Question 1

Why do people have ReLEx SMILE / LASIK surgery?

Accepted Answer

Research has shown that there are four main reasons that people choose to have LASIK. They are:

Life simplification: No longer having to deal with glasses or contacts.
Independence: Freedom from dependence on glasses and/or contacts.
Performance: Ability to perform better in sports-related activities.
Ability to see 24/7 when it counts: Better vision for all occasions (e.g., during sports activities, swimming, evening out etc.)
LASIK can also increase field of vision which is restricted in spectacle wear.

Question 2

Do I need an examination first?

Accepted Answer

Prior to treatment, you will have a thorough eye examination, called a laser vision consultation, conducted at DLEI to determine whether your eyes are healthy and suitable for LVC (Laser Vision Correction) . In addition, a detailed video and computer image is taken of your eye that will detail the curvature, shape, overall smoothness and regularity of the cornea.

Question 3

How much can Laser Eye Surgery improve my vision?

Accepted Answer

This depends largely on the amount of correction required. Most people require a low to moderate degree of laser vision correction that should result in vision similar to that with glasses or contact lenses. Vision is usually blurry in the first 1-2 hoursafter the LVC procedure. After few hours vision comes back to normal.

Question 4

How long does it take to recover from Laser Eye Surgery?

Accepted Answer

We recommend you plan to have laser vision correction when you can afford 2 days to relax and enjoy the benefits of your new vision. A postoperative visit is required at 24 hours. The healing of the eye occurs during this period so we recommend you take a day or two off from work.

Question 5

Am I a candidate for LASIK?

Accepted Answer

The decision to have laser vision correction depends on the results of a thorough preoperative evaluation. Just as you are a unique individual, each eye requires unique and careful examination with the best technology. At Dada laser eye institute, we complete a 2 hour, evaluation to determine whether or not you are a safe candidate for laser vision correction. Some basic requirements include:

A stable eyeglass prescription for at least 1 year
Best corrected vision of at least 20/40.
Healthy cornea.
No active eye disease.
Over 18 years old.

Question 6

What is ReLEx?

Accepted Answer

It is an acronym standing for- Refractive Lenticule Extraction (ReLEx)is a novel refractive surgery and the most recent, advanced laser vision correction procedure in the world. Many surgeons believe that this No-Flap All-Femto laser vision correction is the safest technique so far

Question 7

What is SMILE?

Accepted Answer

It is an acronym standing for Small Incision Lenticule Extraction ( SMILE ) is a minimally invasive and innovative procedure. Instead of the laser ablation of the cornea, only minimal amount is lasered to create a lenticule which is then extracted through a keyhole corneal incision (compare 2mm to 20 mm used in LASIK) ReLEx and SMILE are same but both terminologies are used commonly worldwide.

Question 8

What are the advantages of ReLEx SMILE?

Accepted Answer

Short recovery time
Less Dry Eye
No flap related complications
Less post operative precautions and care
Inadvertent eye rubbing is safe
Safest procedure so far

Treatment type	Advantages	Limitations
ReLEx SMILE	BLADELESS and FLAPLESS 2 mm incision surgery hence least post operative care Inadvertent eye rubbing is allowed Very fast recovery time Patient having Less corneal thickness can also be treated	Not suitable Plus number (Hyperopia) at present (May 2016)
Bladeless Femto Customvue Lasik	Very precise, bladeless flap hence recovery is fast. Treats astigmatism/ high cylindrical power and plus number (Hyperopia) accurately	Flap precautions are to be taken care like no rubbing till flap is stable.
Customvue Blade Lasik	Gives personalized treatment to eye by treating highest degree of corneal abnormality (abbrations). Very precise as it has IRIS REGISTRATION technology which register your eye and notice even a micro movement hence laser firing is on target area always.	Not recommended when corneal thickness is less Flap precautions are to be taken care like no rubbing till flap is stable.
Photo refractive keratotomy (PRK)	When the shape of cornea is not normal. No flap. Variants – LASEK, Epi-Lasik, ASA	Work resume after 15 days. return of some spectacle number is possible. Eye drops used for longer duration
Implantable Contact Lens (ICL)	When the eye power is extremely high and none of the procedure can be done When thickness of cornea is less Increase quality as well as quantity of vision	More Invasive than Relex Smile or Lasik
