Description
<p> 【Purpose】We examined the differences in corneal power of table-mounted and handheld keratometers with different light configurations.</p><p> 【Methods】Corneal power was measured from the right eyes of 189 university students (aged 20.2±1.2 years) with no eye disease other than refractive error using four types of auto-keratometers and analyzed using power vector analysis.</p><p> 【Results】The mean corneal power was 43.37 for TONOREF II, 43.40 for ACOMOREF 2, 43.38 for Retinomax K+Screeen (RMS), and 43.49 [D] for Retinomax K-plus3 (RM3), with RM3 having a significantly higher value (p<0.001). J0 was significantly positive for RM3 (p<0.001), and J45 was significantly different in each group (p=0.002 to <0.001), except between ACOMOREF2 and RM3.</p><p> 【Conclusion】Although there were significantly different in corneal power in keratometer models, these differences were not clinically relevant (<0.25 D).</p>
