目的评价A超声速调整法测量硅油填充并发白内障患者眼轴长的可行性和准确性。方法由同一经验丰富医师应用A超声速调整法坐位测量15例(15眼)硅油填充并发白内障患者术眼的眼轴长,并计算人工晶状体度数,由同一操作熟练医师对患者施行玻璃体腔硅油取出联合白内障超声乳化吸出及人工晶体植入术。术后应用自动验光仪测量术眼的屈光状态,计算平均绝对屈光误差值;并应用常规A超测量法再次测量术眼的眼轴长,与术前测量结果进行比较。结果 A超声速调整法计算人工晶体度数的平均绝对屈光误差值为(0.711±0.196)D;15例病人术前A超声速调整法测量平均眼轴长(23.85±0.78)mm,术后常规A超法测量平均眼轴长(23.72±0.86)mm,二者之间的差异无统计学意义(P>0.05)。结论 A超声速调整法测量硅油填充并发白内障患者眼轴长准确、可行,可在临床上推广应用。 Objective To evaluate the feasibility and accuracy of A supersonic adjustment method in measuring axial length of patients with silicone oil-filled cataract. Methods The same experienced physician using A supersonic adjustment method to measure the axial length of the 15 eyes (15 eyes) of patients with cataract and filled with silicone oil and calculate the degree of intraocular lens, by the same operation of the physician on patients with vitreous silicone oil extraction combined Cataract phacoemulsification and intraocular lens implantation. The refractive status of the ophthalmoscope was measured with automatic refractometer and the mean absolute refractive error was calculated. The ocular axial length of the ophthalmoscope was measured again by conventional A-ultrasound and compared with preoperative measurements. Results The mean absolute axial error was (0.711 ± 0.196) D. The average axial length (23.85 ± 0.78) mm was measured in 15 patients before surgery by A supersonic adjustment. The average postoperative A-ultrasound The mean axial length measured by the method was (23.72 ± 0.86) mm, with no significant difference between them (P> 0.05). Conclusion A supersonic adjustment method for measuring the axial length of patients with silicone oil-filled cataract patients is accurate and feasible, which can be widely applied in clinic.
