Femtosecond laser surgery uses ultra-short infrared laser pulses to create precise cuts within the eye. It is employed in corneal and cataract procedures to improve accuracy and reproducibility.
Uses in Eye Surgery
In LASIK, the femtosecond laser creates a thin corneal flap instead of a mechanical blade. In cataract surgery, femtosecond lasers can assist with corneal incisions, capsulotomy, and lens fragmentation.
- Energy is focused at a specific depth, forming microscopic bubbles that separate tissue
- Computer guidance allows highly predictable flap thickness and shape
- Reduced mechanical stress may benefit certain corneal shapes
- Not all cases require or benefit from femtosecond assistance
Advantages and Considerations
Femtosecond technology can enhance precision and potentially safety, but overall outcomes also depend on surgical expertise and case selection. Costs are often higher than purely manual approaches.
- Side effects can include transient light sensitivity and interface inflammation
- Patients usually experience similar recovery times to conventional techniques
- Choice of technology is tailored to individual anatomy and surgeon preference
- Both femtosecond and manual methods can achieve excellent results
