Objective: The study purpose was to compare effects of two porcine lens storage methods on phacoemulsification efficiency and chatter.
Methods: This in vitro laboratory study was conducted at the John A. Moran Eye Center Laboratories, University of Utah. Porcine nuclei were fixed in 10% formaldehyde and cut into 2.0 mm cubes. An equal number of lens cubes either were stored in a 100% humidity chamber or were partially immersed in balanced salt solution (BSS). Using identical parameters on the phacoemulsification machine, 40 lenses that underwent each storage method were phacoemulsified every two hours for a total of ten hours.
Results: Lenses stored in the 100% humidity chamber experienced a 2.25% increase in efficiency per hour (r2=0.1922; p=0.3846), while lenses stored partially .. View More»
