Dr. Claudio Trindade’s award-winning film (2014 ASCRS Film Festival) describes his novel small-aperture intraocular implant, which acts as a pinhole to improve vision in irregular corneal astigmatism. He has also used the device to extend the depth of focus in normal pseudophakic eyes. Made of black hydrophobic acrylic, the implant has a 1.5-mm central opening and is designed to be implanted in the ciliary sulcus, similar to a piggyback IOL. The implant material is transparent to infrared light, which allows fundus imaging after implantation.
