Eye laser surgery, typically referring to procedures like LASIK, reshapes the cornea using a laser to correct vision. The procedure uses local anaesthetic eye drops and takes around 5 minutes per eye.
The Process of Eye Laser Surgery
Here's a general overview of how eye laser surgery is performed:
-
Anesthesia: The eye is numbed using local anesthetic eye drops to minimize discomfort during the procedure.
-
Corneal Flap (for LASIK): In LASIK (Laser-Assisted In Situ Keratomileusis), a thin flap is created on the cornea. This flap is then gently folded back to expose the underlying corneal tissue. Note that some procedures, like PRK, do not require a flap.
-
Laser Reshaping: A precise excimer laser then reshapes the cornea. The diameter of the laser beam and the number of pulses that are directed onto the cornea are carefully controlled using computer technology, so that the surface of the cornea is reshaped. This reshaping corrects the refractive error (nearsightedness, farsightedness, or astigmatism).
-
Flap Repositioning (for LASIK): After the cornea is reshaped, the corneal flap (in LASIK) is carefully repositioned back into its original position. It naturally adheres without the need for stitches.
-
Recovery: The recovery process varies depending on the specific procedure, but typically involves using prescribed eye drops and following post-operative instructions to promote healing.
Key Aspects of the Procedure
Here's a breakdown of important aspects to consider:
- Precision: Computer-guided lasers ensure extreme accuracy in reshaping the cornea.
- Speed: The laser treatment itself is relatively quick, often taking only seconds.
- Customization: The laser treatment is customized to each patient's individual refractive error.
Benefits of Laser Eye Surgery
The primary benefit of eye laser surgery is improved vision, potentially reducing or eliminating the need for glasses or contact lenses.
