Eye surgery encompasses a wide range of procedures. However, focusing on LASIK, a common type of refractive surgery, here’s how it's typically performed:
LASIK (Laser-Assisted In Situ Keratomileusis) aims to correct refractive errors like nearsightedness, farsightedness, and astigmatism.
Here's a breakdown:
LASIK Eye Surgery Explained
LASIK eye surgery involves reshaping the cornea to correct vision.
The Steps Involved:
-
Flap Creation: According to the provided reference (A), the eye surgeon creates a thin, circular flap in the cornea. The cornea is the clear, dome-shaped front surface of the eye, responsible for much of the eye's ability to focus light.
-
Corneal Reshaping: The surgeon then uses a specialized laser to reshape the cornea underneath the flap (B). This reshaping corrects the refractive errors, allowing light to focus properly on the retina.
-
Flap Repositioning: After reshaping the cornea, the flap is carefully repositioned back into its original position. It naturally adheres to the underlying corneal tissue without the need for stitches.
Summary Table
| Step | Description |
|---|---|
| Flap Creation | A thin flap is created in the cornea, exposing the underlying tissue. |
| Corneal Reshaping | A laser precisely reshapes the cornea to correct refractive errors, improving focus. |
| Flap Repositioning | The corneal flap is carefully repositioned, adhering naturally without stitches. This allows the cornea to heal and stabilize. |
This entire procedure aims to improve vision by addressing the underlying refractive issues in the eye.
