Researchers from the Departments of Mechanical Engineering and Ophthalmology led by Dr. Jean-Pierre Hubschman have developed a modified intralocular lens (IOL) and surgical implantation procedure to treat cataract and refractive anomalies.
Intraocular lenses (IOL) are used to treat eye refractive conditions like myopia, hyperopia, presbyopia and astigmatism. Implanting IOL’s require surgery and tools to help align the lens. Accurate positioning of the implant during surgery requires precise assessment of the ocular anatomy and precise alignment of the implant relative to the anatomical structures. This method relies on the steadiness of the surgeon’s hands and can be imprecise and can lead to complications if the surgeon’s calculations and manipulations are incorrect.
Researchers from the Departments of Mechanical Engineering and Ophthalmology led by Dr. Jean-Pierre Hubschman have developed a modified intralocular lens (IOL) and surgical implantation procedure. They have created an imaging system and an algorithm to precisely calculate the position and adjustments needed for correct placement of the IOL. The adjustments can be made by the surgeon or dictated to a robotic surgical interface. They have developed an IOL that pairs with their surgical procedure that allows for ease of position tracking with specialized marks on the IOL and rivets for ease of physical manipulation by the surgeon or robot. The top figure shows the surgical setup and the bottom figure shows the flow chart of how the IOL will be positioned.
