Lenstar LS900临床应用的研究进展

Research Progress in Clinical Application of Lenstar LS900

准确眼生物测量为眼科疾病诊治提供有力依据。各种眼生物测量仪不断改进更新,从超声原理发展到部分相关干涉原理,准确性明显提高,但仍有局限性。近年上市的新型眼生物测量仪—Lenstar LS900,基于低相干光反射原理设计,具有易用、准确性高、重复性好和一次测量可获得多个眼生物参数且不需重新调整视轴等特点,具有广泛的应用前景。该文就Lenstar LS900测量仪原理、临床应用进展进行综述。

Accurate ocular biometry provides powerful basis for the diagnosis and treatment of ophthalmic diseases. A variety of ocular biometry devices have constantly improved and updated, developing from ultra- sonic principle to partial coherence interferometry principle. The accuracy has been improved obviously, though there are still limitations. Recently a new type of ocular biometry device-Lenstar LS900 is commercially available,based on low coherence reflectometry principle, featured with easy operation, high accuracy, good repeatability ;which can obtain many ocular parameters in once measurement without realignment, thus is expected to have wide application prospects. Here is to make a review of the principle and clinical application of the Lenstar LS900.
