Which Is a Surgery Done to Correct Myopia

Myopia, commonly known as nearsightedness, is a refractive error that affects millions of people worldwide. It is characterized by a difficulty in seeing objects that are far away while objects up close appear clear. While eyeglasses and contact lenses are popular solutions to correct myopia, many individuals seek a more permanent solution. In recent years, various surgical procedures have gained popularity in correcting myopia. This article will explore the different surgical options available and provide answers to frequently asked questions regarding these procedures.

1. LASIK (Laser-Assisted in Situ Keratomileusis):
LASIK is one of the most common surgical procedures performed to correct myopia. It involves using a laser to reshape the cornea, the clear front surface of the eye. During the procedure, a thin flap is created on the cornea, which is then lifted to allow the laser to reshape the underlying tissue. The flap is then put back in place, without the need for stitches. LASIK is a quick procedure with minimal discomfort, and most patients experience improved vision within a day or two.

2. PRK (Photorefractive Keratectomy):
PRK is another laser-based surgical procedure for myopia. Unlike LASIK, which creates a corneal flap, PRK removes the thin outer layer of the cornea, called the epithelium, before reshaping the underlying corneal tissue. The epithelium regenerates naturally over a few days following the procedure. PRK is suitable for patients with thinner corneas or those who may not be good candidates for LASIK. The recovery time for PRK is longer than LASIK, and it may take several weeks for vision to stabilize.

3. SMILE (Small Incision Lenticule Extraction):
SMILE is a newer refractive surgery technique used to correct myopia. This minimally invasive procedure involves using a femtosecond laser to create a small disc-shaped piece of corneal tissue, called a lenticule, within the cornea. The surgeon then removes the lenticule through a small incision. By removing the lenticule, the shape of the cornea is altered to correct the myopia. SMILE offers faster recovery and reduced risk of dry eye compared to LASIK and PRK.

4. Implantable Collamer Lenses (ICL):
ICL is a surgical option for patients with moderate to high myopia who may not qualify for laser-based procedures. In this procedure, a biocompatible lens made from a collagen-like material is inserted into the eye, behind the iris and in front of the natural lens. The ICL corrects the refractive error to improve vision. Unlike LASIK or PRK, ICL is reversible, and the lens can be removed or replaced if necessary.


Q1. How long does the surgery take?
The duration of the surgery varies depending on the procedure. LASIK and SMILE typically take around 15 minutes per eye, while PRK may take slightly longer.

Q2. Is the surgery painful?
Most patients report little to no pain during the surgery. Local anesthesia is used to numb the eye, and any discomfort experienced afterward can be managed with prescribed medication.

Q3. What are the potential risks and complications?
While complications are rare, they can include dry eyes, glare, halos, infection, and under or overcorrection. It is essential to discuss the potential risks with your surgeon before deciding on a procedure.

Q4. Is everyone eligible for these surgeries?
Not everyone is a candidate for refractive surgery. Factors such as age, eye health, and stability of the prescription must be considered. A comprehensive eye examination by an experienced surgeon will determine eligibility.

Q5. Will I still need glasses or contact lenses after the surgery?
In most cases, refractive surgery significantly reduces the dependence on glasses or contact lenses. However, some individuals may still require low prescription glasses for specific activities, such as reading or driving at night.

In conclusion, several surgical options are available to correct myopia, each with its advantages and considerations. LASIK, PRK, SMILE, and ICL are effective procedures that offer improved vision for individuals seeking a more permanent solution to their refractive error. It is crucial to consult with an experienced eye surgeon to determine the most suitable procedure for your specific case.
