For correcting refractive vision problems, Lasik eye surgery is the common procedure done. Vision problems such as farsighted, near-sighted or astigmatism, Lasik eye surgery is opted by the people. The procedure can help improve your vision and reduce depending on the daily use of glasses or contacts.
What is Lasik eye surgery?
LASIK (Laser in Situ Keratomileusis) is the means of using a laser underneath a situ(corneal flap) to reshape the keratomileusis(cornea). A highly specialized laser called excimer laser is used to treat and correct the refractive error to improve the vision and eliminate a cent percent usage of glasses and contacts.
Why Lasik eye surgery is done?
Individuals may suffer from the main three vision problems- nearsightedness, farsightedness or astigmatism. A correction is required to improve the vision problems.
Nearsightedness (myopia): When the cornea curves sharply or the eyeball is longer than the normal state, the light rays concentrate and focus in front of the retina making it blur and affecting the distant vision. In this, a person can clearly see the objects that are near clearly but not those which are far away.
Farsightedness (hyperopia): When your cornea is too flat or is shorter than the average eyeball, the light that is to be focussed on the retina, focuses behind the retina. This makes it near vision and inturns make the distant vision to be blurry.
Astigmatism: The focus of near and distant vision is disrupted when the cornea flattens or curves unevenly.
How Lasik eye surgery is done?
A specially trained eye surgeon creates a thin and precise hinged corneal flap using a microkeratome. To expose the underlying corneal tissue the flap is pulled back. Later on, the cornea is reshaped by excimer laser ablates which can vary from patient to patient. The final step includes repositioning the flap back to the original position of the cornea without any stitches or bandages.
Requirements for Lasik eye surgery:
18 years or older
No change in the eye prescription in the previous year.
Your overall eye health must be good.
You should not be a pregnant or nursing woman.
Benefits of having Lasik eye surgery
Improved vision: Poor eyesight problems such as farsightedness, shortsightedness and astigmatism can be improved with Lasik eye surgery. A 20/20 vision or better is achieved.
Safe procedure: Compared to the previous and older times, Lasik eye surgery is now much safer with the availability of advanced technology and equipment.
Fast results and quick healing: The average healing time after the surgery are 24-36 hours. It can vary according to the individual and also if any complications arise from the placement of the flap.
Reduce usage of glasses and contacts: With undergoing such a procedure, you can reduce and eliminate the complete usage of glasses and contact lenses forever.
Permanent and long-lasting: Lasik surgery is performed for improving vision. After the procedure, a stabilization period of 3 months is present. After the prolonged 3 months stabilization period the aftereffect of the surgery is permanent and you can have improved eyesight that should last a lifetime.
