Surgical techniques in phacoemulsification.

PURPOSE OF REVIEW: Recent advances in cataract surgical techniques are described, focusing on the evolution towards less traumatic surgery. RECENT FINDINGS: Smaller incisions, split infusion, astigmatic management, and techniques of managing floppy iris syndrome are significant changes in the cataract surgical technique within the last 12-24 months. SUMMARY: Surgeons need to learn the new techniques and instrumentation as cataract surgery moves towards less invasive surgery, with smaller incisions, more precise refractive outcomes, and fewer complications.

Phaco fluidics and phaco ultrasound power modulations.

The most common surgical procedure in the United States is cataract surgery; most specifically, phacoemulsification. Understanding the fluidics and ultrasonic power fundamentals for phacoemulsification is instrumental for their safe and efficient use. Although phaco machines allow a few decades ago, the basic concepts have remained the same. Phaco machines allow ultrasonic-assisted aspiration of the cataract while maintaining the stability within the eye and minimizing the trauma of surgery to ocular structures. In this light, the two primary concepts are the fluidics of the lens aspiration and the application of the ultrasound power.
