What Is Lasik Eye Surgery?


Today, 75% of adults need vision correction, and nearly 65% wear glasses. However, many people wearing glasses feel that it makes them unattractive. In addition, some find it hard to select frames that suit their appearance. Meanwhile, wearing contact lenses is an alternative to glasses, but it needs more maintenance and is not convenient to wear at all times. In the meantime, Lasik eye surgery corrects defective vision and helps people have perfect vision without using glasses or contact lenses.

What Is Lasik Surgery?

Lasik stands for “laser in-situ keratomileusis”, and the surgery is used to correct vision problems like nearsightedness, farsightedness and astigmatism. The surgery uses a laser to reshape the cornea to focus the light on the retina. Little or no pain is involved with Lasik surgery, and people won’t need glasses or contact lenses after the surgery. The surgery is completed in less than 30 minutes, and patients see immediate results after the surgical procedure. In addition, people recover quickly after the surgery and return to normal activities after a day’s rest.

Who Can Have Lasik Surgery?

People with farsightedness: People with farsightedness or hyperopia can see objects in the distance clearly, but things that are closer appear blurry. It is caused when the curvature of the cornea becomes flat, and Lasik surgery reshapes the cornea to bring a steeper curve.

People with nearsightedness: People with nearsightedness or myopia can see objects near them clearly, but distant objects appear blurred. It happens when the curvature of the cornea is too steep, and Lasik surgery corrects the curvature of the cornea and restores clear vision.

Astigmatism: People with astigmatism have a different eye shape. The cornea’s curvature is irregular, and laser surgery corrects the curvature.

Who Cannot Have Lasik Surgery?

  • People younger than 18 years old.
  • Pregnant or nursing women.
  • People with thin or uneven corneas.
  • People with eye conditions like dry eyes and glaucoma.
  • People with health issues like diabetes, cataract and arthritis.
  • For people who have autoimmune disorders, the healing process is challenging.

Post-Surgery Eye Care Tips

  • The eyes need plenty of rest after the surgery to allow them to heal.
  • Eyes should be protected from harsh sunlight using dark sunglasses.
  • People must avoid dusty and smoky environments.
  • People need to wear protective eye shields for a few nights while sleeping.
  • Eyes must be lubricated using preservative-free artificial tears.

Benefits of Lasik Surgery

Instant results: People get a perfect vision when the surgery is completed. They need not wear glasses or contact lenses but experience clear vision.

Almost painless: Compared to other surgeries, there is less or no pain associated with Lasik surgery. Many people do not experience any pain or discomfort after the surgery.

Quick recovery period: The recovery period after the surgery is significantly less because no stitches are involved in this surgery. Only a few people have slight irritation in the eyes for a few days.

Less risk: Lasik surgery is a technologically advanced procedure with no risks and fewer chances for vision impairment. Post-operative care is also not challenging, and there are minimal chances for infections.

Easy life: Lasik surgery makes life easy for people. They need not worry about carrying their spectacle case, lens case and solution with them all time. As such, travelling becomes easy, and the vision is also clear.

Vision stabilises within six months of Lasik eye surgery. As such, some patients see clearly after the surgery, and a few may take 2 – 5 days to recover. However, people are happy with the surgery results because they have clear vision without using glasses or contact lenses.
