摘要
目的分析高度近视晶状体性手术前晶状体透明程度、眼底状况与术后视网膜脱离发生的关系,探讨手术效果、安全性与手术选择的时机。方法根据高度近视晶状体性手术前情况将患者分成晶状体非透明组52眼和较透明组200眼,透明组内还分眼底无或有轻度病变组,后者相应进行激光治疗,随访分析这些患者手术前后视力与眼底改变。结果高度近视性晶状体手术术后患者视力均得到显著改善,晶状体较透明组视力恢复>0.5的占77.5%;晶状体较透明组视力恢复较非透明组,t=8.393,P=0.000,改善更加明显;仅非透明组发生3例视网膜脱离,相对较透明组,χ2=15.520,P=0.000,有显著差别,术前有眼底病变的较透明组经术前干预也未发生脱离;手术其他并发症少且轻微。结论高度近视患者应争取在晶状体非透明期前手术,可以更好的提高手术后视力,减少视网膜脱离的发生率,并使手术前进行干预成为可能。
AIM: To observe the effect, safety and timing of refractive surgery in high myopic patients by analyzing the sight improvement and incidence of retinal detachment.· METHODS: Patients were divided according to their lens status into Opaque Group (52 eyes) and Transparent Group (200 eyes). They were both given refractive surgery and the latter underwent further laser management. Their postoperative visual acuity and retina changes were followed up.· RESULTS: All patients' visual acuity improved markedly. Those of 77% patients' increased to above 0.5 in Transparent Group, which were much more significant compared with Opaque Group (t =8.393, P =0.000). There was no retinal detachment in Transparent Group, even with slight retinal degeneration, which was lower than that in Opaque Group (χ 2=15.520, P= 0.000).· CONCLUSION: Refractive surgery should be performed at the transparent stage of lens, which may lead to better sight improvement, lower retinal detachment risk and the possibility of pre-operative treatment for retinal changes.·
