Methods
The medical records of consecutive patients at the Wills Eye Institute Retina Service from March 11, 2008 to June 17, 2008 who underwent PPV for retained lens fragments after complicated cataract surgery were retrospectively reviewed. Patients were referred at different times after cataract surgery and underwent PPV at the discretion of the retinal surgeon. Preoperative, intraoperative, and postoperative patient data were collected from the medical records, including patient demographics,
Results
Twenty eyes of 20 patients underwent PPV for retained lens material following complicated cataract surgery (see Table). The initial surgery in every case was small-incision phacoemulsification for a visually significant cataract. The mean follow-up duration was 16 weeks (range 5 to 32 weeks). An intraocular lens was placed at the time of the initial surgery in 17 eyes. Three eyes were left aphakic after their initial surgery and a secondary intraocular lens was placed during their second
Discussion
Recent advances in vitreoretinal surgery have enabled surgeons to perform small-incision, sutureless PPV and have provided different options for handling retained lens material after complicated cataract extraction. Machemer revolutionized the field of vitreoretinal surgery when he introduced PPV in 1972 using a single-port, 17-gauge vitrector system.6 In 1975 O'Malley and Heintz reported the use of 20-gauge instrumentation for PPV, which became the standard of care for many years.7 Over the
