PURPOSE: This study aims to demonstrate and quantify corneal incision temperature during phacoemulsification using two platforms operating at different frequencies (28.5 kHz vs 44.5 kHz).

METHODS: Bench: Two phaco needles were tested as part of bench data: B+L 1.8 MICS (A), Alcon Balanced Tip (B). The Needles were operated on Stellaris Elite (28.5 kHz) and Centurion (44.5 kHz) in continuous mode with equal stroke lengths, isolating frequency as a single variable. The Needles were submerged in 2.5 ml BSS and temperature rise was measured with a thermocouple during 5 and 10 second activations. Clinical: Corneal incision temperature was recorded during surgeries on both systems with a Thermal IR camera to record corneal incision temperatures.

RESULTS: TBD

CONCLUSION: TBD
