Eye Surgery

What is laser eye surgery?

Laser eye surgery refers to a group of surgical procedures that use lasers to reshape the cornea, the clear front surface of the eye, in order to correct refractive errors and improve vision. The goal of laser eye surgery is to reduce or eliminate the need for glasses or contact lenses for people with nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. The most common types of laser eye surgery are LASIK (Laser-Assisted in Situ Keratomileusis) and PRK (Photorefractive Keratectomy).

​

Both LASIK and PRK procedures are outpatient surgeries that are performed under local anesthesia (numbing eye drops) and take only a short amount of time to complete. These procedures are highly effective in correcting refractive errors and can provide significant visual improvements. However, not everyone is a suitable candidate for these surgeries. Factors such as the stability of your prescription, corneal thickness, and overall eye health play a role in determining eligibility.

What are the different procedures available?

  1. LASIK (Laser-Assisted in Situ Keratomileusis):

    • In LASIK, a thin flap is created on the cornea using a femtosecond laser. This flap is then lifted to expose the underlying corneal tissue.

    • An excimer laser is used to reshape the cornea by removing a precise amount of tissue. The laser is guided by a computer program based on your specific eye measurements.

    • After the cornea is reshaped, the flap is repositioned, and it adheres naturally without the need for stitches.

    • LASIK typically results in rapid visual recovery and minimal discomfort.

  2. PRK (Photorefractive Keratectomy):

    • PRK involves removing the thin outer layer of the cornea, called the epithelium, to expose the underlying corneal tissue.

    • An excimer laser is then used to reshape the cornea by precisely removing tissue from the exposed area.

    • Unlike LASIK, there is no flap created in PRK. Instead, the epithelium naturally regenerates over a few days after the procedure.

    • PRK may have a longer initial recovery period compared to LASIK, as the regrowth of the epithelium takes some time.
