Both are modern ways to remove a cataract and place a new lens. In both, ultrasound is used to remove the cloudy lens. The difference is how some early steps are done.
| Phaco (phacoemulsification) | Laser-assisted (femtosecond laser) | |
|---|---|---|
| Opening and lens capsule steps | Done by hand by the surgeon | Some steps are done by a laser |
| Removing the cataract | Ultrasound | Ultrasound, after laser softening |
| Visual results | Excellent for most people | Large studies show results similar to phaco for most people |
| Cost | Lower | Higher |
| Availability | Widely available | Available at fewer centres |
Which suits whom
- Phaco: It is the standard technique worldwide and gives excellent results for most people.
- Laser-assisted surgery: It may help in some specific situations. Your surgeon will tell you whether it offers any benefit for your eyes.
