Phacoemulsification Systems for Cataract Surgery

In cataract surgery, there is an ever present need to preserve the delicate structures of the eye while removing an opaque lens. The most modern method is phacoemuslification, whereby the lens is emulsified with ultrasound before being suctioned out. Phacoemulsification systems provide a platform for performing cataract surgery, as well anterior vitrectomy. For a phacoemulsification system, one of the most important features will be the suction/vacuum component. Pumping systems are usually peristaltic or Venturi (aspirating). Some phaco and vitrectomy systems have dedicated microprocessors to measure in-line vacuum pressure. Sonic needles, tips and probes are frequently sold separately.
