What is Lasik Surgery?

LASIK surgery (Laser-Assisted In Situ Keratomileusis) is a popular laser eye surgery designed to correct refractive errors such as nearsightedness, farsightedness, and astigmatism. This laser surgery reshapes the cornea, allowing light to focus correctly on the retina, leading to improved vision without the need for glasses or contact lenses.

Many people opt for laser eye surgery due to its effectiveness, quick recovery time, and minimal discomfort. If you’re considering LASIK eye surgery, understanding the procedure, benefits, and risks is essential before making a decision.

Which Type of Eye Conditions Does LASIK Treat?

  • Nearsightedness (Myopia)

People with myopia have difficulty seeing distant objects clearly. LASIK surgery for eyes corrects this condition by reshaping the cornea to allow light to focus properly.

  • Farsightedness (Hyperopia)

Individuals with hyperopia struggle to see close objects. Laser eye surgery adjusts the corneal shape to enhance near vision.

  • Astigmatism

Astigmatism occurs due to an irregularly shaped cornea, causing blurred vision. LASIK surgery smooths out these irregularities, ensuring sharper vision.

 

How to Prepare for LASIK Surgery

Preparation is crucial for a successful LASIK eye surgery procedure. Here’s what to do:

  • Stop wearing contact lenses for at least two weeks before surgery to allow your cornea to return to its natural shape.

  • Schedule a comprehensive eye exam to ensure you are a suitable candidate for laser surgery.

  • Avoid applying eye makeup or creams on the day of surgery to minimize infection risk.

  • Follow your doctor’s instructions regarding medication and pre-surgery care.

 

LASIK Surgery Procedure

The LASIK eye surgery procedure is quick and typically completed within 30 minutes. Here’s how it works:

  • Numbing drops are applied to prevent discomfort.

  • A thin corneal flap is created using a femtosecond laser or microkeratome.

  • The cornea is reshaped using an excimer laser, correcting refractive errors.

  • The flap is repositioned, allowing natural healing to occur.

 

Most patients notice improved vision within a few hours after the surgery.

 

LASIK Surgery Side Effects

While LASIK surgery for eyes is highly effective, some individuals may not be suitable candidates, including:

  • People with thin corneas – A thin cornea may not support the necessary reshaping.

  • Patients with severe dry eyes – Existing dryness can worsen after surgery.

  • Individuals with unstable vision – If your prescription changes frequently, LASIK may not be suitable.

  • People with certain medical conditions – Autoimmune diseases can affect healing post-surgery.

 

LASIK Surgery Recovery Time

Recovery from LASIK eye surgery is typically fast. Here’s what to expect:

  • First 24 hours – Mild discomfort, blurry vision, and sensitivity to light.

  • 1 week – Significant vision improvement, but avoid strenuous activities.

  • 1 month – Vision stabilizes, and most restrictions are lifted.

  • 3-6 months – Full recovery, with optimal vision results.

 

Risks of LASIK Surgery

Although LASIK surgery is generally safe, it’s important to be aware of potential risks:

  • Under-correction or over-correction – Some patients may still need glasses after surgery.

  • Infection or inflammation – Rare but possible side effects.

  • Night vision disturbances – Halos, glare, or starbursts around lights.

  • Flap complications – Issues related to the corneal flap created during surgery.

 

LASIK surgery is a highly effective solution for those seeking to correct refractive errors and reduce dependence on glasses or contacts. Understanding the LASIK surgery procedure, potential LASIK surgery side effects, and LASIK surgery recovery time can help you make an informed decision. If you’re considering laser eye surgery, consult an experienced ophthalmologist to determine whether it’s the right choice for you.

Frequently Asked Questions (FAQs) about Lasik Surgery

Does laser eye treatment or vision correction last a lifetime?

There is no age limit for LASIK, and the surgery depends on the eye health of the individual, in addition to the visual needs. Patients with no organic reason for vision loss, such as cataracts or other medical complications, can easily go for a LASIK surgery. 

Immediately after LASIK treatment, the eyes may itch or burn or feel like something is stuck in the eye. There can be a certain level of discomfort and mild pain in some cases. The doctor may suggest a mild pain-relieving medicine for the same. The vision can be blurred or hazy.

Laser eye operation for cataracts is a viable option since it helps rectify the refractive errors by reshaping the cornea using a laser. However, in mtoto wa jicho cases, LASIK will not correct the blurred vision caused by this disorder. 

Some people have a blurred vision right from birth due to some congenital disabilities, while others have developed a blurred vision with time. In some cases, blurry vision can be rectified with the help of LASIK eye treatment or surgery. 

In this type of procedure, the tissues of the corneal surface are removed from the corneal surface (front part of the eye), which helps maintain the effects for a lifetime and are, therefore, permanent. The surgery helps with the correction of refractive error and clarity of vision.

Contrary to public notion, LASIK is not a very costly treatment. It is imperative to keep in mind that laser eye surgery price can vary due to different factors like infrastructure, technology, equipment, ranging from Rs. 25000 to Rs. 100000.
