Phaco Machine
A phacoemulsification machine (commonly referred to as a phaco machine) is a medical device used during cataract surgery to remove the clouded lens (the cataract) from the eye and replace it with an intraocular lens (IOL). The phaco machine is essential in modern cataract surgery due to its ability to safely and effectively break up and remove the cataract material while minimizing damage to surrounding tissues.
Features and Technologies in Modern Phaco Machines
Active Fluidics:
This technology dynamically adjusts the irrigation and aspiration flow to maintain stable intraocular pressure (IOP) during the surgery, which is critical for preventing complications like iris prolapse or hyphema.
Ultrasound Modulation:
Modern phaco machines offer advanced ultrasound modulation, where the surgeon can control the intensity and frequency of the ultrasound energy in real-time. This allows for precise and safe cataract removal, even in challenging cases with harder cataracts.
Vacuum Control:
Phaco machines with vacuum control ensure that the aspiration (suction) is optimized to prevent tissue damage while removing cataract fragments.
Microincision Phacoemulsification:
Some modern phacoemulsification machines support microincision surgery, where even smaller incisions are used (as small as 1.8 mm), leading to faster recovery times and less postoperative astigmatism.
Automated Parameters Adjustment:
Advanced phaco systems may feature automatic adjustment of parameters based on real-time measurements, optimizing settings based on the cataract's hardness, the patient's eye anatomy, and surgical conditions.
