Sixty-seven patients were examined 3 to 5 1/2 (mean 4) months after intended extracapsular cataract extraction with implantation of the 3 M, style 83, posterior chamber lens. A visual acuity greater than or equal to 0.5 was recorded in 58 (86.6%) of the patients. The complications were: one (1.5%) case of acute iritis, one case of pupillary capture and two (3.0%) cases of capsulotomy-requiring early secondary cataract. There were no posterior segment complications. None of the patients were treated with anti-glaucomatous medication, and none had intraocular pressure above 20 mmHg. Pre-operatively, biometry was performed, and the SRK-formula was employed in estimating the post-operative spherical equivalent refraction: The actually measured refraction differed less than 2 diopters from the predicted refraction in 84.5% of the cases.

“…The group of patients, the surgical procedure, the per-operative and immediate post-operative complications, the postoperative treatment and post-operative gonioscopic findings have previously been described in detail by Nzser et al (1985). In a study of the same group of patients Hansen et al (1985) have given special attention to the intraocular pressure before and after surgery. All implants had a standard power of 19.0 D.…”

A report is given of visual outcome and intraocular complications in 64 patients 3-8 months after implantation of anterior chamber lens. 80% had a final visual acuity of 0.50 or better. Visual acuity below 0.50 could in most cases be related to pathological findings in the eye independent of implant. Pupillary block was found in 4 cases (6%), and at re-examination they all had gonioscopic changes. The mechanism of pupillary-block-glaucoma with IOL lens implantation and measures to meet this is discussed. Gross tucking was found to pre-dispose to chronic inflammation. Cystoid macular oedema (3%) and retinal detachment (2%) was found without obvious relationship to gonioscopic changes.

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 less than 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 less than P less than 0.2). We found a significant difference between the ECCE and ICCE groups in the IOP of the operated eye (P less than 0.001).
