How does LASIK surgery improve vision?

LASIK is a revolutionary eye surgery that has transformed the lives of millions. By reshaping the cornea, it corrects common vision problems and provides clearer sight. But how exactly does LASIK work, and why is it so effective? Understanding how LASIK improves vision can help you decide if this procedure is right for you.

What is LASIK?

Le LASIK, ou Laser-Assisted In Situ Keratomileusis, est une chirurgie réfractive qui remodèle la cornée, la partie avant et transparente de l'œil. Il corrige des problèmes de vision tels que la myopie, l'hypermétropie et l'astigmatisme en modifiant la façon dont la lumière se concentre sur la rétine.

How Does LASIK Work?

1. Precise Corneal Reshaping

LASIK uses a high-precision laser to reshape the cornea. Here’s how it works:

• Step 1: Creating a Corneal Flap: The surgeon creates a thin flap on the surface of the cornea using a laser or microkeratome blade. This flap is gently lifted to expose the underlying corneal tissue.
• Step 2: Reshaping the Cornea: A laser, often an excimer laser, reshapes the exposed corneal tissue to correct the specific vision issue. The laser is programmed based on precise measurements of your eye to ensure accuracy.
• Step 3: Replacing the Flap: The flap is carefully repositioned, acting as a natural bandage. It adheres without stitches and promotes quick healing.

2. Correcting Vision Problems

The effectiveness of LASIK comes from its ability to reshape the cornea to correct how light is focused on the retina:

• Myopia: For nearsighted individuals, the cornea is reshaped to be flatter, allowing light to reach the retina correctly.
• Hyperopia: For farsighted individuals, the cornea is reshaped to be steeper, focusing light accurately.
• Astigmatism: The procedure smooths out irregularities in the cornea’s shape, allowing for clearer vision.

What to Expect During LASIK

LASIK is a straightforward and quick procedure, often completed in under 30 minutes for both eyes. Here’s what you can expect:

• 1. Pre-surgery Preparation Before the surgery, your eyes will be numbed with anaesthetic eye drops. This ensures you remain comfortable throughout the procedure. The surgeon may place a device to keep your eyelids open.
• 2. The Procedure Itself The creation of the corneal flap and the reshaping of the cornea are done with minimal discomfort. Most patients report feeling slight pressure but no pain.
• 3. Post-surgery Recovery After the procedure, you might experience mild discomfort, dryness, or sensitivity to light for a few days. Most people notice improved vision within 24 to 48 hours, with full recovery in about a week. Your surgeon will provide aftercare instructions to promote healing and minimise risks.

The Benefits of LASIK Surgery

Choosing LASIK comes with numerous advantages:

• 1. Quick Results Most patients experience improved vision within a day or two. The recovery is fast, allowing you to resume daily activities shortly after the surgery.
• 2. Long-lasting Vision Correction For many, LASIK offers permanent results. While vision may change slightly with age, most patients maintain improved vision for years without needing additional procedures.
• 3. No More Dependence on Glasses or Contacts
  LASIK can eliminate or significantly reduce the need for glasses or contact lenses, providing freedom and convenience in daily life.
• 4. Enhanced Quality of Life Clear vision can make everyday tasks easier, from driving to enjoying sports or other hobbies. LASIK helps improve overall quality of life by providing reliable, unaided vision.

Who is a Good Candidate for LASIK?

While LASIK is effective, it’s not suitable for everyone. Good candidates typically:

• Are over 18 years old with a stable prescription for at least a year.
• Have healthy eyes without conditions like severe dry eye syndrome or keratoconus.
• Have adequate corneal thickness to support the reshaping process.
• Understand the potential risks and have realistic expectations.
