What Happens During LASIK Eye Surgery?

LASIK eye surgery is a common laser refractive surgery that helps to correct vision problems. LASIK is an alternative to glasses or contacts. During the surgery, a special laser is used to change the cornea’s shape to improve vision. The cornea is the dome-shaped part of the eye. 

When a person has normal vision, the cornea refracts or bends light directly on the retina. For someone with vision problems such as nearsightedness, farsightedness, or astigmatism, the light is bent, resulting in poor vision. 


Why LASIK Surgery Is Performed

LASIK surgery helps correct vision by reshaping the eye cornea. The procedure is used for correcting vision problems such as myopia or nearsightedness. The problem occurs when the eyeball is longer than it should be. It is also due to the cornea curving too sharply, causing light rays to focus incorrectly. 

Farsightedness or hyperopia can also be treated using LASIK. Someone with the condition has eyeballs that are shorter than normal or a cornea that is too flat. Astigmatism occurs when the cornea flattens or curves unevenly.


What to Expect Before LASIK

Before you undergo LASIK surgery, the doctor will carry out an evaluation or eye examination. This will help ensure that you are a good candidate for the procedure and enjoy long-term positive results. If you wear contacts, you will need to stop wearing them for some weeks before the surgery. 

During the evaluation, the eye doctor will provide specific guidelines on what you need to do before the surgery. A comprehensive eye exam will help determine whether you can undergo LASIK safely.


During LASIK Evaluation

During the evaluation for LASIK, the eye doctor will ask about your surgical and medical history. The doctor will evaluate the condition of your eyes, looking for signs of inflammation, an eye infection, or dry eyes. The doctor will also look for signs of large pupils and high eye pressure. 

The evaluation will also involve measuring the cornea, noting the contour, shape, thickness, and other irregularities. The doctor will check the parts of the cornea that need to be re-shaped and the amount of tissue to remove.


During LASIK Surgery

During the procedure, you will lie back in a reclining chair after receiving medication to help you relax. After applying numbing drops to the eye, the doctor will use an instrument to keep the eyelid open. A suction ring is placed on the eye before the corneal flap is cut. 

The surgeon uses a cutting laser or small blade to cut a small flap away from the eye. The flap is folded back to allow access to the cornea. The surgeon uses a programmed laser to reshape the cornea. After reshaping the cornea, the flap is put back into place.


Preparing for LASIK Surgery

There are several steps that you can take to prepare for LASIK surgery. The first is to find out the cost of the procedure. LASIK is considered to be elective surgery, so it is not usually covered by insurance. 

As you make an appointment for the surgery, be sure to make transport arrangements to and from the surgery. You may experience blurry vision soon after the procedure and feel the effects of the medication.
