Flared phacoemulsification @entity3455 to decrease ultrasound time and energy in XXXX surgery.

PURPOSE: To determine the effect on ultrasound (US) time and energy of using flared phacoemulsification @entity3455 in @entity231 surgery. SETTING: Private referral practice of Pacific Cataract _ Laser Institute, Chehalis, Washington, USA. METHODS: One surgeon using the Allergan Medical Optics Diplomate phacoemulsification machine performed @entity231 surgery by a single divide-and-conquer technique. A prospective nonmasked consecutive study group (n = 262) was selected from @entity1 operated on with phaco @entity3455 flared by 25%. A consecutive control group (n = 440) was selected from @entity1 having surgery using the same technique except for the use of straight phaco @entity3455 . The study group had @entity231 surgery over a 5 week period and the control group, over an earlier 10 week period. Two weeks separated the groups. Cases complicated by @entity393 were eliminated. The 2 groups were compared by age, sex, @entity348 ( @entity348 , the total time ultrasound energy was applied), and equivalent phaco time (EPT, the product of the phaco time elapsed and the phaco energy). RESULTS: One @entity1 in each group was eliminated for @entity393 during surgery. There were no significant differences in age, sex, or eye between the 2 groups. The study group had a mean @entity348 of 29.2 seconds +/- 11.7 (SD) (range 0 to 88 seconds) and a mean EPT of 16.4 +/- 8.6 seconds (range 0 to 67 seconds). The control group had a mean @entity348 of 34.4 +/- 16.1 seconds (range 0 to 130 seconds) (P <.001) and a mean EPT of 20.0 +/- 12.8 seconds (range 0 to 107 seconds) (P <.001). CONCLUSION: Flared ultrasonic phacoemulsification @entity3455 significantly reduced the US time and energy used in @entity231 surgery.
