Refractive surgery is a procedure made to correct common vision problems such as farsightedness, nearsightedness, astigmatism, and presbyopia. It also helps reduce patients’ dependence on prescription eyeglasses and contact lenses.
One of the well-known refractive surgeries performed nowadays is LASIK eye surgery. Also known as Laser-assisted In Situ Keratomileusis, it is a commonly performed laser eye surgery to treat conditions like hyperopia (farsightedness), myopia (nearsightedness), and astigmatism. The procedure reshapes the cornea to allow the light that is entering the eye to be properly focused onto our retina. This way, patients will have clearer vision.
LASIK eye surgery is pain-free and can be completed in just 15 minutes. It only requires topical anesthetic drops, and has no stitches. Patients can expect the results to be apparent in as little as twenty-four hours. Most patients would be ready to return to work by the following day.
How Is LASIK Surgery Performed?
Your eye surgeon will start by using a microkeratome or a femtosecond laser to make a thin and circular flap in your cornea. This tool is a highly specialized laser that uses a cool ultraviolet light beam to remove tissues from your cornea. Your cornea is then reshaped by a second laser so that it can accurately focus light on the retina for better vision. As for nearsighted patients, the goal is to flatten their cornea, while for farsighted people, they will need a steeper cornea. The excimer lasers are also used order to correct astigmatism
Once the laser has already reshaped the cornea, the flap will be laid back in place to cover the area where corneal tissue has been removed to allow it to heal naturally.
What to expect prior to your LASIK surgery
A thorough eye examination will be performed by your doctor to ensure your eyes are in good condition for the procedure. From the shape and thickness of the cornea, refractive errors, pupil size, up to the any other eye conditions, a comprehensive examination will be carried out to ensure that you are ready for the LASIK treatment. Even the moistness of the eyes will have to be evaluated. You may even be advised to take precautionary measures in order to reduce any risks of developing dry eyes after the surgery.
In most cases, your eye surgeon will use an automated instrument known as the corneal topographer to measure the curvature of the front surface of the eye, and then create a map of your cornea. He or she will also take note of your general health history so be sure to inform him or her about it. You are also encouraged to inform your doctor about any medications that you might be taking. Not telling your doctor of these important things can greatly affect your surgery and its results. Moreover, you will be advised to stop wearing contact lenses 1-2 weeks prior to your eye exam and surgery, as contact lenses can alter the natural shape of your cornea.
After the LASIK surgery has been completed, your surgeon will ask you to rest for a bit. Should you experience burning or itching sensation following the procedure, do not panic as it is normal and temporary. Your surgeon will also do a brief post-operative check before you go home.
