At the sharp end

Hoya Surgical Products now has, what it claims to be, the Sharpest Edge on the market. The yellow aspheric blue-light filter IOLS iSymm has undergone a unique manufacturing process which makes it the sharpest of all commercially available IOLs currently in the market.

Professors Liliana Werner and Manfred Tetz have been studying the edge profiles of currently available IOLs and their recent improvements and their research is to be published in the European Opthalmic Review (Vol 3 Issue 2). Its conclusions are that their analysis revealed “a large variation of deviation from a perfect square, as well as mean values that were higher for hydrophilic acrylic lenses in comparison with values reported for hydrophobic acrylic and silicone lenses. Only existing and future clinical data will help us better understand the effect of microedge structure and design on reducing posterior capsule opacification (PCO), but perhaps a cut-off value to clinically label an IOL as square-edged should be sought. The methodology used in such studies can help optimise the edge profile of IOLS.”

Another positive announcement from the company is that HOYA received the FDA Approval for the iSert preloaded implantation system in the USA. “This big step allows HOYA Surgical Optics now to introduce the first and only preloaded intraocular lens injection system in the US,” said Hoya's head of marketing, Mike Galloway.

Galloway also confirmed that HOYA Surgical Optics will provide ophthalmologists with advanced products and professional services with plenty of ideas in the pipeline.
