Analysis on the accuracy of anterior segment measurement assessment system and optical biometer in predicting lens in ICL implantation
摘要
Abstract
Objective:To explore the accuracy of parameters of anterior segment measurement assessment system and optical biometer in predicting lens in implantable collamer lens(ICL)implantation.Methods:This study retrospectively analyzed the examination data of patients who underwent ICL surgery at the department of ophthalmology,Army Characteristic Medical Center from January 2020 to July 2024.The measured data of the chamber corner parameters,which included anterior chamber depth(ACD),central corneal thickness(CCT),white to white(WTW),flat keratometry(K1)and steep keratometry(K2),of 74 patients(134 eyes)who underwent simultaneous measurements of the IOLMaster 700 optical biometer and the Pentacam HR anterior segment measurement assessment system were selected.The expected spherical equivalent(EXP SPH),expected cylinder(EXP CYL),and expected spherical equivalent(EXP SEQ)were calculated,and the differences,correlations and consistencies of these data were analyzed.Results:There were significant differences in ACD,CCT,WTW,K1 and K2 between the IOLMaster 700 and Pentacam HR in measuring myopic patients(t=12.928,6.202,-37.877,-13.743,-12.007,P<0.001).All measured data showed high correlation(r=0.983,0.984,0.961,0.996,0.994,P<0.001).Bland-Altman consistency test showed that the measured values by 3%-6%were outside the limits of 95%consistency,and the differences among the EXP SPH of two instruments and the postoperative actually measured results of spherical lens(SPH),among the EXP CYL of two instruments and the postoperative actually measured results of cylinder lens(CYL),and among the EXP SEQ of two instruments and the postoperative actual measured results of spherical equivalent(SEQ)were statistically significant(x2=20.927,7.451,25.459,P<0.05).The average differences between Pentacam HR and IOLMaster 700 were respectively(0.024±0.491)D and(0.009±.491)D in predicting SPH,and were respectively(-0.05±0.476)D and(-0.049±0.475)D in predicting CYL,and were respectively(-0.001±0.458)D and(-0.016±0.461)D in predicting SEQ.Conclusion:During selection process of ICL surgery for lens,clinicians can reasonably choose Pentacam HR and IOLMaster 700 to calculate lens according to the actual requirements of the patients.关键词
