Laser eye surgery refers to a series of surgical procedures that change the shape of the cornea, the optical lens of the eye, or correct the lens inside the lens.
Laser eye surgery refers to a series of surgical procedures that change the shape of the cornea, the optical lens of the eye, or correct the lens inside the lens. Laser eye surgery usually:
- Myopia: Inability to see distant objects clearly
- Hyperopia: Inability to see close objects clearly
- Astigmatism: Irregular corneal shape
It is used to treat eye problems such as:
How is Laser Eye Surgery Performed?
Examination and Evaluation in Laser Eye Surgery
Before laser eye surgery, an ophthalmologist—usually a refractive surgeon or ophthalmologist—will examine your eyes thoroughly. The condition of your eye, corneal thickness and severity of your eye problem are evaluated. This evaluation process helps determine which laser eye surgery method is best for you.
Anesthesia in Laser Eye Surgery
The anesthesia used during laser eye surgery is usually applied to the eye in the form of local anesthetic drops. This will numb your eye and prevent pain.
Cornea Preparation for Laser Eye Surgery
Different laser eye surgery methods, such as LASIK, PRK, LASEK, SMILE, each use different procedures to change the shape of the cornea. Depending on the type of procedure, the upper layer of the cornea may be removed or preserved. This involves creating an area where the tissue beneath the cornea will be shaped with a laser.
Laser Shaping in Laser Eye Surgery
The critical stage of the surgery is the stage in which the laser is used. The laser carefully reshapes the shape of the cornea. This is done for the purpose of treating myopia, hyperopia or astigmatism. Laser shaping is computer-controlled and performed according to the parameters predetermined by the surgeon.
Flap Creation in Laser Eye Surgery
Some laser eye surgeries, such as LASIK, involve creating a flap (lid) on the top layer of the cornea. This flap is removed during the laser shaping process and placed back in place at the end of the procedure. This provides a feature that accelerates the healing process.
Closure and Recovery in Laser Eye Surgery
Once the laser shaping is complete, the doctor will replace the flap if necessary and cover your eye with a sterile bandage or protective lens. Your eye begins to enter the healing process.
What is the Recovery Process in Laser Eye Surgery?
The recovery process for each laser eye surgery is different. Usually, patients can return to normal activities within a few days. However, full recovery may take several weeks or longer. Your doctor monitors the healing process and performs regular check-ups.
Laser eye surgeries are an effective method to treat your eye problem and give you clearer vision. However, the success of the surgery and the risks of complications depend on the surgeon’s experience, the condition of your eye, and post-procedure care. It is important to meet with an ophthalmologist for more information about the procedure and to determine which surgery is right for you.
