SMILE Series (Femtosecond Small Incision Lenticule Extraction)
Overview
SMILE stands for Small Incision Lenticule Extraction, widely known as the "smile laser surgery". It is an all-femtosecond laser corneal refractive procedure with no corneal flap, recognized for minimal trauma and superior corneal integrity. At Aier Yingzhi, we provide two mature SMILE solutions: SMILE Pro (new generation premium) and classic SMILE 3.0.
How It Works
A femtosecond laser precisely sculpts a tiny refractive lenticule inside the corneal stroma. A micro 2–4mm curved incision is created to extract the lenticule, reshaping corneal curvature to correct myopia and astigmatism. No excimer laser or corneal flap is required throughout the process.
SMILE Pro (Premium Version)
Equipped with Zeiss VisuMax 800 ultra-high-speed laser platform for faster scanning and sub-micron positioning accuracy
Ultra-small 2–4mm arc incision, fully preserving corneal biomechanical stability
Significantly reduced post-op dry eye symptoms and stronger impact resistance
Correction range: Myopia 50–1000 degrees, Astigmatism ≤500 degrees
Ideal candidates: Athletes, military staff, outdoor workers, frequent travellers and anyone prone to dry eyes
Classic SMILE 3.0
Mature, proven standard SMILE technology with stable clinical outcomes
Fast visual recovery; most patients resume work and study the next day
Cost-effective minimally invasive all-laser option for mild-to-moderate myopia
Key Advantages
Flap-free design eliminates flap-related complications
