ReLEX Smile, an acronym for Refractive Lenticule Extraction, represents a pioneering advancement in the field of laser eye surgery. Developed by the global ophthalmic company ZEISS, ReLEX Smile was introduced as a groundbreaking alternative to traditional LASIK procedures. The history of ReLEX Smile dates back to its approval by the European Conformity (CE) in 2011 and subsequent clearance by the U.S. Food and Drug Administration (FDA) in 2016. This innovative technique diverges from conventional laser surgeries by relying on a minimally invasive approach. Unlike LASIK, ReLEX Smile eliminates the need for creating a corneal flap, making the procedure even gentler and reducing the risk of complications. Over the years, ReLEX Smile has gained popularity for its swift recovery times, enhanced patient comfort, and consistently remarkable outcomes, establishing itself as a transformative chapter in the evolution of vision correction technology.

Can ReLEX Smile Eye Surgery Fix Poor Eye Sight?

Yes, ReLEX Smile eye surgery is designed to address refractive errors and can be effective in correcting poor eyesight. Refractive errors, such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, result from an improper bending of light as it enters the eye, leading to blurred vision. ReLEX Smile utilises a laser to reshape the cornea, the transparent front part of the eye, to correct these refractive errors.

ReLEX Smile is particularly well-suited for treating myopia, and it can also address astigmatism and, in some cases, hyperopia. The procedure involves creating a small lenticule within the cornea using femtosecond laser technology, which is then extracted to reshape the cornea and improve the focusing power of the eye.

However, the suitability of ReLEX Smile for a particular individual depends on various factors, and it is important for anyone considering the procedure to undergo a thorough eye examination and consultation with an experienced eye surgeon to determine the most appropriate treatment for their specific needs.

When Is ReLEX Smile Not Suitable For Eye Surgery? 

While ReLEX Smile is a highly effective and safe procedure for many individuals with refractive errors, there are certain situations where it may not be the most suitable option. Here are some factors that might make ReLEX Smile not suitable for eye surgery:

Severe Refractive Errors

In cases of extremely high or severe refractive errors, other surgical options may be more appropriate. ReLEX Smile has its limits in terms of the range of refractive errors it can effectively correct.

Corneal Thickness

The procedure involves creating a small lenticule within the cornea, and the thickness of the cornea is a critical factor. If the cornea is too thin, ReLEX Smile may not be suitable, as it requires a certain amount of corneal tissue for the creation and extraction of the lenticule.

Irregular Corneal Shape

Individuals with irregular corneal shapes, such as those with keratoconus, may not be ideal candidates for ReLEX Smile. Other procedures may be more appropriate in such cases.

Previous Eye Surgery

If a person has had previous eye surgery, particularly laser surgery, ReLEX Smile may not be recommended due to changes in the corneal structure.

Pregnancy and Nursing

Hormonal changes during pregnancy and nursing can affect vision stability. It is generally recommended to wait until hormonal levels stabilise before undergoing any elective eye surgery.

Eye Diseases or Conditions

Certain eye diseases or conditions, such as glaucoma or severe dry eye, may disqualify individuals from ReLEX Smile. Pre-existing eye health issues should be thoroughly evaluated before considering the surgery.


While there is no strict age limit, the stability of a person's vision is crucial. Younger individuals, whose vision is still changing, may be advised to wait until their prescription has stabilised before considering ReLEX Smile.

Moreover, individuals considering any eye surgery, including ReLEX Smile, undergo a comprehensive eye examination and consultation with an experienced eye surgeon. The surgeon will assess various factors to determine the most suitable procedure for the individual's unique circumstances and needs.

What Is The Technology Behind ReLEX Smile?

The technology behind ReLEX Smile involves the use of femtosecond laser technology to reshape the cornea.

Here's a breakdown of the key steps in the ReLEX Smile procedure:

Femtosecond Laser

The procedure begins with the use of a femtosecond laser, which emits ultra-short pulses of laser light. This laser is highly precise, allowing surgeons to create extremely small and accurate incisions in the cornea.

Creation of Lenticule

The femtosecond laser is used to create a small, disc-shaped lenticule within the cornea. The lenticule contains the tissue that needs to be removed or altered to correct the refractive error. ReLEX Smile does not involve creating a corneal flap; instead, a small incision is made to access the lenticule.

Lenticule Extraction

After the lenticule is created, the surgeon carefully removes it through the small incision. This process changes the shape of the cornea, correcting the refractive error and improving the eye's ability to focus light properly onto the retina.

Corneal Reshaping

The removal of the lenticule changes the curvature of the cornea, allowing light to be focused more accurately onto the retina, which improves vision.

Furthermore, the success of the ReLEX Smile procedure depends on precise planning, accurate laser technology, and the expertise of the surgeon. Before undergoing ReLEX Smile or any other laser eye surgery, individuals should have a thorough consultation with an eye care professional to determine their suitability for the procedure.

Relex Smile Vs LASIK

ReLEX Smile and LASIK are both advanced laser eye surgery techniques designed to correct refractive errors and reduce or eliminate the need for glasses or contact lenses. While they share the goal of improving vision, there are notable differences in their approaches and procedures.

ReLEX Smile, or Refractive Lenticule Extraction, is a newer and minimally invasive procedure compared to traditional LASIK. One key distinction is the absence of a corneal flap in ReLEX Smile. Instead, a small, disc-shaped lenticule is created within the cornea using a femtosecond laser. This lenticule is then extracted through a small incision, reshaping the cornea and correcting the refractive error. The lack of a flap is believed to contribute to a quicker recovery and potentially less disruption to corneal nerves.

LASIK, or Laser-Assisted In Situ Keratomileusis, involves creating a corneal flap with a microkeratome or femtosecond laser. The flap is lifted, and an excimer laser is used to reshape the cornea before the flap is repositioned. LASIK has been a widely practised and successful procedure for many years, with a proven track record of safety and effectiveness. The creation of a corneal flap allows for rapid visual recovery, and the procedure is known for its ability to provide quick results.

In terms of candidacy, ReLEX Smile may be preferred for individuals with thinner corneas or those engaged in contact sports due to its minimally invasive nature. LASIK, on the other hand, maybe more suitable for those with certain corneal irregularities or those seeking a well-established procedure. Ultimately, the choice between ReLEX Smile and LASIK depends on individual factors and thorough consultation with an experienced eye surgeon is crucial in determining the most suitable option for each patient.
