摘要
目的分析白内障患者角膜不规则散光(corneal irregular astigmatism,CIA)与眼轴长(axial length,AL)相关情况调查及预估白内障术后视力。方法收集697例白内障患眼,分析角膜CIA对术后视力恢复的指导意义。结果CIA与AL相关情况:AL<22 mm患眼中,CIA<0.1比例为0,0.1≤CIA<0.3比例72.41%,0.3≤CIA<0.6比例13.79%,0.6≤CIA比例13.79%;22 mm≤AL<24 mm患眼中以上各区间患眼比例分别为3.73%、77.33%、15.20%及3.73%;24 mm≤AL<26 mm患眼中各比例变化为11.01%、70.33%、14.41%及4.24%;26 mm≤AL<28 mm组为5.88%、72.55%、13.73%及7.84%;28 mm≤AL<30 mm组以上各区间患眼比例分别为10.91%、70.91%、10.91%及7.27%;30 mm≤AL组以上各类数据为13.04%、66.67%、13.04%及7.25%。各眼轴组的CIA水平整体上差异无统计学意义(P>0.05)。CIA与白内障术后视力情况:随着CIA的增高,患眼术后恢复至0.7及以上的比例减少。当CIA高于0.4以上时,术后近一半患者视力恢复不超过0.7,能恢复到0.9以上者更少,不超过10%。结论白内障患眼各眼轴长组,0.1≤CIA<0.3范围内患眼比例最高,达近70%。术前对白内障患者行视觉分析仪检测角膜CIA大小有助于对患眼术后视力进行预测。
Objective To analyze the related investigation of corneal irregular astigmatism(CIA)and axial length(AL)in cataract patients and predict vision after cataract surgery.Methods A total of 697 cases of cataract eyes were collected and analyzed the guiding significance for restoring vision after cataract surgery.Results CIA and AL related informations:in the AL<22 mm affected eye,the CIA<0.1 ratio was 0,0.1≤CIA<0.3 ratio was 72.41%,0.3≤CIA<0.6 ratio was 13.79%,and 0.6≤CIA ratio was 13.79%.The proportions of affected eyes in the above-mentioned areas of 22 mm≤AL<24 mm were 3.73%,77.33%,15.20% and 3.73%,respectively.The proportion changes of afftected eyes in 24 mm≤ AL<26 mm were 11.01%,70.33%,14.41% and 4.24%in sequence.The proportion changes of 26 mm≤AL<28 mm respectively were 5.88%,72.55%,13.73% and 7.84%.The proportions of affected eyes in the above-mentioned areas of 28 mm≤AL<30 mm were 10.91%,70.91%,10.91% and 7.27%.The data of 30 mm ≤ Al were 13.04%,66.67%,13.04% and 7.25%.No differences were found in the CIA levels between the various axial groups(P>0.05).CIA and Vision after cataract surgery:with the increase of CIA,the proportion of the affected eyes back to 0.7 and more after surgery were decreased.When CIA was higher than 0.4,nearly half of the affected eyes restored at most 0.7,and those who recovered to above 0.9 were even less,not more than 10%.Conclusion The proportion of affected eyes are the highest in the range of 0.1≤CIA<0.3 among the various AL groups,reaching nearly 70%.Preoperative visual analyzer for cataract patients to detect CIA levels can contribute to predicting the vision of affected eyes after cataract surgery.
