A prospective study of intraocular pressure four months after extracapsular cataract extraction with implantation of posterior chamber lenses

Abstract

Sixty-six consecutive cases of extracapsular cataract extraction (ECCE) and sulcus implantation of a posterior chamber lens had intraocular pressure (IOP) measurements recorded four months postoperatively. These results were compared to the fellow unoperated eyes, as well as to a group of 64 patients, whom we reported previously, who had intracapsular cataract extraction (ICCE) and implantation of an anterior chamber lens. The ECCE and posterior chamber lens group demonstrated a significant reduction in the IOP of the operated eye after four months (P < 0.001), with none of the patients having an IOP greater than 20 mm Hg. No significant IOP change could be demonstrated in the fellow eye (0.1 < P < 0.02). We found a significant difference between the ECCE and ICCE groups in the IOP of the operated eye (P < 0.001).
