目的观察有晶状体眼后房型人工晶状体(ICL)植入术后患者在缩瞳与散瞳状态下眼前段参数的变化.方法自身对照研究随机选取ICL植入术后2周以上的患者10名(19眼),滴1％毛果芸香碱或复方托吡卡胺分别建立缩瞳和散瞳状态下的模型,然后采用眼前段光学相干断层扫描仪分别测量自然状态、缩瞳状态和散瞳状态下的前房深度、ICL拱高及角膜白对白间距等眼前段相关参数.对相关数据进行配对f检验.结果自然状态、缩瞳和散瞳后的前房深度分别为(3.61±0.20)mm、(3.42±0.15)mm和(3.64±0.22)mm,缩瞳状态下的前房深度较自然状态浅,差异有统计学意义(t=7.89,P＜0.01),散随状态下的前房深度与自然状态无明月显差异.自然状态、缩瞳和散瞳后的ICL拱高分别为(0.61±0.14)mm、(0.41±0.10)mm和(0.64±0.14) mm,缩瞳状态下的ICL拱高较自然状态明显降低,差异有统计学意义(t=10.51,P＜0.01),而散瞳状态下的ICL拱高与自然状态相比差异无统计学意义.自然状态、缩瞳和散瞳后的角膜白对白间距分别为( 11.40±0.28)mm、(11.38±0.32 )mm和(11.35±0.30)mm,差异均无统计学意义结论 ICL植入术后患者的眼前段参数在缩瞳(类似处于强光环境)与散瞳(类似处于暗光环境)状态下的变化可保持在安全范围内.

Objective To investigate anterior segment variations under miotic and mydriasic conditions in patients with a posterior chamber implantabble collamer lens (ICL).Methods Ten patients (19 eyes) who underwent ICL implantation surgery at least two weeks prior were enrolled randomly in this self-controlled study.One percent pilocarpine or compound tropicamidc was administered to induce miosis or mydriasis,simulating responses to bright light or dark condifions.Parameters of the anterior segment under normal light conditions without eye drops,and with miosis and mydriasis were measured with anterier segment-optical coherence tomography,including anterior chamber depth (ACD),ICL vaulting and the white-to-white (WTW) distance.A paired t test was used to analyze the data.Results ACI) was 3.61±0.20 mm under normal conditions,3.42±0.15 mm under miosis and 3.64 ±0.22 mm under mydriasis.ACD in miosis was significantly shallower than under normal conditions (t=7.89,P＜0.01),while there was no difference between ACD in mydriasis and normal conditions.Vaulting was 0.61±0.14 mm under normal conditions,0.41±0.10 mm in miosis and 0.64±0.14 mm in mydriasis.Vaulting in miosis was significautly narrower than under normal conditions (t=10.51,P＜0.01),while there was no difference between vaulling in mydriasis and normal conditions.WTW distance was 11.40±0.28 mm under normal conditions,11.38±0.32 mm in miosis and 11.35±0.30 mm in mydriasis.There was no difference between WTW in miosis,mydriasis or normal conditions.Conclusion The anterior segment variations of patients with ICL under miosis or mydriasis stayed within a safe range.
