Prospective evaluation of intraoperative @entity2790 stress XXXX during @entity231 surgery.

@entity1 @entity231 @entity174 @entity2790 @entity1642
PURPOSE: To determine the incidence and risk factors of @entity2790 ( @entity2790 ) stress @entity174 during @entity231 surgery. SETTING: Ivey Eye Institute, London, Ontario, Canada. DESIGN: Prospective, randomized cohort study. METHODS: @entity1 scheduled for routine @entity231 surgery were randomized into 2 study groups. The 2 groups only differed in the use of Monarch @entity2790 delivery cartridges for insertion of an Acrysof IQ SN60WF @entity2790 . The cartridge C group used Monarch cartridge C, and the cartridge D group used Monarch cartridge D. @entity1 were examined for @entity1642 . RESULTS: A total of 386 study eyes were enrolled. The overall incidence of @entity1642 was 6.22%. The incidence of @entity1642 with cartridge C and cartridge D groups were 3.16% and 9.18%, respectively (P = .01). The @entity1642 rate for @entity2790 power less than 18.0 D was 3.45%, @entity2790 power between 18.0 D to 23.5 D was 6.49%, and @entity2790 power over 23.5 D was 10.81%. A total of 24 @entity1642 were observed. Among @entity1642 , 45.8% were equal to or less than 1.0 mm in length. Two thirds of stress @entity174 were located over the central 4 mm of the @entity2790 optic. No subjective adverse visual outcomes were reported from any of the observed @entity1642 . CONCLUSION: Intraocular lens stress @entity174 is recognizable risk during @entity231 surgery. Risk factors for @entity1642 include @entity2790 cartridges and IOLs of higher refractive powers. There was a low risk for @entity1642 resulting in adverse subjective visual outcomes.
