    CTR with Larger Dialysis

    Cataract/Anterior Segment

    With 6 to 8 clock hours of zonular dialysis, a CTR implanted prior to cortical cleanup can be a liability, as demonstrated in this case. There are not enough sufficiently strong zonules to redistribute forces, and the CTR may pin the cortex to the equatorial region of the bag. The lack of zonular counter-fixation makes it particularly difficult to strip cortex pinned by the CTR.
