Abstract:
We describe the case of a 78-year-old highly myopic woman who had bilateral phacoemulsification with posterior chamber intraocular lens implantation. During surgery, the anterior chamber was extremely deep and the pupil was excessively dilated, consistent with lens-iris diaphragm retropulsion syndrome (LIDRS). Subsequent biomicroscopy revealed multifocal iris sphincter ruptures, a new finding associated with LIDRS.
