I Have Nearsightedness. Should I Go For A Smile Lasik Eye Surgery?

I Have Nearsightedness. Should I Go For A Smile Lasik Eye Surgery?

Condition in which a person can see nearby objects clearly but far objects appear blurry is known as Near-sightedness. It is also known as Myopia.The rays refracted by the eye should be focused on the retina to see the image. In this disorder, the eye focuses the rays incorrectly in the front of the retina instead of on the retina. There are no natural remedies to treat near-sightedness. An eye doctor can diagnose near-sightedness and will suggest corrective measures during consultation.There are various techniques to use by an eye specialist to treat near-sightedness. One such effective technique is SMILE.

Know About Smile Lasik Eye Surgery

SMILE, also known as “Small incision lenticule extraction”, is the refractive eye process. It is an efficient and popular technique to treat refractive error.It is currently mainly used in treating near-sightedness. It is a quicker process with a high success rate.

It makes vision correction possible in people who were not suitable candidates for vision correction surgery. It is almost the same as LASIK. The only difference is a small incision on the cornea is created to reshape it instead of the corneal flap.

How Will My Doctor Perform Smile Lasik Eye Surgery?

SMILE is performed by an experienced eye specialist or eye surgeon only. Firstly, to ensure a painless process, the surgeon will administer the an aesthetic eye drops in the eye. It is to numb the eyes. Then the eyelids forceps are placed on the eyes to prevent it from blinking.

After this, using the femtosecond laser, a tiny lens-shaped bit of tissue (called lenticular) is created by the eye surgeon within the cornea.Using the same laser, the surgeon makes a small arc-shaped incision on the cornea. Then the eye surgeon removes the lenticule through the incision made. It is later discarded. Once the lenticule is removed, it alters the shape of the cornea and focuses the light correctly on the retina.

The corneal incision heals automatically after some week without any stitches on the cornea. After the completion of surgery, the doctor will prescribe you the eye drops to administer and will give you instructions to be followed and will call back after a day to check for regular check-ups

Initially, SMILE took around 2 minutes per eye to perform. Currently, it takes about 24 seconds to complete the process. With high-quality cuts, the process will come down to 10 seconds in the coming future. It can correct a high degree of near-sightedness.

Am I A Suitable Candidate For Smile Lasik Eye Surgery?

For undergoing a SMILE eye surgery, you should be

  • Above 22 years of age
  • Should have stable vision (no change in prescription in over a 3 months)
  • It can be used to treat near-sightedness in the range of 1-10 dioptres and astigmatism up to 3 dioptres
  • Should not be pregnant and nursing
  • Should not be suffering from autoimmune diseases such as HIV, AIDS, Rheumatoid arthritis
  • Should not have diseases like Diabetes, Hypertension as it delays post healing
  • Should have a healthy cornea, free from scarring or infection

How Smile Lasik Eye Surgery Advantageous Over Lasik Eye Surgery?

  • SMILE is a more demanding process largely dependent on the surgeon’s surgical skills and laser handing technique. SMILE involves better patients’ comfort and represents the beginning of the new era in Ophthalmology.
  • LASIK surgery involves creating a small flap on the surface of the cornea. However, no such flap is created in SMILE. That’s the reason SMILE is also known as “Flapless laser eye surgery”.
  • SMILE is safer and more stable than LASIK. In addition, it preserves Corneal Biomechanics (the anterior part of cornea which is strongest), which is not the case in LASIK.
  • Earlier rehabilitation with SMILE. People operated with Lasik can go for activities like swimming, sports, rubbing eyes within a few days. However, these activities can only be performed for about a month in the case of LASIK.
  • The risk of corneal ectasia is reduced in SMILE in comparison to LASIK. On the other hand, corneal ectasia is a significant disadvantage of LASIK.
  • LASIK treated eyes get weaker as it involves the creation of the corneal flap. It does not happen with SMILE.

SMILE is mainly used in treating near-sightedness and astigmatism. While still in its early stages, SMILE has shown an excellent success rate. The success rate of SMILE primarily depends on the less recovery time, no flap complications, improved vision, improved corneal bio mechanics, and faster recovery from post-operative dry eyes, infection, and quicker rehabilitation.
