Typical Use
Emulsify and aspirate cataractous lens material during cataract extraction.
Description
A handheld ultrasonic device that vibrates at high frequency to fragment the lens nucleus while simultaneous irrigation and aspiration maintain anterior chamber stability and remove emulsified material, enabling small incision cataract surgery with rapid visual recovery. Phaco technique requires precise fluidics control, appropriate tip selection, and surgeon skill to minimize endothelial cell loss, posterior capsule rupture, and postoperative inflammation; viscoelastic agents protect intraocular structures during the procedure. Postoperative care includes anti inflammatory and antibiotic regimens, intraocular pressure monitoring, and refractive assessment to optimize visual outcomes. Advances in phaco technology and intraocular lens design have transformed cataract surgery into a high volume, low complication procedure with excellent patient satisfaction.
