Self-repositioned IOL in a vitrectomized eye.

摘要

I would like to address some important issues raised by Mansouri's report of a self-repositioned intraocular lens (IOL) in a vitrectomized eye.First, it is not clear when the radial tear at the 9:30 o'clock position occurred. I question whether it occurred during placement of a foldable single-piece plate-haptic acrylic IOL such as the Acri.Smart 48 S (Acri.Tech). The tear might have occurred during capsulorhexis or phacoemulsification or there might have been a preexisting posterior capsule defect that occurred during the previous pars plana vitrectomy. Consulting the retinal surgeon and/or carefully studying the surgical notes might reveal posterior capsule injuries during vitreoretinal surgery. If there arecapsular injuries before surgery, phacoemulsification, especially microincision cataract surgery, may cause the nucleus to drop. Using an inflow through the pars plana and traditional extracapsular cataract surgery seems safer in this situation.
