Episode 37 - Phacoemulsification Physics

Welcome back to Basic Sciences in Ophthalmology.

I am your host Dr Thomas Whitelaw and in this episode, we will explore the physics underpinning phacoemulsification, the cornerstone of modern cataract surgery. Understanding how ultrasound energy interacts with ocular tissues essential not only for surgical efficiency but also for minimising complications such as thermal injury and endothelial damage.

We will break this down into three key areas:

1. Phaco handpiece physics

2. Ultrasound power modulation

3. Thermal safety and tip design
