LASIK stands for Laser-Assisted In Situ Keratomileusis in its complete form. A laser is used during LASIK to correct refractive errors and enhance or improve eye vision. A unique tool called a microkeratome is utilized in LASIK to cut a tiny flap on the cornea’s surface. The cornea is reshaped with the laser to improve vision after a flap is created.
After obtaining the correct shape, the surgeon will put the flap back on the corneal surface. In this process, no sutures are needed, and the cornea’s surface heals on its own in a matter of days or weeks.
Wave-optimized LASIK employs precise corneal curvature measurements to lessen the eye’s spherical aberrations. The goal of this procedure is to maintain the eye’s original spherical form. LASIK surgery aids in reducing a person’s dependence on eyeglasses or contact lenses. It aids in treating astigmatism, hyperopia, and myopia in people.
The safe process for LASIK eyesight correction. No medical instruments, such as blades, scissors, or stitches, are utilized. A skilled eye expert performs it using a laser and other surgical mechanic instruments.
How is the LASIK procedure carried out?
The main goal of this straightforward operation is to alter their cornea’s shape to correct their eyes’ refractive defect. A laser with cold ultraviolet rays will be used throughout the treatment to reshape the cornea by removing small amounts of tissue. The eye surgeon removes a little hinged flap from the front of the eye using a tiny blade or cutting laser. The doctor may reach the cornea area that must be reshaped by folding the flap.
The doctor reshapes a portion of the cornea using a laser that has been designed. A minimal quantity of corneal tissue is eliminated with each laser pulse. The surgeon repositions the flap after shaping the cornea. Usually, the flap heals without needing sutures.
The patient will be instructed to concentrate on the point of light during the procedure. Visitors may keep one eye fixed while the laser reshapes their cornea by focusing on this light. As the laser destroys unwanted hair, visitors could notice a unique odour. Patients can see a unique scent as the laser removes the corneal tissue.
What can patients expect during their Lasik eye surgery?
- Before the surgery
If you want your lasik surgery to have long-term effects, then your doctor must evaluate you properly before the surgery to ensure that you are a good candidate.
When a doctor conducts your medical evaluation before the surgery, then they ask questions about your surgical and medical history, and you will also go through a detailed eye examination, so there is no need to worry about it; this is only done for the evaluation of your vision, and it is essential for the safety of your eyes during the lasik procedure.

The lasik surgery procedure does not take more than 30 minutes to complete. The patient has to lie on the back of a reclining chair for the design, and they are provided with medicine which helps them to relax. Then some numbing drops are used for the eyes, and an instrument is used by the doctor who helps keep the patient’s eyelids open.
After that, a suction ring is placed in the eyes of the patient before the doctor goes to cut the corneal flap. This process may feel like a little bit of pressure on the eyes, but it’s nothing more than that, and then the patients’ vision may feel dim. Doctors take the help of a small baled or a cutting laser to cut the small hinged flap away from your front eyes. When the flap is folded towards the back, the surgeon gets access to the cornea parts that will be reshaped.
With the help of a programmed laser, the surgeon can complete the process by reshaping the required parts of the cornea. A very tiny amount of corneal tissue is removed with every laser beam pulse. When the cornea’s reshaping is completed, the surgeon places the flap back in its place. There is no need for stitches in the healing process of the flap. The patients are asked to focus on a single light point during the surgery.
- After the surgery
When the surgery is completed, the patients may feel some burning sensation or itchiness in their eyes, but it is normal. There is no need for any worry. Patients may also feel that their vision is a little bit blurry, but it all recovers with time, generally very quickly.
The patient is provided with some medications which help them with the aftermath of the surgery, such as keeping them comfortable for a long time after the surgery. The patient also has to wear a shield over their eyes which protects them at night while sleeping and also help in the process of healing the eyes.
