目的 :探讨单眼无晶状体眼对眼球的影响。方法 :收集近几年单眼外伤性无晶状体眼和老年性白内障摘除后无晶状体眼行二期植入术的病例 5 9例。选有完整资料的外伤组 19例 ,老年组 2 7例。测定无晶状体眼和对侧眼眼轴长度 ,比较双侧眼轴 ,并观察无晶状体眼与病程的相关性。结果 :外伤组的无晶状体眼眼轴较对侧眼明显增长 ,其增长程度与病程有正相关性。尚未发现老年组有类似情况 ,但是有 5例单眼老年性白内障摘除 8年以上的无晶状体眼的眼轴较对侧眼长。结论 :多发生在青壮年期的外伤性无晶状体眼可以重新诱发眼球轴性生长。本组资料尚不能证明老年无晶状体眼对眼球的作用 ,但是可能诱发眼球生长的因素终生存在。临床上拟行二期人工晶状体植入术时应注意对眼轴的影响 ,以利于术后的双眼平衡
Objective: To investigate the effect of monocular aphakia on the eyeball. Methods: Fifty-nine cases of aphakic traumatic ametropia and senile cataract in two years after phacoemulsification were collected. 19 cases of trauma group selected with complete data and 27 cases of elderly group. Aphakia and contralateral ocular axial length were measured, bilateral ocular axis was compared, and the correlation between aphakia and duration of disease was observed. Results: In the traumatic group, the axial length of the aphakia was significantly increased compared with that of the contralateral eye. The degree of its growth was positively correlated with the duration of the disease. A similar situation has not been found in the elderly group, but in 5 cases of monocular senile cataract more than 8 years of removal of the lens axis longer than the contralateral eye. CONCLUSIONS: Traumatic aphakia, which occurs mostly in adolescence, can re-induce ocular axis growth. The information in this group can not prove that the role of the elderly aphakia on the eye, but may cause eyeball growth factors exist for life. Clinically planned second-stage intraocular lens implantation should pay attention to the impact on the ocular axis in order to facilitate postoperative balance of both eyes
