Femtosecond Laser (Intralase)
Femtosecond laser (Intralase) is a technology that creates micron-level precise incisions using pulses as short as one quadrillionth of a second. It is used in laser eye surgeries, SMILE, cataract surgery, and adjunctive procedures in keratoconus.

Quick Answer
Femtosecond laser (Intralase) creates micron-level, blade-free, and predictable incisions in the cornea using ultra-short pulses. It is used to create the corneal flap in iLASIK, and for precise incision/channel stages in cataract and keratoconus surgery.
What Is Femtosecond Laser (Intralase)?
Femtosecond laser is a technology named after the duration of the laser pulse. A femtosecond represents a time interval as short as one quadrillionth of a second.
Use in Eye Treatments
Femtosecond laser technology plays an adjunctive role in various eye surgeries:
- Laser eye surgeries (myopia, hyperopia, astigmatism)
- SMILE laser treatment
- Certain stages of cataract surgery
- Corneal surgeries
- Adjunctive procedures in keratoconus treatment (corneal ring placement, corneal transplantation)
Key Advantages
The technology allows micron-level precise incisions to be created, making surgical procedures more predictable. It operates with computer-controlled systems and enables personalized planning.
Suitability
Which patients it can be applied to depends on factors such as corneal thickness, refractive error, and ocular surface health. A detailed eye examination is required.

iLASIK Laser Eye Surgery
iLASIK is a modern method that uses two laser technologies together to correct myopia, hyperopia, and astigmatism: a femtosecond laser creates a thin corneal flap, after which an excimer laser reshapes the cornea.

Laser Refractive Surgery
Laser refractive surgery is a surgical treatment method based on reshaping the cornea with a laser to correct vision disorders such as myopia, hyperopia, and astigmatism. LASIK, iLASIK, PRK, and SMILE techniques are applied following a personalized evaluation.

SMILE Laser Eye Surgery
SMILE (Small Incision Lenticule Extraction) is a modern, flapless laser eye surgery based on removing a thin piece of tissue (lenticule) created inside the cornea through a small incision, in order to correct myopia and astigmatism.
