This early feasibility study aims to improve near vision in subjects 55 years or older who have a clinical diagnosis of Age-Related Macular Degeneration. Subjects must have previously been implanted with either the Alcon Model SN60WF or Model SA60AT intraocular lens at least 6-months prior to receiving the IOPCL (intraocular pseudophakic capsular lens). Subject will be followed for a period of 12-months.
This will be a 12-month study, in which a maximum of 10 pseudophakic subjects from up to three clinical sites with a diagnosis of age-related macular degeneration will be enrolled. The IOPCL MAG (intraocular pseudophakic capsular lens magnifier) consists of a 4.5mm diameter optic. The IOPCL MAG is centered above the existing intraocular lens. The IOPCL MAG is designed to improve near vision of the AMD subject by providing magnification of 10 diopters in the central 1.8mm zone of the lens optic.
The primary objective of this study is to determine the stability of the IOPCL-AMD-MAG to successfully adhere to a pseudophakic intraocular lens (PCIOL) without slippage or rotation.
The secondary objective of this study is to determine if the IOPCL-AMD-MAG can improve uncorrected near vision in subjects previously implanted with the Alcon Models SN60WF or SA60AT.
Outcome simulation testing will be performed prior to the subject receiving the IOPCL. To qualify for the study the subject must demonstrate an improvement in uncorrected near visual acuity of 10 letters over baseline.
