LASIK Surgery Procedure and its Risks

LASIK surgery is often done to correct visual disturbances. However, just like any other surgery, this procedure also has risks. Therefore, it is important to know a few things about LASIK surgery before undergoing it

LASIK surgery or laser-assisted in-situ keratomileusis is a medical procedure aimed at treating several vision disorders, including nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.

This operation is performed using a laser beam to erode the corneal tissue of the eye, so that vision becomes better and the patient can be free from wearing glasses or contact lenses.

LASIK Surgery Alert

To avoid things that are not desirable, you should avoid the LASIK surgery method if you:

  • Has good eyesight
  • Frequently do physical activities or sports related to collisions to the face
  • Has large pupils or thin corneas
  • Has vision problems related to drug use or aging, such as presbyopia
  • Currently pregnant or breastfeeding
  • Suffering from autoimmune diseases, such as rheumatoid arthritis
  • Have a weakened immune system due to immunosuppressive treatment or suffer from HIV
  • Suffer from certain eye disorders, such as dry eyes, inflammation of the cornea, eyelid disorders, glaucoma, cataracts, and herpes simplex

Preparing for LASIK Surgery

Doctors will usually do the following before LASIK surgery:

  • Perform a thorough eye examination to make sure the eyes are in good condition for the procedure, such as measuring corneal thickness, pupil, refraction, and eye pressure
  • Ask about the general medical history of the patient and the medicines he is taking
  • Explains an outline of the procedure during LASIK surgery, handling after it, as well as the risks and benefits of this surgery

For patients, the following things need to be adhered to so that LASIK surgery runs smoothly:

  • Not wearing contact lenses for at least 3 weeks before eye examination and before surgery
  • Bring commonly used glasses
  • Do not wear eye makeup or hair accessories that can interfere with the position of the head during LASIK surgery
  • Clean the eyelashes every day before LASIK surgery to remove dirt and minimize the risk of infection

LASIK Surgery Procedure

Most LASIK surgeries are completed within 30 minutes. The procedure is as follows:

  • Patients will be asked to lie down on a special chair.
  • Patients may be given medication to relax during the procedure.
  • Patients will be given local anesthetic in the form of eye drops so they don't feel pain during surgery.
  • The doctor will use a device to hold the lid open after the anesthetic is administered.
  • The doctor will ask the patient to focus on looking at a single point of light during the operation process.
  • The doctor will put a suction ring on the eye.
  • The doctor will start making small incisions on the surface of the eyeball using a small scalpel or laser.
  • From this incision, a fold will be formed on the cornea. This surgery aims to change the shape of the cornea to be repaired as needed.
  • When finished, the cornea will be closed again and the fold will be attached by itself without the need for stitches.

After LASIK Surgery

Immediately after LASIK surgery, the patient's eyes may feel itchy, gritty, hot, and watery. To help relieve it, the doctor will give you eye drops. Patients can also resume their postoperative activities, but the doctor may suggest resting for at least 1 day.

The vision of post-LASIK patients has not returned to normal for up to 2-3 months. To speed up healing, the patient needs to do the following things:

  • Wear eye protection while sleeping
  • Do not rub the eyes harshly
  • Not swimming or using hot tubs for about 2 weeks after surgery
  • Do not do strenuous exercise for at least a week
  • Checking the eye condition regularly to the ophthalmologist to monitor the progress of vision after surgery
  • Take medication prescribed by the doctor regularly

The Risks of LASIK Surgery

Some of the side effects that patients may experience after LASIK surgery are:

  • Dry eyes
  • Disorders of the corneal folds, caused by infection or imperfect healing of the corneal tissue
  • Astigmatism, which can occur when tissue erosion is uneven
  • Sensitive to light
  • Visibility
  • Undercorrections, which can occur when the laser removes too little tissue from the eye
  • Overcorrections, which occurs when the laser removes too much tissue from the eye

The above risks are usually temporary and will disappear within a few weeks after surgery. However, in a few cases, the surgery is not successful, so the patient must continue to wear glasses or contact lenses, or may even need to undergo additional surgery.

Therefore, before deciding to undergo LASIK surgery, you need to seek as much information as possible from the doctor. Also ask the doctor about the chances of success and the costs involved.

In addition, the results of LASIK surgery on each person can be different. If you still have questions or are planning to have LASIK surgery, you should consult with an ophthalmologist first to make sure that you are a good candidate for this surgery.
