Bausch & Lomb developed a new computer simulation process to confidently suggest the most appropriate set of multifocal contact lenses to customers, using fewer clinical tests. The team used Optimus to easily integrate optical modeling software Zemax and technical computing software MATLAB, the latter managing the inbound clinical test data.

What you will read in this case study:

• Setting up reliable models for eye biometry and eyesight deficiencies

Computer eye models have been utilized for decades to represent a wide range of properties of the human eye, but often fail to predict the true accommodative eye response. Optimus helped streamline the process of simulating and correlating digital eye models to build a solid base of reliable models that account for a wide range of patient-specific parameters.

• Simulating patients' realistic use of multifocal contact lenses

Using eye models of patients facing mature presbyopia, Bausch & Lomb predicted eyesight sharpness in relation to five novel multifocal contact lens designs. Using Optimus, Bausch & Lomb validated that correlation between predicted acuity and acuity performance derived from clinical tests fell between 90 and 97%.

• A validated process to deliver personalized eyewear with maximum confidence

Validating the simulation process to predict eyesight sharpness combining individual eye models and various contact lens designs, paves the way for a higher degree of personalized medical care in eyewear with maximum confidence and minimum clinical testing.
