目的 :比较A/B超测量眼轴长度的临床应用效果。方法 :应用A/B超测量了 72 9眼眼轴长度 ,并分别代入SRKⅡ公式 ,计算人工晶体 (IOL)度数。结果 :眼轴长度及IOL度数之差异均无显著性 (P >0 0 5 )。结论 :应用B超测量眼轴长度与A超有很好的一致性 ,能较好地为开展白内障摘除IOL植入术服务。
Objective: To compare the clinical effect of A / B over axial length measurement. Methods: The axial length of 729 eyes was measured by A / B ultrasonography. SRK Ⅱ formula was used to calculate the degree of intraocular lens (IOL). Results: There was no significant difference in axial length and IOL (P> 0.05). Conclusion: There is a good consistency between the axial length of A-ultrasound and B-mode ultrasonography, which can be a good service for cataract extraction and IOL implantation.
