Discover Clear Vision with SMILE Eye Surgery: Your Path to Enhanced Visual Clarity

Do you observe vision difficulties due to astigmatism or myopia (near-sightedness)? If yes, it’s time that you go to a reputed hospital for treatment. Many treatment options are available to help you relieve these eye problems, like laser techniques. To treat this problem, there are advanced methods like Small Incision Lenticule Extraction or SMILE treatment for eyes. Let us know a little more about this procedure.

What is SMILE Eye Surgery?

The clarity of your vision depends on the cornea and lens working together to focus a clear image onto the retina. This process involves the refraction or bending of light rays to create a sharp image on the retina. However, when the cornea’s shape is altered, the image on the retina becomes unfocused, resulting in blurry vision.

SMILE surgery, a cutting-edge procedure, targets these refractive errors by precisely reshaping the cornea. With the help of femtosecond laser, this reshaping process helps to correct the refractive error and improve vision clarity.


When Should You Go for SMILE Eye Surgery?

To undergo eye SMILE surgery, there are specific eligibility requirements mentioned below: 

  • You must be at least at or above the age of 18
  • There should be no change in your eye care prescriptions in 6 months 
  • Near-sightedness prescription should fall between –1 and –10, while astigmatism shouldn’t exceed three diopters. 
  • You must have healthy eyes. 

If you have glaucoma, keratoconus, imbalanced glucose levels, or have any eye allergies, we recommend you avoid choosing Relex SMILE eye surgery to prevent its side effects. 

It is not advisable to go for SMILE surgery during Pregnancy and lactation period and it can be planned after that period.


SMILE Procedure for Eye Correction

SMILE is a form of laser eye surgery performed to bring the cornea of your eyes to its appropriate shape so as to get a clear focus of image on the retina. SMILE surgery is a minimally invasive technique in which our doctors provide an anaesthetic drops to numb the eyes. 

In the SMILE eye procedure, our professionals use a femto laser to create a tiny incision of less than 4mm in the cornea. They use this incision area to take out a small part of corneal tissue called a lenticule. With this technique, your eye surgeon alters the shape of the cornea, improving your vision. After the SMILE which is a sutureless procedure ; your eyes heal faster to allow return to working in 2 to 3 days 

This treatment for eye correction is painless and comfortable as the ZEISS VisuMax femtosecond laser has less suction applied on your eyes. However, other laser procedures create flaps and use more suction force for the same. 


Are Lasik and SMILE Eye Surgery the Same?

Eye SMILE procedure and Laser-assisted In Situ Keratomileusis (LASIK) are both laser surgery options for your eye power correction. Both outcomes are similar as they both work to correct refractive errors by correcting the shape of the cornea. However, SMILE operation for eyes is an advanced form of refractive  surgery and differs in terms of the process of corneal adjustment. 

Moreover, the patients after SMILE surgery recover faster than LASIK surgery. 


Benefits of the SMILE procedure over LASIK

  • In Relex SMILE eye surgery,  tendency to have dry eye is comparatively lesser than in  LASIK surgery. 
  • If you have a high prescription, Relex SMILE treatment is considered more safer than LASIK. 
  • In LASIK surgery corneal flap exists  Relex SMILE has no  flap made in the cornea and hence no flap related complications and safer and heals quicker.
  • If you undergo eye SMILE surgery, there are only fewer chances of tissue and nerve damage.
  • SMILE Surgery laser application time is  quicker than in LASIK, and is done in 20-30 seconds per eye in SMILE.


SMILE Treatment for Different Eye Problems

The advanced SMILE eye surgery procedure is effective in treating different eye problems, which include:  

  • Astigmatism

In this eye disorder, the curvature of your cornea distorts, taking an oval or egg shape and affecting your vision. Astigmatism is of two types – horizontal astigmatism (when the eye gets wider) and vertical astigmatism (when the eye length increases). Resultantly, you have a blurry vision. 

  • Myopia

Myopia is an eye problem in which you can see nearby objects clearly while experiencing blurriness in your distant vision. You may even squint your eyes to try to see things clearly. 

The eye care professionals use 2 mm keyhole incisions for the SMILE procedure. SMILE surgery for myopia and astigmatism eye disorders shows significant results.

After Relex SMILE eye surgery, there may be possible risks or chances of complications. Our eye care professionals perform Relex SMILE treatment with proper safety and necessary precautions. However, the SMILE procedure may involve the following issues:
