Laser In Situ Keratomileusis, commonly known as LASIK, is a revolutionary eye surgery that has transformed the lives of millions by correcting vision issues like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. As one of the most popular and effective forms of refractive surgery, LASIK offers a potentially life-changing solution for those who want to reduce their dependence on glasses or contact lenses. 

This comprehensive guide will provide information about what LASIK entails, how it works, its benefits, and risks, and what to expect before, during, and after the procedure.

What is LASIK?

LASIK is a type of refractive eye surgery in which the cornea, the clear front section of the eye, is reshaped to allow light entering the eye to be correctly focused onto the retina, resulting in clearer vision. The treatment entails producing a tiny flap in the cornea, lifting it to allow precise excision of corneal tissue with an excimer laser, and repositioning the flap. 

How LASIK Works

Pre-Surgery Preparation

Before the surgery, a thorough eye examination is conducted to ensure the patient is a suitable candidate for LASIK. This includes measuring corneal thickness, pupil size, refractive errors, and eye health. Patients are typically advised to stop wearing contact lenses for a few weeks before the examination as lenses can alter the shape of the cornea.

Creating the Corneal Flap

During the surgery, the surgeon creates a thin, circular flap in the cornea using a femtosecond laser or a microkeratome. This flap is then gently folded back to access the underlying cornea.

Reshaping the Cornea

An excimer laser, which is a cool ultraviolet light beam, is used to remove microscopic amounts of tissue from the cornea. This reshaping process helps to refocus light entering the eye for improved vision.

Repositioning the Flap

After reshaping the cornea, the flap is gently reinserted to cover the area where the corneal tissue was removed. The cornea naturally adheres to the flap without the need for stitches.

Benefits of LASIK

Quick and Painless: LASIK is a relatively quick procedure, often completed within 30 minutes for both eyes. Most patients report minimal discomfort.

Immediate Results: Many patients notice improved vision immediately after the surgery, with vision typically stabilizing within a few days.

Long-Lasting Effects: LASIK offers a permanent correction for most patients, though some might need a touch-up procedure years later.

Reduced Dependence on Corrective Lenses: The primary benefit of LASIK is the significant reduction or complete elimination of the need for glasses or contact lenses.

Risks and Considerations

While LASIK is generally safe, it’s essential to be aware of potential risks and complications, which include:

Dry Eyes: Some patients experience dry eyes after LASIK, which can usually be managed with artificial tears or other medications.

Flap Complications: Issues with the corneal flap can arise during or after surgery, though they are rare.

Under or Overcorrections: In some cases, the laser may remove too much or too little corneal tissue, necessitating additional surgery.

Visual Disturbances: Some patients report glare, halos, or double vision, particularly in low-light conditions.

Who is a Good Candidate?

Not everyone is an ideal candidate for LASIK. Suitable candidates typically:

• Are over 18 years old
• Had a consistent prescription for vision care for a minimum of a year. 
• Have healthy eyes free of conditions such as glaucoma or cataracts
• Have sufficient corneal thickness
• Recovery and Aftercare

In addition to the above, post-surgery, patients are advised to rest and avoid strenuous activities for a few days. It’s normal to experience mild discomfort and blurry vision initially. Most people can return to work and resume normal activities within a couple of days. Regular follow-up visits with the surgeon are crucial to ensure proper healing and optimal vision results.

Frequently Asked Questions

What is LASIK and how does it work?

LASIK (Laser In Situ Keratomileusis) is a popular laser eye surgery used to correct vision problems such as myopia, hyperopia, and astigmatism. The procedure involves reshaping the cornea using a specialized laser, allowing light entering the eye to be properly focused onto the retina, resulting in clearer vision.

Who is a good candidate for LASIK?

Good candidates for LASIK are typically adults over the age of 18 with stable vision prescriptions for at least a year. They should have healthy eyes without conditions such as glaucoma, cataracts, or severe dry eye. A comprehensive eye examination by an eye care professional is essential to determine eligibility.

What can I expect during the LASIK procedure?

During the LASIK procedure, an eye surgeon uses a femtosecond laser to create a thin flap in the cornea. The flap is subsequently lifted, and the underlying corneal tissue is reshaped using an excimer laser. The flap is then adjusted and attaches spontaneously, eliminating the need for stitches. The total operation normally lasts about 15 minutes per eye. 

Is LASIK painful?

LASIK is generally not painful due to the use of numbing eye drops applied before the procedure. Patients may feel some pressure during the creation of the corneal flap but no significant pain. After the surgery, some discomfort or mild irritation is normal, but it typically subsides within a few hours to a few days.

What is the recovery process like after LASIK surgery?

Recovery from LASIK surgery is relatively quick. The majority of individuals report an improvement in their vision within 24 hours. It’s common to experience some blurred vision and fluctuations in vision clarity for a few days. It’s important to follow post-operative care instructions, which may include using prescribed eye drops, avoiding strenuous activities, and protecting the eyes from water and dust.

Is there any risk or adverse effect related to LASIK? 

As with any surgical procedure, LASIK carries some risks and potential side effects. Common side effects include dry eyes, glare, halos around lights, and fluctuating vision. The majority of adverse effects are transient and resolve within a few weeks to months. Serious complications are rare but can include infection, significant vision loss, or problems with the corneal flap.
