SMILE Laser Eye Surgery: A Next-Generation Laser Method

Using glasses or contact lenses may become a routine over time, yet it can also create practical challenges in daily life—fogged lenses on rainy days, dryness from long-term contact lens use, or limitations for individuals with an active lifestyle.

What if clear vision were possible upon waking and could be maintained throughout the day? One of the latest advancements in laser eye treatments, the ReLEx SMILE method, has emerged as a technology that addresses this possibility.

SMILE Laser—also known as ReLEx SMILE—is a minimally invasive laser procedure performed without creating large corneal incisions. This approach is considered a comfortable option for many individuals seeking to reduce dependence on glasses or contact lenses. Its ability to be evaluated even in cases with more sensitive corneal structures has positioned it as a distinct option among modern laser treatments.

This article provides a comprehensive overview of what ReLEx SMILE is, how it is performed, general eligibility considerations, and the comfort it offers.

What Is SMILE Laser Eye Surgery?

SMILE Laser Eye Surgery is an advanced laser technology used in the management of refractive errors such as myopia and astigmatism. Known in medical literature as ReLEx SMILE, this technique is performed through a minimal incision and does not require creating a large corneal flap. By preserving the natural structure of the cornea, the recovery process may be more comfortable.

Compared with other laser methods, SMILE Laser involves less tissue disruption, which may help reduce postoperative complaints such as dry eye sensations. The procedure is planned on an individual basis, with the aim of providing a safe and controlled experience.

As an alternative to glasses or contact lenses, SMILE Laser is regarded as one of the most advanced applications in laser vision correction. Its relatively quick return to daily activities and overall comfort have contributed to its growing consideration among modern treatment options.

Who May Be Considered for SMILE Laser Eye Surgery?

SMILE Laser Eye Surgery may be evaluated for individuals with refractive errors such as myopia and astigmatism. Because it is performed with a minimal incision, it may also be considered in cases where corneal structure is relatively thin, with the goal of preserving corneal integrity.

General eligibility is determined after a detailed eye examination. Commonly discussed criteria include:

• Overall health status suitable for a surgical procedure
• Being 18 years of age or older
• Stable refractive values for at least one year
• Myopia up to approximately −10.00 diopters and astigmatism up to −5.00 diopters
• Adequate corneal thickness and structure
• Absence of certain significant eye conditions such as cataract, glaucoma, or keratoconus

Who May Not Be Considered Suitable for SMILE Laser Eye Surgery?

SMILE Laser Eye Surgery may not be appropriate in every case. Determining suitability requires a comprehensive eye examination. In general, the method may not be evaluated for individuals who:

• Are under 18 years of age
• Have refractive values that are still changing
• Have insufficient corneal thickness or structural limitations
• Have significant ocular conditions (such as cataract, glaucoma, or keratoconus)
• Are pregnant or breastfeeding
• Have active eye infections
• Have autoimmune or systemic conditions that may affect wound healing

For such cases, alternative treatment approaches may be discussed. Consultation with an eye care specialist is recommended to determine the most appropriate option.

How Is SMILE Laser Eye Surgery Performed?

SMILE Laser Eye Surgery is typically completed in a short time frame and is designed to be a comfortable procedure. The ReLEx SMILE process generally involves three main steps:

Eye Preparation and Anesthesia

Before the procedure, the eye surface is sterilized and topical (drop-based) local anesthesia is applied. This helps ensure comfort during the procedure. The individual remains awake, and pain is not expected.

Creation of the Lenticule

Using a VisuMax femtosecond laser system, a small disc-shaped piece of tissue (lenticule) is created within the middle layer of the cornea to correct the refractive error. This step usually takes about 10 seconds per eye and minimizes interaction with surrounding tissue.

Removal of the Lenticule

A small incision, approximately 2–4 mm in length, is created at the corneal edge. Through this opening, the surgeon carefully removes the lenticule. No sutures are required, as the incision heals naturally.

The entire procedure for both eyes is usually completed within 8–10 minutes. Recovery time may vary, but many individuals resume daily activities relatively quickly.

Advantages of SMILE Laser Eye Surgery

SMILE Laser Eye Surgery is considered a next-generation laser method offering several potential advantages related to comfort and recovery.

Minimal Intervention, Enhanced Comfort

The procedure is performed through a small incision, which helps preserve corneal structure and may contribute to a more comfortable postoperative experience.

Reduced Dry Eye Complaints

Because many corneal surface nerves remain intact, sensations of dryness reported with some traditional laser methods may be less frequent.

Faster Return to Daily Activities

Most individuals are able to return to routine activities shortly after the procedure, with temporary sensitivity or blurred vision typically resolving over time.

Single-Step Laser Application

The procedure is completed using a single laser system in one continuous process, helping streamline the treatment experience.

Flap-Free and Suture-Free Technique

Since no corneal flap is created, flap-related concerns are avoided. This feature may be particularly appealing for individuals involved in physically active lifestyles.

Recovery After SMILE Laser Eye Surgery

Recovery following SMILE Laser Eye Surgery is often described as comfortable and relatively rapid. In the first few hours, mild stinging, tearing, or light sensitivity may occur but generally decreases quickly.

First 24 Hours

Use of protective eyewear and avoiding eye rubbing are recommended. Contact with water should be avoided during this period.

First Days

Regular use of prescribed antibiotic and lubricating eye drops supports healing and helps reduce infection risk.

First Week

Many individuals return to daily activities the day after treatment. However, avoiding eye makeup, swimming, and dusty environments during this period is generally advised.

Recovery experiences may vary, so following professional guidance is important for a smooth process.

Information About SMILE Laser Pricing

The cost of SMILE Laser Eye Surgery may vary depending on ocular structure, individual needs, and the technology used.

For detailed information and personalized evaluation, contact with the clinic may be made following a comprehensive eye examination. Treatment planning is determined after professional assessment.

SMILE Laser and ReLEx SMILE technologies represent modern laser methods applied with minimal intervention. By preserving corneal structure, these approaches aim to support correction of refractive errors such as myopia and astigmatism. SMILE Laser Eye Surgery may help reduce dependence on glasses or contact lenses and support greater comfort in daily life.

Eligibility and outcomes depend on individual ocular characteristics. When planned for appropriate candidates, this method may support long-term visual improvement.
