Which Is a Surgery Done to Correct Myopia?

Myopia, commonly known as nearsightedness, is a refractive error that affects a significant portion of the population worldwide. It occurs when the eye is unable to focus light accurately, resulting in blurred vision at a distance while objects up close remain clear. Individuals with myopia often rely on corrective lenses, such as glasses or contact lenses, to enhance their vision. However, for those seeking a more permanent solution, surgery can be an excellent option. In this article, we will explore different surgical procedures that are performed to correct myopia and provide answers to frequently asked questions regarding these surgeries.

1. Laser-Assisted in Situ Keratomileusis (LASIK):
LASIK is one of the most popular surgical procedures for correcting myopia. It involves using a laser to reshape the cornea, the clear front surface of the eye, so that light can be more accurately focused onto the retina. The procedure begins with the creation of a thin flap on the cornea, which is then lifted to expose the underlying tissue. The laser is then used to remove a small amount of corneal tissue, reshaping it to correct the refractive error. The flap is then placed back into its original position.

2. Photorefractive Keratectomy (PRK):
PRK is another laser eye surgery that aims to correct myopia. Similar to LASIK, it involves using a laser to reshape the cornea. However, unlike LASIK, no corneal flap is created. Instead, the outer layer of the cornea, called the epithelium, is removed entirely. The laser is then used to reshape the exposed corneal tissue. Over time, the epithelium naturally regenerates, and the cornea heals, resulting in improved vision.

3. Implantable Collamer Lens (ICL):
ICL is a surgical procedure that involves implanting a small, synthetic lens inside the eye to correct myopia. Unlike LASIK and PRK, which reshape the cornea, ICL works by adding an additional lens to the eye’s optical system. This lens is placed behind the iris and in front of the eye’s natural lens. The ICL corrects myopia by focusing light accurately onto the retina, improving vision. The procedure is reversible, and the lens can be removed or replaced if necessary.

4. Refractive Lens Exchange (RLE):
RLE is a surgery primarily used to correct age-related presbyopia, but it can also be an effective solution for myopia in certain cases. During the procedure, the eye’s natural lens is removed and replaced with an artificial intraocular lens (IOL). The IOL corrects the refractive error, providing clear vision at a distance. RLE is a more invasive surgery compared to LASIK, PRK, or ICL, and it is usually recommended for individuals with more severe myopia or those who have age-related vision changes.


Q: How long does it take to recover from myopia surgery?
A: The recovery time varies depending on the type of surgery performed. LASIK and PRK typically have a shorter recovery period, with most patients experiencing improved vision within a few days to a week. However, it can take several weeks for the vision to stabilize completely. ICL and RLE may have a longer recovery time, with vision improvement occurring gradually over a few weeks.

Q: Are there any risks or side effects associated with myopia surgery?
A: As with any surgical procedure, there are risks involved. Common side effects include dry eyes, glare, halos around lights, and temporary fluctuations in vision. However, these side effects are usually temporary and resolve over time. Serious complications are rare but can include infection, corneal scarring, or vision loss. It is essential to discuss these risks with your ophthalmologist before undergoing surgery.

Q: Is myopia surgery suitable for everyone with nearsightedness?
A: Not everyone with myopia is a suitable candidate for surgery. Factors such as age, stable prescription, overall eye health, and corneal thickness play a role in determining eligibility. It is crucial to undergo a comprehensive eye examination and consult with a qualified ophthalmologist to determine the best course of action.

In conclusion, myopia surgery offers a viable option for individuals seeking a permanent solution to their nearsightedness. LASIK, PRK, ICL, and RLE are all effective procedures that can correct myopia and significantly improve vision. However, it is essential to thoroughly research and consult with an eye care professional to determine the most suitable surgery for your specific needs.
