目的：研究青壮年连续环形撕后囊的优点及方法。方法：将90只青年尸眼（平均26．17岁）随机分为后囊中央线状切开组及连续环形撕后囊（PCCC）组处理后囊膜，然后注水提高玻璃体腔压力至玻璃体脱出，观察后囊膜变化情况。结果：前组全部出现切口延长，至少一端到达赤道部，平均注水量1．01ml；后组撕开口边缘完整，无放射状撕裂，直径增大了1．13mm，注水量为1．51ml，两组注水量比较有显著意义。结论：连续环形后囊撕开口较线形切开口有更强的抗张性。
Objective: To study the advantages and methods of continuous annular posterior torn posterior capsule in young adults. Methods: 90 young corpse (average 26.17 years old) were randomly divided into central posterior capsule incision group and continuous annular posterior capsular bag (PCCC) group to treat the posterior capsule, and then water injection to increase vitreous cavity pressure to vitreous prolapse , Observe the changes of posterior capsule. Results: All the incisions in the anterior group were prolonged with at least one end reaching the equator, with an average water volume of 1.01ml. The posterior group had intact edge with no radial tear, the diameter increased by 1.13mm, the amount of water injected was 1.51ml, Two groups of water more significant. CONCLUSION: The continuous annular posterior capsulotomy has stronger tensile strength than the linear incision.
