Tekia accommodating intraocular lens
Though IOLs enable many patients to have reduced dependence on glasses, most patients still rely on glasses for certain activities, such as reading. That first intraocular lens was manufactured by the Rayner company of Brighton, East Sussex, England from Perspex CQ made by ICI.
IOL implantation carries several risks associated with eye surgeries, such as infection, loosening of the lens, lens rotation, inflammation, night time halos.
The distance and near visual acuities, contrast sensitivity, and accommodation were measured over a 1-year follow-up period.
Accommodation was measured subjectively, using defocus curves, and objectively, with an open-field autorefractor.
Advances in technology have brought about the use of silicone and acrylic, both of which are soft foldable inert materials.
This allows the lens to be folded and inserted into the eye through a smaller incision.
