2. What are the problems?
1. Capsulorrhexis performed manually is not as
circular nor as perfectly sized as that performed
with a femtosecond laser.
2. Performance of toric IOLs depends accurate
alignment.
3. Expensive automatic imaging systems show
variable reliability, and steal light from the
surgeon’s view. They also have an annoyance
factor.
4. Parallax?
6. What is my solution?
A laser-etched contact lens with circular and
radial marks is used to guide manual
capsulorrhexis and toric IOL alignment
during cataract surgery.
8. Advantages
A simple cost-effective device for intraoperative
use that will allow surgeons without image
guidance systems to be more confident using
toric and multifocal intraocular lenses.
9. How is it used?
Intra operatively the contact lens is placed on
the corneal surface during cataract surgery and
the surgeon visualizes the guide lines.
