Preoperative and Intra-Operative Lens Hardness Measurement by Ultrasound
First Claim
1. A method of classifying a tissue region, the method comprising:
- using ultrasound energy to form an ultrasound image of the tissue region; and
forming a hardness profile of the tissue region based on the ultrasound image.

Abstract
The present disclosure provides methods, systems, techniques and apparatus related to an instrumentation used to classify tissue before and/or during removal. The tissue can include any hard tissue/soft tissue interface, such as a cataract within a lens. Before an operation, an ultrasound image can be provided that gives a full scan of the targeted region, e.g., a lens, and provide a hardness profile. The profile could include a two or three dimensional map of the tissue hardness, assisting a surgeon to choose a suitable surgical procedure and strategy. During the operation, hardness measurements can be carried out real-time, in a constant manner, while the surgeon is working. This data can allow the handpiece to automatically adjust to the surgical conditions including the tissue hardness, increasing surgical performance, decreasing surgical procedure time and reducing the rate of complications.
