Simulation and Design of Medical Devices

Bausch + Lomb Case Study

With the size of the incision directly related to post-surgical vision aberrations, engineers at Bausch + Lomb in Rochester, N.Y., have recently set an ambitious goal of enabling incisions as small as 1 mm incision goal – nearly half the current minimum incision size.

The Challenge

To understand the design engineering issues involved in the highly complex cataract surgical process in order to improve products, procedures, and post-surgery visual acuity.

Dassault Systèmes Response

Abaqus FEA from SIMULIA solves large nonlinear deformations and difficult self-contact issues, helping engineers visualize a complex biomedical application that cannot be measured physically.


Simulation of cataract surgical lenses, tools, and processes has shortened product design cycle iterations, decreased development costs, and improved product performance and surgical outcomes.
