[Influence of cataract and posterior chamber lens implantation on the dynamics of the aqueous humor. Prospective study in fluorophotometry].
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 aqueous humor flow was notified. This increase was highly significant (p less than 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 pseudo-facility.
