Femtosecond laser-assisted cataract surgery, or FLACS, uses a computer-guided laser to perform key steps of cataract surgery. It aims to increase precision and consistency compared with using handheld instruments alone.
How FLACS works
The laser is used before the main lens removal. You lie under a scanning system that maps your eye in detail.
- The laser creates tiny, accurate cuts in the cornea for access
- It forms a centred circular opening in the lens capsule capsulotomy
- The cataract is pre-softened and divided into segments
- The surgeon then completes removal and lens implantation as usual
Potential advantages and considerations
FLACS may offer particular benefits in complex cases, though outcomes are similar to excellent conventional surgery for many people.
- More consistent capsulotomy size and position can help lens stability
- Less ultrasound energy may be needed in some dense cataracts
- Extra equipment and time can increase cost and availability limits
- Your surgeon will advise whether FLACS adds value in your situation
