Uncover the Myths about LASIK

Uncover the Myths about LASIK

Despite a nearly 30 years’ history of LASIK or Refractive Surgery, there are still some myths among those who are concerned about the procedure. Let’s discuss the common myths that we usually encounter nowadays.


Myth #1: LASIK or Refractive Surgery is painful.

Truth: Generally, there will not be any pain sensation on the eye during the Refractive Surgery procedure. The reason being is your eye doctor will instill anaesthetic eye drops to numb your eye. The anaesthetic effect will usually last until the whole procedure has been completed. Therefore, you will feel no pain even after you step out the operation theatre. However, there might be mild grittiness or stinging sensation which will usually last for the first few hours after the procedure. With the World’s most advanced Refractive Surgery – Small Lenticule Extraction (ReLEx Smile), it greatly reduces the mild grittiness that may occur after the procedure.

Myth #2: LASIK or Refractive Surgery may cause blindness.

Truth: Although nowadays Refractive Surgery is performed under high levels of safety, it is still considered as a surgery whereby certain risks may be involved. However, the number of blind cases due to Refractive Surgery is still ZERO in Singapore. Therefore, a thorough eye examination followed by doctor’s consultation are important to review all benefits and risks of Refractive Surgery before making decision.

Myth #3: I will not need any eyeglasses after LASIK or Refractive Surgery

Truth: Our vision may change with time regardless of any Refractive Surgery. Hence, even if one have had Refractive Surgery, he or she may still need eyeglasses at certain phase of life after the procedure. For instance, all of us will start to have reading difficulty when we reach the age of 40 to 50s due to the loss of crystalline lens elasticity – Presbyopia. Eyeglasses with near reading prescription can easily overcome this issue.

Myth #4: Laser may burn your eyes.

Truth: A “cold” laser named Excimer is used in certain Refractive Surgery. “Cold” laser means that it does not burn the corneal cells, in fact, it disrupts the molecular bond that holds together the corneal cells. However, some patients may report burning smell during the procedure. The odour is from the chemical reaction of the laser on the cornea. Some refractive surgery machines have a build-in vacuum device to remove the odour.


Myth #5: There are permanent side effects from LASIK or Refractive Surgery.

Truth: Laser surgery is still considered a surgery, and with every surgery there are risks involved. One common side effect after LASIK is dry eyes, and they usually lessen with time. However, in a small number of patients, it may be permanent. This can be overcome by the use of lubricating eyedrops.
