The effect of anterior vitrectomy with different opportunity of operation in cataract from penetrable eye trauma

Objective Objective To explore the effects of anterior vitrectomy in cataract from penetrable eye trauma. Methods In 58 cases（58 eyes）of cataract with cracked posterior capsule caused by penetrable eye trauma（during Jan 2008-Feb 2009）,debridement and cataract extraction plus anterior vitrectomy were performed to 32 cases（32 eyes）; The other 26 cases（26 eyes）only underwent debridement,and cataract extraction plus anterior vitrectomy were performed 1 week-1 month later o The follow-up were 1 to 3 months.The best corrected visual acuity and the comlications wereanalyzed. Results In the 32 eyes group,the BCVA was 0.1～0.8,including of 1 eye 0.1,7 eyes 0.2～0.3,24 eyes 0.4～0.8.Only 1 eye underwent vitrectomy through pars plana because of high inner optic pressure o In the 26 eyes group,the BCVA was CF～0.8,including of 3 eye≤0.1,7 eyes 0.2～0.3,16 eyes 0.4～0.8.4 eyes underwent cataract extraction plus anterior vitrectomy in 1 week because of high inner optic pressure,and 2 of them continued vitrectomy through pars plana.The complications of group 2 were more and much severe than group 1. Conclusions Cataract extraction plus anterior vitrectomy is very effective for the cataract with cracked posterior capsule caused by penetrable eye trauma,and will reduce the complications,the difficulties and risks of later surgery thus achieve better BCVA and visual function.
