LASIK Surgery

How does laser surgery correct accommodation problems?

Laser surgery, specifically LASIK (Laser-Assisted in Situ Keratomileusis) surgery, can correct certain accommodation problems by reshaping the cornea, which is the transparent front part of the eye. Accommodation refers to the ability of the eye to change focus and maintain clear vision at varying distances.

In cases where a person has a refractive error, such as myopia (nearsightedness), hyperopia (farsightedness), or astigmatism, the cornea does not refract light properly, leading to blurry vision. LASIK surgery aims to correct these refractive errors and restore clear vision.

During LASIK surgery, a specialized laser is used to reshape the cornea, altering its curvature and therefore its refractive power. The surgery begins with the creation of a thin flap on the surface of the cornea. This flap is then lifted, exposing the underlying corneal tissue.

The laser, guided by a computer and based on the individual’s eye measurements, emits pulses of ultraviolet light to remove very thin layers of tissue from the cornea. The laser’s precise and controlled removal of corneal tissue aims to reshape it, correcting the refractive error causing accommodation problems.

In the case of myopia, the cornea is made flatter to reduce its refractive power, allowing light to focus correctly on the retina. For hyperopia, the cornea is made steeper to increase its refractive power, enabling light to focus correctly on the retina. Astigmatism is corrected by reshaping the cornea to a more symmetrical and regular shape.

After the laser treatment, the corneal flap is repositioned, acting as a natural bandage and promoting healing. The cornea typically adheres without the need for stitches, thanks to its natural adhesion properties. Over time, the cornea stabilizes, and patients typically experience improved vision.

It’s important to note that LASIK surgery is not suitable for all accommodation problems. It is typically recommended for individuals with stable refractive errors who have sufficient corneal thickness. Other factors, such as the patient’s age, overall eye health, and other potential contraindications, also need to be considered before undergoing LASIK surgery.

It is essential to consult with an ophthalmologist or eye surgeon who specializes in refractive surgery to determine if LASIK or any other type of laser surgery is appropriate for your specific accommodation problem.
