This study was performed to observe the potential refractive prediction error based on alternative A-scan ultrasound and fellow-eye biometry for phacovitrectomy in macula-off rhegmatogenous retinal detachment (RRD) eyes.
Phakic macula-off RRD eyes without axial length (AL) measurements obtained using IOLMaster were included. Vitrectomy without lens extraction was performed for RRD repair. Preoperative AL was measured using alternative A-scan ultrasound (AL-US). Postoperative AL was obtained in eyes with silicone oil tamponade (AL-SO) and preoperative fellow-eye biometry (AL-FE) using IOLMaster. Other eyes that faced the same preoperative situation but underwent phacovitrectomy based on fellow-eye biometry were recruited as controls.
AL-US, AL-FE, and AL-SO were 25.39 ± 2.14 mm, 25.85 ± 2.16 mm and 26.08 ± 2.53 mm, respectively. The Bland-Altman agreement among AL-US, AL-FE and AL-SO was good (95.5%, 21/22 of cases were in the LoA). The mean IOL power calculated using AL-US (Power-US), AL-FE (Power-FE) and AL-SO (Power-SO) was 16.81 ± 7.19 D, 14.74 ± 6.95 D and 13.54 ± 8.32 D, respectively. The difference between AL-US and AL-SO was significant (P < 0.05), while that between AL-FE and AL-SO was not (P > 0.05). The difference between Power-US and Power-SO was significant (P < 0.05), while that between Power-FE and Power-SO was not (P > 0.05). Nine eyes underwent phacovitrectomy based on fellow-eye biometry and had a final postoperative myopic shift of 0.64 ± 0.78 D.
Alternative A-scan ultrasound led to a significant difference in AL and a prediction error in IOL power, while fellow-eye biometry provided similar results to silicone oil-filled eyes after RRD repair.
本研究旨在观察基于替代A超超声测量以及健眼生物测量法预测黄斑脱离性孔源性视网膜脱离（RRD）眼行晶状体玻璃体切除术时潜在的屈光预测误差。
纳入未使用IOLMaster测量眼轴长度（AL）的有晶状体黄斑脱离性RRD眼。行玻璃体切除术修复RRD，术中不摘除晶状体。术前使用替代A超超声测量AL（AL-US）。对硅油填充眼，术后测量AL（AL-SO），并使用IOLMaster测量术前健眼生物参数（AL-FE）。将其他术前情况相同但基于健眼生物测量法行晶状体玻璃体切除术的眼作为对照。
AL-US、AL-FE和AL-SO分别为25.39±2.14mm、25.85±2.16mm和26.08±2.53mm。AL-US、AL-FE和AL-SO之间的Bland-Altman一致性良好（95.5%，22例中有21例在一致性界限内）。使用AL-US（Power-US）、AL-FE（Power-FE）和AL-SO（Power-SO）计算的平均人工晶状体度数分别为16.81±7.19D、14.74±6.95D和13.54±8.32D。AL-US与AL-SO之间差异有统计学意义（P<0.05），而AL-FE与AL-SO之间差异无统计学意义（P>0.05）。Power-US与Power-SO之间差异有统计学意义（P<0.05），而Power-FE与Power-SO之间差异无统计学意义（P>0.05）。9只眼基于健眼生物测量法行晶状体玻璃体切除术，术后最终近视漂移为0.64±0.78D。
替代A超超声测量导致AL有显著差异及人工晶状体度数预测误差，而健眼生物测量法在RRD修复术后提供的结果与硅油填充眼相似。
