OBJECTIVE: To evaluate the therapeutic effects and safety of the flexible open-loop anterior chamber intraocular lens (FOAC-IOL). METHODS: Using ultrasound biomicroscopy, the position of the haptics of FOAC-IOLs in 20 patients (20 eyes) and the relationship of the haptics with the iris and anterior chamber angle structures were observed postoperatively in order to evaluate the impact of these lenses on the structures of the ocular anterior segment. Duration of follow-up was six to 20 months. RESULTS: Of 40 IOL haptics, 26 were fixed at the recess of the chamber angle, and the other 14 had penetrated the iris and invaded into the ciliary stroma, causing recurrent uveitis. There was one eye with an eccentric lens. Eight eyes had anterior synechiae of the iris, which were related to the haptics of the IOL. CONCLUSIONS: Ultrasound biomicroscopy works well in the dynamic observation of the influence of IOLs on the ocular anterior segment. The haptics of FOAC-IOLs should be modified. LA: Chinese
