The LASIK procedure is remarkably precise and typically takes less than 10 minutes. Here’s a step-by-step breakdown of the process:
Creating a Corneal Flap
The procedure begins with the creation of a thin flap on the cornea’s surface. This flap is created using either a microkeratome (a surgical blade) or a femtosecond laser. The flap is gently lifted to expose the underlying corneal tissue.
This step is critical because it allows the surgeon to reshape the cornea without damaging the outer layers of the eye, resulting in faster healing and less discomfort for the patient.
Reshaping the Cornea
Once the flap is lifted, an excimer laser—a highly precise, computer-controlled device—is used to reshape the cornea.
For nearsightedness: The laser flattens the cornea to reduce its curvature, allowing light to focus correctly on the retina.
For farsightedness: The laser steepens the cornea by removing tissue from its outer edges.
For astigmatism: The laser smooths out irregularities in the cornea’s shape.
The excimer laser uses cool ultraviolet light to remove microscopic amounts of tissue with extraordinary accuracy, ensuring the cornea is reshaped to the exact specifications determined during pre-surgery testing.
Repositioning the Flap
After the cornea has been reshaped, the surgeon carefully repositions the corneal flap. The flap adheres naturally without the need for stitches, creating a protective layer that helps the eye heal quickly.
Why LASIK Is So Precise
One of the reasons LASIK is so effective is its reliance on advanced diagnostic and treatment technologies:
Wavefront-guided technology: This creates a detailed 3D map of the eye, allowing the surgeon to customize the procedure to the patient’s unique visual imperfections, even those that can’t be corrected with glasses or contacts.
Eye-tracking systems: These ensure the laser remains precisely focused on the eye, even if the patient moves slightly during the procedure.
These innovations contribute to LASIK’s high success rate, with the vast majority of patients achieving 20/20 vision or better after surgery.
The Science of Healing and Long-Term Results
One of LASIK’s advantages is its quick recovery time. Most patients notice improved vision within 24 hours, and full healing occurs within a few weeks. The corneal flap acts as a natural bandage, protecting the eye as it heals.
Over time, the reshaped cornea provides a stable foundation for clear vision. Studies show that LASIK results are highly durable, with many patients enjoying perfect or near-perfect vision for decades after the procedure.
