Abstract: With 30 million interventions a year worldwide, cataract surgery is one of the most frequently performed procedures. Yet, no tool currently allows teaching all steps of the procedure without putting patients at risk. A particularly challenging stage of this surgery deals with the injection and deployment of the intra-ocular lens implant. In this paper we propose to rely on shell theory to accurately describe the complex deformations of the implant. Our approach extends the co-rotational method used in finite e… Show more

“…In-depth descriptions can be found in the referenced literature, i.e. [6,7]. The novel joining approach for meshes, which can be separated into rest shape mapping prior to simulation and rest shape relaxation during simulation, is described subsequently and its limitations regarding possibly necessary mesh preprocessing conclude this section.…”

“…This will lead to loss of remaining hearing, damages to auditory nerve dendrites and fibrosis. To represent the Basilar membrane, we use a shell model [6] that derives from a combination of a triangular in-plane membrane element and a triangular thin plate in bending. The nodes of the membrane that are connected with the walls of the cochlea are fixed, like in the real case.…”

“…In the current scenario, cases of cataracts leading to blindness are likely to advance due to an ageing population and shortage of required healthcare infrastructure in low and middle-income countries [3]. World Health Organization (WHO) defines a cataract as clouding of the lens of the eye, which impedes the passage of light [4]. Normally, the lens is a completely clear image.…”
