INTRAOCULAR-PRESSURE 7 YEARS AFTER EXTRACAPSULAR CATARACT-EXTRACTION AND SULCUS IMPLANTATION OF A POSTERIOR CHAMBER INTRAOCULAR-LENS

Seven years after extracapsular cataract extraction (ECCE) and sulcus implantation of a posterior chamber intraocular lens, we measured the intraocular pressure (IOP) in 28 eyes of 28 patients. The results were compared with the preoperative IOP and with the postoperative IOP at four months and 2 1/2 years. The mean IOP value seven years after surg ery was 1.3 mm Hg lower than the preoperative mean value. No significa nt difference was found among the values at four months, 2 1/2 years, and seven years. One patient experienced a marked rise in IOP between 2 1/2 years and seven years and was excluded from the calculations. Ho wever, we could not tell whether it was a consequence of the cataract surgery. In this study, we found that IOP stabilized at a postoperativ e level that was significantly lower than the preoperative value and h as remained there for seven years.
