What Surgical Procedure Is Used to Correct Myopia?

Myopia, commonly known as nearsightedness, is a refractive error that affects a significant portion of the population. It results in blurred vision when looking at distant objects, while close objects remain clear. While eyeglasses and contact lenses have long been a standard solution for correcting myopia, advancements in technology have made it possible to correct this condition through various surgical procedures. In this article, we will explore the most common surgical procedures used to correct myopia, their benefits, risks, and frequently asked questions.

1. LASIK (Laser-Assisted In Situ Keratomileusis):
LASIK is one of the most popular and widely performed surgical procedures for correcting myopia. During the procedure, a thin flap is created on the cornea, which is then lifted to expose the underlying tissue. An excimer laser is then used to reshape the cornea, correcting the refractive error. The flap is then repositioned, and it adheres naturally without the need for stitches. LASIK offers rapid recovery, minimal discomfort, and excellent visual outcomes. However, it may not be suitable for individuals with thin corneas or certain corneal irregularities.

2. PRK (Photorefractive Keratectomy):
Similar to LASIK, PRK also uses an excimer laser to reshape the cornea. However, instead of creating a corneal flap, the surgeon removes the thin outer layer of the cornea, called the epithelium. This allows direct access to the corneal tissue, which is then reshaped using the laser. PRK is an effective procedure for correcting myopia, especially for those with thin corneas or who may not be suitable candidates for LASIK. It does, however, require a longer recovery time compared to LASIK as the epithelium needs to regenerate.

3. SMILE (Small Incision Lenticule Extraction):
SMILE is a relatively newer surgical procedure used to correct myopia. It involves creating a small incision on the cornea and using a femtosecond laser to shape a small disc of tissue, called a lenticule, within the cornea. This lenticule is then removed through the incision, effectively changing the shape of the cornea and correcting myopia. SMILE offers the advantage of a smaller incision, potentially reducing the risk of dry eye and other complications associated with LASIK or PRK. It also provides a quick recovery and has shown promising results in terms of visual outcomes.


Q: Am I a suitable candidate for myopia correction surgery?
A: The suitability for myopia correction surgery depends on various factors, including the stability of your prescription, the thickness of your cornea, your overall eye health, and any underlying medical conditions. It is best to consult with an experienced ophthalmologist who can evaluate your specific case and recommend the most appropriate procedure for you.

Q: How long does the procedure take?
A: The duration of the surgical procedure depends on the technique used and the complexity of your prescription. In general, LASIK and SMILE procedures typically take around 10-15 minutes per eye, while PRK may take slightly longer.

Q: How long is the recovery period?
A: The recovery period varies between procedures. LASIK and SMILE generally offer a quicker recovery, with most patients experiencing improved vision within a day or two. PRK, on the other hand, may require a longer recovery period of several days to a week, as the epithelium needs time to regenerate.

Q: Are there any risks or complications associated with these procedures?
A: While myopia correction surgeries are generally safe and effective, there are potential risks and complications, as with any surgical procedure. These may include dry eyes, glare, halos, infection, corneal haze, or undercorrection/overcorrection. It is crucial to discuss these risks with your surgeon and ensure you understand the potential outcomes before proceeding with the surgery.

In conclusion, myopia correction surgeries have revolutionized the way we treat nearsightedness. LASIK, PRK, and SMILE are the most common surgical procedures used to correct myopia, each offering its own set of advantages and considerations. However, it is important to consult with a qualified eye surgeon to determine the most suitable procedure for your specific needs and to weigh the potential risks and benefits. With the advancements in technology and the expertise of surgeons, these surgical procedures offer hope for those seeking a life free from the dependency on glasses or contact lenses.
