Abstract
Intracapsular cataract extraction employing a corneal incision and with implantation of the semiflexible McGhan/3 M, style 70, anterior chamber lens was performed in a group of 25 patients with senile cataract. Intraocular pressure (IOP) was measured prior to and daily in the 1st 4 days after the operation. IOP was slightly, but significantly (P .ltoreq. 0.05) lower in the observed post-operative period as compared to the pre-operative measurement. Similar results have previously been found after cataract extraction with an identical technique, but without lens implantation. This probably means that early post-operative intraocular homeostasis with respect to IOP is unaffected by the implantation of this type of lens. The fine regulation of early post-operative IOP is probably related to the fact that the described surgical technique usually is associated with only minor gonioscopically visible changes of the trabecular meshwork.
