Roundel phacoemulsification technique for in-the-bag intraocular lens fixation.

We introduce a new phacoemulsification technique that removes a cataract and retains a 5-mm round, tear-free opening in the anterior capsule, and present the results in 100 eyes. This technique is extremely useful in retaining the integrity of the capsular bag, which is indispensable for long-term capsular bag fixation, and is also a preliminary step in mastering endocapsular (intercapsular) phacoemulsification. We call this the roundel technique.
