LASIK (Laser in Situ Keratomileusis) is recommended to correct vision through reshaping the cornea. Usually, vision correction is suggested to people who suffer from nearsightedness, farsightedness or who have astigmatism.
LASIK is one among the many surgical techniques used to alter the shape of the cornea so that light traveling through the cornea will directly focus onto the retina.
The procedure uses a highly specialized laser to improve vision, correct refractive errors, as well as to get rid of glasses or contact lenses.
During the surgical procedure, a specific flap-making instrument to create a thin flap in the cornea. Using Excier Laser, a fixed amount (which are usually calculated based on the pre-operatively determined power of the patient’s eye) of corneal tissue is removed in order to reshape the cornea. After reshaping the cornea, the flap is replaced and within few hours, the surface layer of the cornea (epithelium) starts to develop over the edge of the flap to bond it into position. Within days, collagen bonds from within the cornea around the flap.
Though LASIK surgery is technically complex, it can be completed in about 10 minutes and is usually done while the patient is under local anesthesia (eye drops) and if required a mild sedation.
It takes less time frame for healing after the surgery; the vision may be blurred and obscure for the first day but improves within a few days post surgery.
Post-surgical medications include eye drops to prevent infection, inflammation as well as to keep eyes moist. After the surgery, the patients will have to revisit the doctor after 1-2 days for immediate follow-up. Apart from that, post-surgery, the patient may have to revisits the doctor at regular intervals within the first six months.
Certain health conditions can make the surgical process complicated and can cause additional risks as it may interfere with the healing process. These conditions include eye infections, eye inflammation, dry eyes, corneal diseases, corneal scarring, lupus, rheumatoid arthritis, and diabetes with advanced retinal disease among the others.
Further, pregnant women are highly suggested not to undergo LASIK eye surgery as the medication used to dilate the pupils is not recommended for administration to pregnant women.
It is highly recommended that you must take up a Lasik checkup package before proceeding to the surgery as it prevents any further health complication during the surgery. The package includes pre-initial work-up and consultation, procedure, and post-operative kit(contains eye drops and eye glasses). Manipal hospitals offers this Lasik checkup package at a cost efficient rate of Rs 27,200. You can opt for this simple procedure to lead a life free from the clutches of eyeglasses and contact lenses.
