This video covers the benefits and drawbacks of trifocal IOLs, which have been getting attention in Europe for improving near, far, and intermediate vision. Dr. Erik Mertens narrates video of a FineVision trifocal IOL implantation and Dr. Jan Jorgensen discusses results with the AT Lisa Tri toric IOL. After implantation, patients can see 20/20 at near and far distances and 20/30 at intermediate. The lens can also treat astigmatism. However, halos, glare, and contrast issues are side effects that must be discussed with patients beforehand. Many patients for this lens are younger than typical cataract patients, and patients tend to be happy with the results.
