Dr. Victor L. Caparas presented the CataPulse and it's Benefits.
The CataPulse Lens Removal System utilizes pulsed vacuum technology to remove the hardened lens. Phacoemulsification utilizes ultrasound.
What is Sonoluminescence?
Sonoluminescence is a phenomenon that occurs when a small gas bubble is acoustically suspended and periodically driven in a liquid solution at ultrasonic frequencies, resulting in bubble collapse, cavitation, and light and heat emmission.
For a good explanation of Sonoluminescence, watch this video.
Why is Sonoluninescence not good in Cataract Surgery?
Ultrasound creates Sonoluminescence. Sonoluminescence and ultrasound create Free Radicals. Free Radicals are atoms or molecules that are highly reactive with other cellular structures because they contain unpaired electrons. Free Radicals can cause damage to parts of cells such as proteins, DNA, and cell membranes by stealing their electrons through a process called oxidation.
For a great explanation of how Free Radicals are created during Phacoemulsification Cataract Surgery, watch this video.
