THE INFLUENCE OF CATARACT-EXTRACTION AND POSTERIOR CHAMBER LENS IMPLANTATION ON THE AQUEOUS-HUMOR DYNAMICS - A PROSPECTIVE FLUOROPHOTOMETRIC STUDY

The influence of posterior chamber lens implantation on the aqueous humor dynamics was investigated using anterior chamber fluorophotometry before and 9 weeks after cataract extraction and IOL implantation. 34 Patients finished the protocol. Patients with preexisting glaucoma or those having a history of ocular or systemic inflammation were excluded from the study, also those taking topical or systemic drugs with potential influence on the aqueous humor dynamics. 9 weeks after IOL implantation, a mean increase in aquesous humor flow was notified. This increase was highly significant (p < 0.01, Students paired t-test). There were no significant changes in aqueous humor dynamics in the unoperated, fellow eyes which served as controls. The significant difference of aqueous humor flow 9 weeks after cataract extraction and IOL implantation indicates that the liberation of prostaglandins may cause an increase of outflow facility as well as pseudofacility.
