LASIK EYE SURGERY – ACHIEVING CLEAR VISION
LASIK (laser-assisted in-situ keratomileusis) is an eye surgery that is most commonly performed to reshape the cornea to help focus the light rays onto the retina for a much clearer vision. When the eye and the shape of the cornea are not perfect, the image of the retina becomes blurred, distorted or is out-of-focus. These defects in the focusing power of the eye are referred to as refractive errors. LASIK eye surgery is performed on people with the three types of refractive errors which are; myopia, hyperopia, and astigmatism. Therefore, this means a good vision and no more corrective lenses.

The procedure is usually performed when the patient is awake, but the eye surgeon will need to numb your eye with a few drops of topical anaesthetic. First, a mechanical surgical tool known as femtosecond or microkeratome will be used to create a thin flap in the cornea. Second, LASIK uses the excimer laser to access the corneal tissue and to remove a thin layer from it. The excimer laser directs its ultraviolet light beam to the underlying cornea and helps to eliminate microscopic amounts of tissues. It enables the cornea to get a new shape which allows light to focus correctly on the retina. The corneal flap should be put back in place after that and allowed to heal naturally. The surgery takes 10 to 15 munites on a single eye, but it is possible that the operation can be performed on both eyes during the same session.
Before the Procedure:
You will get an eye exam done before LASIK eye surgery, to ensure your eyes are healthy. The thickness of the cornea is also be examined to ensure you maintain enough corneal tissue after the surgery. The other tests that are done are; measuring the size of the pupils in both light and dark, measuring the curvature of the cornea and the eyes’ refractive error.
During the examination, you are required to tell the eye doctor about your present and past medical eye conditions or any eye surgery or trauma you have undergone. Open up about all the medications and medicines that you are currently taking including the unprescribed drugs since they can affect your operation or vision. It is also important to mention any medication allergies that you have.
● After the surgery, an eye shield might be placed onto the eye to protect the flap and avoid pressure or rubbing on the eye it heals. It is usually overnight.
● You may experience itching or burning, but in most cases, this feeling fades away within six hours.
● You MUST not rub the eye after the surgery to avoid moving or dislodging the flap. You can choose to close your eyes in the next six hours to have your eyes closed as much as possible.
● Patients tend to have hazy or blurry visions, but this will continue to fade away by the following day.
The eye doctor could prescribe a sedative or mild pain medication.
LASIK eye surgery works since 96% of patients get their desired vision. If enhanced, the percentage can increase.
● Results are experienced almost immediately or a day after the surgery.
● The eye is allowed to heal naturally hence no stitches or bandages are needed after the LASIK.
● There’s little pain associated with the operation due to the numbing drops used before the surgery.
● After LASIK, most patients report less dependence on the contact lens or eyeglasses, while others no longer need them.
● Years after the surgery, adjustments can be made to correct your vision further, since vision might change as you age.
Though the procedure has an excellent safety profile, risks may occur including night glare, corneal infection, dry eyes, light sensitivity, or night driving problems. Do not undergo this surgery if you are a breastfeeding or pregnant woman since the condition may affect eye measurements. If you take prescriptions such as Imitrex, Accutane, Oral Prednisone or Cardarone, you are also advised not to have the surgery. Consider discussing everything about LASIK eye surgery with your eye surgeon before making the decision have a good vision.
