What procedure uses ultrasound for cataract removal?

Phacoemulsification is a technique that employs ultrasound technology to effectively remove cataracts. In this procedure, the ultrasonic energy is utilized to break up the cloudy lens material into tiny fragments, which can then be easily aspirated from the eye. This method is highly regarded due to its minimally invasive nature, allowing for a smaller incision compared to traditional cataract surgery techniques.

The effectiveness of phacoemulsification stems from its ability to utilize ultrasound waves to emulsify the lens, thus facilitating a quicker recovery and reducing potential complications associated with larger incisions that might be required by other procedures.

In contrast, extracapsular extraction is typically associated with a larger incision to remove the cataract in one piece and does not use ultrasound. Endoscopic cataract surgery and laser-assisted cataract surgery may utilize advanced technologies but are not primarily based on ultrasound to break down the lens. Therefore, phacoemulsification stands out as the most relevant and traditional method using ultrasound for cataract removal.
