Accuracy of qualitative prediction in cataract surgery by double-pass optical quality analysis system

摘要:

目的：评价双通道视觉质量分析系统(OQAS^TMⅡ)定性预测白内障手术效果的准确性。

方法：回顾性研究。选取2018-10/12于我院行手术治疗的白内障患者57例67眼，根据术前客观散射指数(OSI)分为A组(28眼，OSI>8.0)、B组(28眼，OSI≤8.0)、C组(11眼，因晶状体严重混浊无法检测出OSI值)。根据术前模拟对比度视力(Predicted VA100%)和术前最佳矫正视力(BCVA)预测手术疗效。

结果：A组患者术后达到符合标准者26眼(93%)，B组患者术后达到符合标准者24眼(86%)，两组患者术后符合率无差异(P=0.669)，且两组患者术前Predicted VA100%与术后2wk BCVA无相关性(r_s=0.103，P>0.5)。

结论：OQAS^TMⅡ系统能够客观、准确、直观地定性预测白内障手术疗效。

Abstract:

AIM: To evaluate the accuracy of qualitative prediction of cataract surgery by double-pass optical quality analysis system(OQAS^TMⅡ).

METHODS: A retrospective study was conducted. Totally 57 cataract patients(67 eyes)were randomly selected from October 2018 to December 2018 in Renmin Hospital of Wuhan University. According to the objective scattering index(OSI), they were divided into group A(28 eyes, OSI>8.0), group B(28 eyes, OSI≤8.0), and group C(11 eyes, OSI could not be detected due to severe lens opacity). The effect of surgery was predicted by Predicted VA100% and preoperative BCVA.

RESULTS: In group A, 26 eyes(93%)comply with the standard, and in group B, 24 eyes(86%)comply with the standard. There was no significant difference between the two groups(P=0.669). Besides, no correlation was found between Predicted VA100% and postoperative 2wk BCVA(r_s=0.103, P>0.5).

CONCLUSION: The OQAS^TMⅡ system can objectively, accurately and intuitively predict the effect of cataract surgery.
