Abstract. Purpose:To compare the efficacy of optical axial length measuring device and contact A-scan ultrasonography(A-mode device)in cases undergoing phacotrabeculectomy. Subjects and Methods:This study included 64 eyes of 49 cases scheduled for phacotrabeculectomy. Using IOLMaster® and A-mode device, intraocular lens power was calculated according to the SRK/T formula. The measured refractive error(absolute value)obtained from both devices were compared 3 months after surgery. Results:Refractive error absolute values were 0.66±0.55D(range:0.02~2.46D)with the IOLMaster® and 0.80±0.62D(0.01-3.11D)with the A-mode device. There was no difference between the two(p=0.08). The subjects with refractive error under 0.5D was significantly larger in data obtained with IOLMaster®(IOLMaster®:55% vs A-mode device:33%, p=0.02). Conclusion:IOLMaster® was more precise than A-mode device in calculation of target intraocular lens power in phaco-trabeculectomy.
