【摘要】：目的探討一種最新的光學(xué)低相干反射測量儀Lenstar LS 900對于眼球生物測量的準(zhǔn)確性,將其測量值與光學(xué)相干生物測量儀IOLMaster的測量結(jié)果進(jìn)行比較。方法對照觀察分別由Lenstar LS 900和IOLMaster測量的正常人群眼球的眼軸長度(axial length,AL)、前房深度(anterior chamber depth,ACD)、角膜子午線上下的曲率半徑(CR1、CR2)和白對白角膜直徑(white-to-white distance,WTW)等眼球生物學(xué)參數(shù)。結(jié)果本研究納入了206個健康的成年個體(206眼),年齡(26.9±15.6)歲。兩種測量儀對于AL、ACD、CR1、CR2和WTW等測量值的相關(guān)程度很高。Lenstar LS 900與IOLMaster的測量結(jié)果比較,AL差值(0.014±0.090)mm(P=0.025),CR1差值(0.006±0.030)mm(P=0.005),CR2差值(0.020±0.040)mm(P0.001),均略長;WTW較短差值(-0.110±0.400)mm(P0.001),ACD的差異無統(tǒng)計學(xué)意義(P=0.554)。除WTW一致性界限為-0.89~0.67 mm外,兩種測量儀的測量數(shù)據(jù)具有良好的一致性。結(jié)論與IOLMaster相比較,Lenstar LS 900可提供同樣準(zhǔn)確、可靠的眼球生物測量數(shù)據(jù)(除WTW外),并且可提供中央角膜厚度和晶狀體厚度數(shù)據(jù),因此Lenstar LS 900在屈光手術(shù)和白內(nèi)障手術(shù)領(lǐng)域有很好的應(yīng)用前景,能滿足未來高質(zhì)量白內(nèi)障手術(shù)的要求。
[Abstract]:Objective to investigate the accuracy of a new optical low coherence reflection measuring instrument (Lenstar LS 900) for eyeball bioassay, and to compare its measured value with that of optical coherent biometric instrument (IOLMaster). Methods the axial length (axial length,AL), anterior chamber depth (anterior chamber depth,ACD) and curvature radius (CR1,) of the upper and lower meridians of the cornea were measured by Lenstar LS 900 and IOLMaster, respectively. The biological parameters of eyeball, such as CR2) and white to white corneal diameter (white-to-white distance,WTW). Results 206 healthy adult individuals (206 eyes), aged (26.9 鹵15.6) years, were included in this study. The correlation between the two measuring instruments for AL,ACD,CR1,CR2 and WTW is very high. Compared with IOLMaster, AL difference (0.014 鹵0.090) mm (P 鈮，
