressure from the holder and suction ring, akin to a finger squeezed firmly on the eyelid.
From the time the suction ring is placed on the eye till it is taken away, sight may slowly dim or becomes black. When the cornea is flattened, a hinged flap of corneal tissue is made using an automatic microsurgical machine, either a laser known as a keratome, or an instrument named a microkeratome blade. The corneal flap is elevated and turned up. Then the excimer laser preprogrammed with the patient’s specific eye measurement is centered on the eye.
The consultant ensures the laser is placed accurately. The patient looks at a specialised light, named a fixation or target light, whilst the excimer laser sculpts the corneal tissue. Then the consultant directs the flap back into place and smooths out the edges. The corneal flap adheres to the primary cornea inside a few minutes, therefore stitches are not required.
The patient should be sure to have somebody drive them home following the operation and take a short sleep or just generally unwind. To assist in protecting the cornea as it mends, the surgeon might put a see-through shield across the eye(s) to protect against inadvertent blows and to prompt the person not to rub their eye or eyes. The patient might have to wear the shield only when sleeping. The consultant should supply eye drops to assist the eye to heal and alleviate dryness.
It could take up to six months following LASIK surgical procedure for the improvements in someones sight to amply steady and side effects to go away. However it has become a very popular procedure now throughout the world, with many people proclaiming how it has changed their lifes for the better.
If you are thinking of undergoing lasik eye surgery, then you must weigh up the pros and cons before deciding whether it will improve your lifestyle, or whether in fact you could maybe do without it.
