What are the problems?Capsulorrhexis performed manually is not as circular nor as perfectly sized as that performed with a femtosecond laser.Performance of toric IOLs depends accurate alignment.Expensive automatic imaging systems show variable reliability, and steal light from the surgeons view. They also have an annoyance factor. Parallax?

Verion axis 75 ?head tilt

Verion axis 78 ?head tilt

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.

Circular marks at 5, 6 and 7mm, and radial marks every 5

AdvantagesA 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.

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.
