LASIK eye surgery, also called laser-assisted in situ kerkatolmileusis, is a procedure that corrects vision problems and eliminates the need for glasses or contact lenses. This is a type of eye surgery that involves changing the shape of the cornea using a laser. With LASIK eye surgery, the main goal is to “bend light rays to focus more precisely on the patient’s retina” and produce clearer, sharper vision. In order to undergo LASIK eye surgery, the patient must first visit an ophthalmologist for a pre-surgical eye exam. However, the patient must meet the following criteria: be at least 18 years old, in good health, not have eye infections or injuries, not breastfeeding or pregnant, not suffering from dry eyes and not not wear a mask. contact lenses for a certain period. During the pre-surgical eye exam, the doctor will determine which areas of the cornea need to be reshaped using highly specialized instruments. The doctor will also take note of any irregularities in the eye before the operation. The operation does not take too long; it usually takes around 30 minutes. During the operation, the patient will lie on his back in a reclining chair and relaxed with the help of medication. Then the doctor will put numbing drops in the eyes. Next, the doctor will use a special instrument called an eyelid speculum, which will hold the eye open, and a suction ring will be placed over the eye before cutting the corneal flap. This may cause slight pressure and result in a slight decrease in the patient's vision. The surgeon may use a mechanical microkeratome, a special blade, or a laser keratome, a cutting laser, to cut a flap from the cornea. In the case of a doctor using a mechanical microkeratome, a ring will be placed over your eye to create ...... middle of paper ...... highlights, shadows, and see halos around lights. Anisometripia is the difference in refractive power between the eyes and aniseiknoia is the difference in image size between the two eyes. Although all this is very rare and unusual. Fifth, dry eye symptoms may worsen. After surgery, people may experience dry eye symptoms and develop even more severe dry eye symptoms. This includes burning, redness, and decreased vision after surgery. Usually, this condition is permanent and may require medications to improve tear production or spot blockages, which can close off the tear drainage system. Finally, you may lose vision completely. It is very rare for LASIK to cause vision deterioration that cannot be corrected by glasses or contact lenses. The result could be due to flap complications, equipment malfunction, infection, or extreme changes in the shape of the cornea..
