Ultrasonic System for Cataract Characterization and Optimal Phacoemulsification Energy Evaluation

This study aims to assess the performance of an ultrasonic system for automatic classification of cataract type and severity, as well as the estimation of the optimal phacoemulsification energy. Ultrasonic signals from the lens will be acquired with the Experimental Medical Device (ESUS) in participants with cataract, and in healthy subjects (control). The proposed technique may represent an important advance in cataract treatment. The quantitative and automatic classification of cataract type and severity, and the estimation of the optimal phacoemulsification energy is may represent a valuable tool for surgical planning, reducing complications associated to excessive levels of phacoemulsification energy, as well as the times spent on surgeries. This device may be relevant not only for patients, but also for public health systems, reducing waiting lists and associated costs.
