What is Lasik Eye Surgery?
LASIK eye surgery is a type of refractive surgery that aims to correct vision problems such as nearsightedness, farsightedness, and astigmatism. LASIK, which stands for Laser-Assisted in Situ Keratomileusis, is a popular elective procedure that has helped millions of people around the world improve their vision.
In this article, we’ll take a closer look at what LASIK eye surgery is, how it works, and who is a good candidate for the procedure. We’ll also discuss the benefits and risks of LASIK, as well as what to expect during the recovery period.
LASIK Eye Surgery
LASIK eye surgery is a type of refractive surgery that uses a laser to reshape the cornea, which is the clear front surface of the eye. By reshaping the cornea, LASIK can help to improve the way that light enters the eye, allowing it to focus properly on the retina at the back of the eye.
LASIK is a popular choice for people who suffer from vision problems such as nearsightedness, farsightedness, and astigmatism. Nearsightedness, also known as myopia, occurs when the eye is too long, causing light to focus in front of the retina. Farsightedness, or hyperopia, occurs when the eye is too short, causing light to focus behind the retina. Astigmatism is a condition in which the cornea is irregularly shaped, causing blurred vision.
How Does LASIK Eye Surgery Work?
LASIK eye surgery works by using a laser to create a thin flap in the cornea. The flap is then lifted, and a laser is used to reshape the cornea, allowing it to better focus light onto the retina. After the cornea has been reshaped, the flap is replaced, and the eye is allowed to heal.
There are several different types of lasers that can be used during LASIK eye surgery, including excimer lasers, femtosecond lasers, and wavefront-guided lasers. Excimer lasers use ultraviolet light to remove small amounts of tissue from the cornea, while femtosecond lasers use pulses of laser energy to create a precise incision in the cornea. Wavefront-guided lasers use advanced computer technology to create a custom treatment plan for each patient, taking into account the unique characteristics of their eyes.
Who is a Good Candidate for LASIK Eye Surgery?
Not everyone is a good candidate for LASIK eye surgery. The ideal candidate is someone who is over 18 years old and has stable vision. They should not have any underlying eye diseases or conditions, such as glaucoma or cataracts, that could affect the outcome of the procedure. They should also have a healthy cornea, with enough thickness to allow for the creation of a corneal flap.

In addition, the ideal candidate for LASIK should have a strong desire to reduce their dependence on glasses or contact lenses. While LASIK can help to improve vision, it is not a guarantee that a person will no longer need corrective lenses. Some people may still need to wear glasses or contacts after the procedure, albeit with a lower prescription.
It’s important to note that LASIK is not recommended for everyone. Women who are pregnant or nursing should not undergo LASIK, as hormonal changes can affect the stability of their vision. People with certain medical conditions, such as autoimmune diseases or diabetes, may also be advised against LASIK.
Benefits and Risks of LASIK Eye Surgery
The benefits of LASIK eye surgery are numerous. For many people, LASIK can provide a significant improvement in vision, allowing them to see more clearly without the need for glasses or contacts. The procedure is also relatively quick and painless, with most people experiencing only minor side effects.
