We performed posterior chamber lens (PCL) implantation in 116 eyes of 93 diabetic patients, and examined pre- and postoperative visual functions to compare other operation methods. Compared with non-diabetic patients, there was no significant difference in postoperative visual acuity, and although diabetic patients had slightly more complications these were not severe. Among the various cataract operation methods for diabetic patients, the PCL group acquired best postoperative visual acuity, with least increase in retinopathy and largest postoperative dilated pupillary diameter. Diabetes mellitus patients with anterior chamber lens (ACL) implantation had severe complications, thus ACL is undesirable in these cases. ACL implantation is considered to be a contraindication, especially when capsular rupture occurs. Retinopathy of unoperated eyes, fellow eyes of those with PCL implantation and with increased retinopathy 6 months after operation became worse in 44% of cases. This result suggests that the progress of retinopathy after PCL implantation was mostly caused by the cataract operation itself, and the progressive nature of retinopathy. It is also suggested that the influence on retinopathy by implantation is relatively small. The position of PCL loops, patient age, HbA1c and general condition were related to the increase of retinopathy.
