What is Smile Eye Surgery?

According to our specialist in SMILE Eye Surgery Dr. Shweta Jain through a SMILE eye surgery procedure, the eye specialists first apply eye drops to anesthetize the eye. A speculum is then precisely placed on the lids to keep the eye open and to stop blinking. Using high-level femtosecond technology- the surgeon then builds a precise lenticular which is a thin and circular piece of tissue. The surgeon then separates the lenticular through the tiny incision that was built in the eye. After using the laser, the patient will be permitted to recover for a few minutes before the eye doctor returns and checks the eye. Also, enables the patient to leave.

SMILE Eye Surgery

SMILE Surgery Procedure

SMILE has a minimally invasive and painless procedure. In SMILE technology, only 1 laser known as a femtosecond laser is applied. The laser cuts out a part of tissue i.e Lenticule which is then dragged out by a little opening to produce vision correction.

The surgery takes just 5-10 mins. Below are the steps:

  • Eye specialists first apply eye drops to anesthetize the eye. 
  • A speculum is then precisely placed on the lids to keep the eye open and to stop blinking. 
  • Using high-level femtosecond technology- the surgeon then builds a precise lenticular which is a thin and circular piece of tissue. 
  • The surgeon then separates the lenticular through the tiny incision that was built in the eye. 
  • After using the laser, the patient will be permitted to recover for a few minutes before the eye doctor returns and checks the eye. 

Benefits of Smile Eye Surgery 

SMILE has multiple benefits over the traditional LASIK surgery. People with or without astigmatism can benefit from SMILE eye surgery, which is an excellent alternative to the more well-known LASIK and LASEK procedures.

Suitable for most people

Because SMILE is a minimally invasive form of laser eye surgery, it is suitable for a wider range of people than LASIK and LASEK. For patients who have been told they cannot undergo other forms of surgery, this is a significant benefit for them.

No dry eyes

Due to the absence of a flap to heal, you are significantly less likely to develop dry eyes after SMILE surgery than you would after LASIK surgery

No flap issues

One of the primary differences between SMILE eye surgery and other procedures like LASIK is that the SMILE technique does not create a flap. This eliminates the possibility of issues such as the flap folding or moving, as well as making the eye more comfortable after the treatment.

Quick procedure

SMILE is a short operation, just like other laser eye surgery procedures. The average treatment time is between 20-30 minutes.

Speedy recovery

Due to the lack of a flap around the cornea, patients should expect to recover quickly after SMILE eye surgery and suffer less discomfort than they would with LASIK.

Fast outcomes

Within the first few hours after SMILE eye surgery, eyesight often improves by 80%, with maximum improvement occurring within a few weeks.

FAQ's

SMILE Laser Eye Surgery is named as Small Incision Lenticule Extraction. It is a specs removal surgery, similar to LASIK. SMILE is a type of procedure of refractive surgery that uses a Femtosecond Laser, and performs a bladeless and painless surgery.

Most patients report that they feel a slight sensation of stress on the eye, but even that it is widely omitted by the numbing eye drops while performing Laser eye surgery. And in SMILE, patients typically report feeling completely nothing throughout the entire procedure.

In a SMILE eye surgery, the procedure to be done by the eye specialists normally takes about 10 – 15 minutes.

The surgeon will withdraw the lenticule by a small incision at the front portion of the eye. This reshapes the cornea and corrects the refractive error. SMILE may be a choice for many people with a kind of vision impairment – from mild refractive faults to severe nearsightedness and astigmatism.

SMILE is a quicker procedure, and long-term difficulty risks are much smaller as there is no flap in the cornea, an incision is much less 2–3 mm in a SMILE than 18–20 mm in LASIK. Lasik is viewed as second-generation refractive surgery. SMILE is the third generation.

The latest and advanced SMILE eye surgery procedure is safe and effective in correcting eye problems. This extraction surgery has been done since 2012 and is being officially done in the US since 2016. It is now an FDA-approved procedure.

It can be done above 18 years up to 40 years. However, eligibility has to be determined through a series of tests.
