Is LASIK safe for all? What you should know before choosing this surgery

LASIK is a popular laser surgery for correcting vision issues. However, one must consider possible side effects and ensure they are suitable for the procedure.

LASIK, or Laser-Assisted In Situ Keratomileusis, is a well-known surgery used to correct common vision problems like nearsightedness, far-sightedness, and astigmatism.

Many people opt for this procedure to reduce or even eliminate the need for glasses or contact lenses. But before choosing LASIK, it's important to understand its safety, potential risks, and whether it's the right option for you.

HOW SAFE IS LASIK?

LASIK is generally considered a safe and effective procedure with a high success rate. Dr Varun Gogia, Senior Ophthalmologist at Pristyn Care, explained, "LASIK has been approved by the FDA and is performed by highly trained specialists. The surgery itself is quick, lasting about 10 minutes per eye, and most people experience significant improvement in their vision within a day or two."

The use of advanced laser technology has made LASIK more accurate and has greatly reduced the chances of complications. "With modern equipment, the risks are minimal," says Dr Gogia. However, like any surgical procedure, LASIK does carry some risks.

POSSIBLE SIDE EFFECTS

While most people are satisfied with their LASIK results, some may experience side effects. Common temporary issues include dry eyes, glare, halos, and sensitivity to light, especially at night. Dr Gogia noted, "These side effects are typically short-term, and in most cases, they resolve on their own within a few weeks."

In rare cases, more serious complications can occur. These might include infections, issues with the corneal flap (the thin layer of tissue created during surgery), or under-correction, where the vision improvement is less than expected.

"It's important to remember that LASIK doesn't guarantee perfect 20/20 vision for everyone," said Dr Gogia. "Some people may still need glasses or contacts for specific tasks, like reading or driving at night."

WHO SHOULD AVOID LASIK?

Not everyone is a good candidate for LASIK surgery. People with unstable vision prescriptions, thin corneas, or conditions like chronic dry eyes or autoimmune diseases may not be suitable for the procedure. "A thorough eye exam is essential to determine if LASIK is right for you," says Dr. Gogia. "Your eye surgeon will assess your overall eye health and recommend whether it's safe to proceed."

In some cases, those with certain medical conditions or who are pregnant or breastfeeding may also need to postpone or avoid LASIK altogether.

As people age, they may still require glasses for activities like reading due to natural changes in their vision. "LASIK doesn’t stop the natural ageing process of the eyes, and some patients may need reading glasses later in life," explained Dr Gogia.

The effects of LASIK are permanent but not reversible. If any complications arise or if vision changes after surgery, further treatment options may be limited.
