ABSTRACT
To compare the measurements of axial length by A-scan ultrasound and IOLMaster.For a total of 138 eyes,axial length was measured with IOLMaster followed by contact A-scan ultrasound.Though a great correlation existed between two measurements,the axial length was a little longer with IOLMaster than with A-scan ultrasound.And the difference was statistically significant (P < 0.01).The mean difference of two methods was (-0.198 ± 0.146) mm.With the elongation of axial length,the difference of two methods also increased.For cataract patients with axial length > 28 mm,the control range of crror from IOLMaster for axial length was much lower than that from A-scan.Thus IOLMaster is a simple,fast,reliable and non-contact measurement method of axial length.
