Intraocular pressure after extracapsular cataract extraction with implantation of posterior chamber lenses

ABSTRACT

The intraocular pressure (IOP) in 115 cases of extracapsular cataract extraction (ECCE) and ciliary sulcus fixation of posterior chamber lens implantation was measured more than 2 months postoperatively. These results were compared to the unoperated fellow eyes, as well as to a group of 14 patients who had ECCE and implantation of an anterior chamber lens. The posterior chamber lens implanted eyes demonstrated a significant IOP reduction after surgery compared to the unoperated fellow eyes and the anterior chamber lens implanted eyes. In the posterior chamber lens implanted eyes, there was a significant IOP reduction after surgery in all age groups and there was a significant IOP reduction in the eyes with a 2 to 6 months and a 7 to 12 months follow-up after surgery, but no IOP change in the eyes with more than 1 year follow-up after surgery. We concluded that in the case of ECCE and ciliary sulcus fixation of posterior chamber lens implantation, IOP was initially reduced after surgery, but approarhed the preoperative level over a period of time.
