Observation of AC-IOL implantation when the posterior cap-sule ruptured during the course of cataract operation.

Objective To evaluate the effect and security of the AC-IOL （anterior chamber intraocular lens） implantation when the posterior capsule ruptured during the course of cataract operation. Methods Posterior capsule rupturing and vitreous body entering into anterior chamber were found during the course of cataract operations in 27 patients （27 eyes）, then their anterior vitreous bodies were cutted and the flexzible open-loop AC-IOLs made with PMMA were implanted. Results In 1 week and 1 month after the operation, there were 85.2% and 88.9% patients （ eyesight ≥ 0. 3） , and there were 70. 4% and 81.5% patients （eyesight ≥ 0. 5） respectively. Complications such as corneal edema, uveitis and increased introcular tension recovered in 1 week after operation. The local angle conglutination was found around the open-loop. Conclusions Flexzible open-loop AC-IOL implantation which has the excellence of the simple operation, better eyesight resumption and less complications, can be considered as the first re-medial choice when the posterior chamber intraocular lens implantation failured.
