New diffractive lens shows promise

The first results of an ongoing multicentre study in France suggest that a new diffractive intraocular lens (IOL), Diffractiva-s (HumanOptics), offers good visual results.

Four centres across France (Paris, Toulouse, Marseille & St. Jean de Luz) are evaluating the three-piece silicone implant, which has nine diffractive zones. So far, surgeons have reported that the lens offers stable centration with no halo or glare effects. Good visual results in near vision are allowing patients to read small newspaper print, however, intermediate and far vision are still subject to further research.

Further results from the study will be presented at this year's ASCRS meeting in Chicago, USA and the SFO meeting in Paris.
