The 18 chapters cover prevention, including instrumentation and techniques, the approach to posterior polar cataracts, small pupils and intraoperative floppy-iris syndrome, and subluxated cataracts; management of the rupture, anterior vitrectomy techniques, and salvaging lens material; implantation of posterior chamber lenses in the setting of limited or no posterior capsular support, including intraocular lens (IOL) scaffold and glued IOL scaffold techniques and sutured IOLs; and complications associated with rupture, including dislocated IOLs, corneal damage, chronic inflammation, cystoid macular edema, and postoperative endophthalmitis.
Acknowledging that even the most experienced cataract surgeon can encounter unfortunate circumstances, the contributors describe aspects of the edgier side of procedures, such as subluxated cataracts, dislocated lens fragments, suprahard or posterior polar cataracts, infectious endophthalmitis, and miotic pupils.
