Eye health is one of the most sensitive aspects of quality of life. Today, many people choose laser eye surgery to free themselves from dependence on glasses or contact lenses. One of the most advanced methods in this field is SMILE Laser.
SMILE Laser (Small Incision Lenticule Extraction) is a minimally invasive laser technique applied to the cornea. It stands out with its high success rate, short recovery period and long-lasting results. However, some patients wonder, especially years after surgery or when their prescription changes:
In this article, we will explain in detail based on the clinical experience of Op. Dr. Diclehan whether SMILE Laser can be repeated, under what conditions this decision is made, and what alternative treatment options are available.
The Most Advanced Level of Modern Laser Technology
SMILE Laser represents the latest stage of femtosecond laser technology. Unlike traditional techniques, no large flap is created on the cornea. Instead, a tiny lenticule (a thin corneal tissue segment) is formed within the cornea and removed through a micro-tunnel. This permanently corrects the refractive error.
Op. Dr. Diclehan describes SMILE Laser as:“A laser treatment that provides maximum visual correction with the least amount of tissue intervention.”
SMILE Laser is generally performed to treat myopia and astigmatism in patients over 18 whose corneal structure is suitable.
In some patients, minor prescription changes may occur years after laser surgery. This usually results from the eye’s natural biological changes rather than treatment failure.
According to Op. Dr. Diclehan“SMILE Laser offers permanent correction. However, small prescription shifts can occur over time due to age, hormonal or environmental changes. In such cases, an additional corrective procedure may be needed.”
This leads many patients to ask
In Theory Yes But Only Under the Right Conditions
SMILE Laser can be repeated, but not in every patient. The decision depends on corneal thickness, current eye health, the degree of refractive change and the effect of the first surgery.
As Op. Dr. Diclehan states:“A second SMILE procedure is possible, but only if the eye structure allows it. Corneal thickness, the level of residual refractive error and surface health must be evaluated very carefully.”
So, a repeat procedure can only be planned after a detailed pre-operative assessment.
Doctors evaluate several factors
Enough corneal tissue must remain after the first surgery. If insufficient, a second SMILE procedure will not be performed.
There must be no thinning (ectasia), irregularity or surface damage.
Very mild refractive changes may not justify surgery.
Tear function must be stable.
Conditions such as glaucoma, keratoconus or retinal damage rule out surgery.
Sometimes a second SMILE procedure (Re-SMILE) is not technically suitable. Other options include:
• PRK (Surface Ablation)
• LASIK enhancement
• ICL (Implantable Contact Lens) — especially for high prescriptions
The eye must first fully stabilize usually after at least 6–12 months.
As with any surgery, there are risks but with proper patient selection they are minimal, such as:
• Rare corneal thinning
• Temporary visual fluctuations
• Mild dryness
• Slightly longer recovery
According to Op. Dr. Diclehan:“Second laser surgeries require experience. With careful planning and correct indication, the risk is very low.”
First, the cause must be identified. Sometimes the change is temporary and stabilizes without surgery. Treatment is only considered after stability is confirmed.
• Continue with the same surgeon if possible
• Protect eye health and manage screen time
• Attend routine eye examinations
• Stop contact lens use before evaluation
A new lenticule is formed inside the cornea and removed requiring high surgical precision and expertise.
Studies show that with correct patient selection repeat procedures achieve success rates of over 95%.
Artificial-intelligence-assisted laser platforms now improve precision and safety even in enhancement surgeries.
Wearing sunglasses, limiting UV exposure, reducing screen strain, using lubricating drops and attending annual exams are essential.
According to Op. Dr. Diclehan“A well-performed SMILE procedure provides lifelong clarity as long as the patient protects their eye health.”
SMILE Laser is a revolutionary procedure and repeat surgery is possible when necessary, provided the eye structure is suitable and the operation is planned by an experienced surgeon.
