Persistently raised intraocular pressure following extracapsular cataract extraction

In this population based study we have reviewed the files of all patients who underwent an extracapsular cataract extraction (ECCE) between 1984 and 1987, were normotensives prior to surgery, and were followed up for at least 10 months after the ECCE. From a total of 1047 operations 746 qualified for the inclusion criteria; of these, 16 (2.1%) were found to have a consistently raised intraocular pressure (>21 mmHg) on more than two occasions) at four months or later after surgery and throughout at least a sixmonth period. An increased incidence of secondary aphakic glaucoma was associated with anterior chamber IOL implantation (p<000l) and posterior capsule rupture (p<0.0l), but not with any of the other variables examined (age, sex, surgeon).
