LASIK, which stands for laser in-situ keratomileusis, is a type of refractive eye surgery that corrects vision problems such as farsightedness, nearsightedness, and astigmatism.

In people who have normal vision, the cornea refracts light accurately onto the retina at the back of the eye. But for people who have farsightedness (hyperopia), nearsightedness (myopia), or astigmatism, the light is bent incorrectly. This happening results in blurred vision.

Glasses or contact lenses can fix these vision problems. However, during LASIK surgery, a particular type of cutting laser is used precisely to reshape the cornea so that it refracts light correctly. Therefore, it can be a great alternative to glasses or contact lenses.

Ideal applicants for LASIK surgery may include:

  • Individuals in good health with healthy eyes
  • Individuals who have had a stable prescription for about a year
  • Patients with up to -11.00 diopters of nearsightedness, up to +5.00 of farsightedness, or up to 5.00 of astigmatism
  • Individuals who do not want to wear glasses or contact lenses anymore
  • Athletes or active professionals who are looking to dispense with the inconvenience involved in glasses and contact lenses

However, LASIK surgery may not be suitable for people who are:

  • younger than 18
  • pregnant or nursing
  • take certain medications
  • have a lot of recent changes to their vision prescription
  • have uneven or thin corneas
  • have dry eyes or have eye conditions such as glaucoma
  • have other health issues such as rheumatoid arthritis, diabetes, or lupus 

Treatment Duration:

LASIK eye surgery takes typically about 10-30 minutes. However, the duration of this surgery depends on individual circumstances and can vary slightly from patient to patient.

Recovery Time:

Patients can leave the clinic 10-15 minutes after their surgery, and they can return to work after 24 hours or within a few days, depending on their healing process. Complete recovery and vision stabilization can take between two or three months.

Right after the surgery, your eye might itch, be watery and feel gritty. Also, you will probably have blurred vision and some minor pain. Therefore, your eye doctor may prescribe pain medication or eye drops for you. Also, you might be asked to wear a shield over your eye at night until your eye heals completely.

It might take a few weeks so that you can start to use cosmetics around your eyes. You probably should wait some weeks before continuing swimming, strenuous contact sports, or using hot tubs, based on your doctor’s recommendations.

Potential Risks and Side Effects:

Although complications resulting in a loss of vision are rare, specific side effects of LASIK eye surgery, such as dry eyes and temporary visual problems, are relatively common. However, these problems usually fade away after a few weeks or months, and very few people consider them to be long-term problems.

Risks associated with LASIK surgery include:

  • Dry eyes
  • Glare, halos and double vision
  • Undercorrections
  • Overcorrections
  • Astigmatism
  • Flap problems
  • Regression
  • Vision loss or changes (very rare)

Note: Some health conditions can increase the risks associated with LASIK surgery, including:

  • Autoimmune disorders, such as rheumatoid arthritis
  • A weak immune system caused by HIV or taking immunosuppressive medications
  • Persistent dry eyes
  • Any recent changes in vision due to hormonal changes, medications, pregnancy, breast-feeding or age
  • Lid disorders
  • Inflammation of the cornea
  • Eye diseases, such as uveitis, herpes simplex affecting the eye area, glaucoma or cataracts

LASIK surgery is usually not advisable if you:

  • Have an eye disorder that causes the cornea to become thin and bulge, or if you have a family history of this problem
  • Have a reasonably good overall vision
  • Have severe nearsightedness
  • Participate in contact sports that may be associated with blows to the face
  • Have huge pupils or thin corneas
  • Have age-related eye changes that cause vision to be less clear

How Does LASIK Surgery Work?

This type of refractive eye surgery is a relatively quick and straightforward procedure. LASIK surgery is usually completed in 30 minutes or less. Below, we have outlined a step-by-step guide to this procedure.

  1. Pain-Numbing Eye Drops

First, numbing eye drops are administered to your eyes. The effect of these eye drops lasts for the duration of the procedure.

  1. Flap Creation

Then, your doctor places a vacuum ring on the eye to prop it open and hold it in position. This suction ring may cause a slightly strange sensation, but you will not have a feeling of pain. You are asked to focus on a laser point or a light to keep your eye steady. The light will typically include a tracking mechanism so that the ophthalmologist will be aware of when the eye moves from this point and also pause the treatment to give the patient a chance to re-focus on a single point again.

After that, your ophthalmologist creates and folds the flap via precision instruments. Your vision will blur, dim, or even fade entirely during this step, but it should revert to the normal state as soon as the flap is created.

  1. Corneal Shaping

After creating the flap, an excimer laser removes tissue from the cornea to form a new shape as well as refractive properties. The amount deducted will be based on the preoperative evaluation that your ophthalmologist carries out.

  1. Flap Sealing

When the process of the cornea reshaping is completed, the ophthalmologist will replace the flap and let natural tension hold it in place till an initial surface healing occurs.

What Are the Different Types of LASIK Surgery Available?

There are three main types of LASIK surgery available. The one that you undergo depends on your situation and your ophthalmologist’s recommendation.

  • Traditional LASIK

This is the most popular type of LASIK surgery. It includes the previously explained steps above, using a microkeratome blade for creating the first flap.

  • IntraLASIK

In this technique, the flap is created using a femtosecond laser instead of the microkeratome blade.

The laser is computer-guided and provides a level of accuracy above the traditional method. Also, the risk of certain complications is lower, making it suitable for several candidates to undergo the procedure.

  • Custom LASIK

This technique is the most advanced method of LASIK eye surgery. It creates a detailed 3D map of the eye via wavefront technology, allowing the ophthalmologist to tailor the surgery for each patient. Moreover, custom LASIK can resolve higher-order aberrations that were previously untreatable using either conventional LASIK surgery or corrective lenses.

You should discuss with your ophthalmologist and then decide what kind of approach is most suitable for you to balance risk, cost, and potential rewards.
