摘要: 目的 探讨波前像差在白内障超声乳化吸除联合人工晶状体植入术后晶状体后囊膜混浊患者视功能评价中的意义。方法 收集于我院就诊的晶状体后囊膜混浊患者 33 例(38 只眼),最佳矫正视力≥0.6,排除眼部合并有其他疾病史及 iTrace 视 觉功能分析仪不能准确测量的患者,行 Nd:YAG 激光晶状体后囊膜切开术(晶状体后囊膜切开直径约为 5 mm)。分别于手术前 后进行波前像差检查,并进行统计学分析。结果 术前与术后最佳矫正视力的差异无统计学意义(P > 0.05),术后 1 h 眼压、房 水荧光值与术前比较,差异均无统计学意义(P > 0.05)。术后球镜度、波前像差中总像差、总高阶像差均较术前明显下降(3.0 和5.0 mm 瞳孔下),差异有统计学意义(P < 0.05)。术后 3 个月无视网膜脱离、黄斑囊样水肿和人工晶状体移位等并发症发生。结论 波前像差可灵敏、客观地反映人工晶状体眼合并晶状体后囊膜混浊的视功能状态,可为 Nd:YAG 激光治疗人工晶状体眼后 囊膜混浊手术时机的选择提供参考依据。

Abstract: Objective To explore the clinical significance of wavefront aberrations in the evaluation of visual function in patients with posterior capsule opacification(PCO)and provide timing criterion for performing neodymium:yttrium aluminum garnet(Nd:YAG)laser posterior capsulotomy in pseudophakic eyes. Methods A total of 33 outpatients(38 eyes)of the Eye Hospital of China Medical University were recruited for the study,and the including criteria were as follow:best corrected visual acuity ≥ 0.6,without any other eye diseases,eye surgery history,ocular trauma history,corneal contact lens wearing. The PCO should not be too severe for iTrace visual function analyzer to make accurate measurement for the patients. Wavefront aberrations in the patients were measured and analyzed before and after Nd:YAG laser posterior capsulotomy. The size of laser capsulotomy was 5.0 mm. Results There was no significant difference in best corrected visual acuity,the IOP and the flare of aqueous humor in all eyes one hour after Nd:YAG capsulotomy(P > 0.05). The sphere refraction and the total aberrations,total higher-order aberrations(3.0 mm and 5.0 mm pupil size )in all eyes were significantly decreased after capsulotomy(P < 0.05). No retinal detachment,cystoid macular edema and dislocation of IOL were observed during the 3-month follow up. Conclusion Wavefront aberrations can represent the visual function of PCO sensitively,which can be regarded as evaluating criterion for performing Nd:YAG laser posterior capsulotomy.

Key words: wavefront aberrations, Nd:YAG, cataract, pseudophakic eye, posterior capsule opacification
