Intraocular Device for Correction of Aphakia and Restoration of Accommodation


­Background on CU3886H
Over 2 million cataract surgeries are performed each year in the U.S. Currently, there are 3 million patients with glaucoma in the U.S. Everyone over the age of 50 will eventually lose their accommodative ability, requiring the use of reading glasses in most individuals. There is no singular device that addresses all three conditions; rather, multiple procedures are performed to correct for these. Typically, a cataract and glaucoma surgery can be performed on the same day but increases the operating time and time under anesthesia. A single minute of operating room time can cost $150 or more. Accommodative intraocular lens are undergoing clinical trials but none treats glaucoma simultaneously.

Technical Innovation
Dr. Jeffrey Olson has created a small, injectable prosthetic which is placed in the eye at the time of or following cataract surgery. The device has a central ring, which is used to hold an intraocular lens, and a plurality of arms that radiate outward from the central ring. A foot plate on the end of each arm allows the device to push out laterally against the ciliary body. This device allows for stable and precise placement of the intraocular lens, restores the accommodative ability to the eye (as the ciliary body relaxes and contracts with accommodative effort, the footplates are pushed, causing the intraocular lens to move forward and backward), and decreases aqueous productions and subsequently decreases intraocular pressure via counter-pressure on the ciliary body. This has been tested ex vivo in porcine eyes. The inventor believes this can be the first on the market to address multiple conditions with a sophisticated yet easy-to-use device.
