AMSTERDAM — Surgeons striving for quality of vision in their post-cataract surgery patients must take into account the possibility of postoperative photic phenomena, said Olivia Serdarevic, MD, here at the XIX Congress of the ESCRS.

Lenses with high refractive indices and flat anterior surfaces are more likely to cause disturbing glare symptoms, Dr. Serdarevic said. The source of glare in these IOLs is internal retinal reflection, she said.

The CeeOn lens from Pharmacia has addressed this issue and other problems as well, such as posterior capsular opacification, Dr. Serdarevic said, by offering a square-edged optic with a lower refractive index and steep anterior surface.

Cataract surgeons must balance different aspects of IOL performance in order to provide excellent visual results after cataract surgery, Dr. Serdarevic said. Cataract surgeons will increasingly demand better performing materials and designs and patients will expect better results from cataract surgery as well, she said.
