What is LASIK Surgery?

What is LASIK eye surgery?

LASIK eye surgery is a well-known and commonly utilized laser-based vision correction procedure. LASIK (laser-assisted in situ keratomileusis) is a surgery that can be used instead of glasses or contact lenses. A specific type of cutting laser is used to alter the shape of the translucent tissue at the front of the eye to improve vision (cornea).

Why is LASIK surgery done?

Any of the following visual issues can be corrected by LASIK surgery:

Nearsightedness, often known as myopia, occurs when light rays focus in front of the retina rather than on it. When the eyeball is particularly lengthy or the cornea curves too steeply, distant vision is obscured. Objects that appear to be close can be seen clearly, while those that appear to be far away are hazy.

When one has a shorter than average eyeball or an abnormally flat cornea, light focuses behind the retina rather than on it, causing farsightedness or hyperopia. At a distance, this causes hazy vision.

Astigmatism is a condition in which the cornea bends or straightens unevenly, causing near and far vision to be blurred.

People who already use glasses or contact lenses may pursue LASIK surgery, but only if the patient is a suitable fit for the procedure.

Why should one consult a doctor regarding LASIK surgery?

Patients who do not fit the criteria for LASIK surgery should speak with their eye doctor about other options. The doctor may ask some or all of the following questions to evaluate if LASIK eye surgery is the best option for the patient:

If you're under the age of 18,

If you're expecting a child or are breastfeeding one,

It is possible to use some pills or treatments if necessary.

If you've lately had a lot of changes to your vision prescription.

If your cornea is thin or irregular.

If your eyes are excessively dry.

If you have glaucoma, diabetes, lupus, or rheumatoid arthritis, you should see a doctor.

What are the potential risk factors associated with LASIK surgery?

The following are some of the most common risks connected with LASIK eye surgery:

Dry eyes — as the eyes heal, they may feel unusually dry during the first six months or more after surgery, and dry eyes can impair visual quality. To cure dry eyes, the eye doctor may prescribe eye drops.

Glare, halos, and double vision — Following surgery, the patient may experience difficulty seeing at night, which can last anywhere from a few days to several weeks. Light sensitivity improvements, glare, color fringing around bright lights, and double vision are all possible symptoms.

Under corrections - If the laser removes too little tissue from the eye, the needed sharper vision will not be achieved. Nearsighted individuals are more likely to require corrective lenses. Within a year, they may require another LASIK procedure to remove more tissue.

Overcorrections - Overcorrections occur when the laser burns away too much tissue in the eye. It's possible that overcorrections are more difficult to fix than under corrections.

Changes in vision or loss of vision - In rare situations, surgical complications might result in vision loss, and some people may not be able to see as clearly as they once could.

What can one expect from LASIK surgery?

Prior to the operation,

People who undergo a thorough examination prior to surgery to ensure that they are suitable candidates for the procedure reap the greatest long-term benefits from LASIK.

If you're wearing contact lenses, which can change the shape of your cornea, you'll need to take them out for at least a few weeks before the assessment and surgery and replace them with spectacles. In addition, the doctor will look for evidence of:

Eye infection

Inflammation

Dry eyes

High eye pressure

During the procedure

The LASIK process is completed in 30 minutes or less. For the procedure, the patient will be laying on their back in a recliner chair and may be given medicine to help them relax. Equipment is also used to keep the eyelids open after numbing drops have been placed in the eye. The eye surgeon then uses a small blade or cutting laser to remove a small hinged flap from the front of the eye, allowing the doctor to reach the corneal area that has to be adjusted by folding back the flap. In addition, the eye surgeon uses a controlled laser to shape parts of the cornea. The laser beam removes a little bit of corneal tissue with each pulse. The surgeon adjusts the flap after reshaping the cornea.

After the procedure

Right after the procedure, your eyes may itch, feel gritty, burn, or be watery, and your vision will most likely be blurred. In most situations, however, there will be little pain and the vision will recover quickly. The patient may be given pain medication or eye drops a few hours after the therapy to help them relax. The eye doctor may recommend wearing a mask over the eye at night until the eye heals.

LASIK surgery is generally not advisable if you:

Have a fairly good overall vision

Have age-related eye changes which causes vision to be less clear

Have an eye disease that may cause the cornea to bulge and thin, or if you have a family history of it

Have very large pupils or thin corneas

Have severe near-sightedness

Participate in contact sports that may be linked to blows on the face

Conclusion

LASIK can often provide better vision without the nuisance of wearing glasses or contact lenses. Following refractive surgery, you have a fair chance of regaining 20/25 vision or better. For the majority of their jobs, persons who have had LASIK refractive surgery do not need to wear glasses or contact lenses. The outcome is determined on your refractive error and other things.
