The platform also provides detailed feedback.Thekey pointaddresses the subject matter knowledge necessary to answer the question correctly.
Key Point:Intraoperative maneuvers to help reduce the effects of floppy iris syndrome include reducing the aspiration flow rate and vacuum, use of mechanical iris expansion devices, placement of intracameral epinephrine, use of highly retentive viscoelastic, and avoiding an incision that is too large or too posterior (to reduce risk of iris prolapse).
