영문 초록

Purpose: To investigate clinical availability of AL-ScanTM (Nidek, Gamagori, Japan) by comparing corneal refractive power with AL-ScanTM, AutokeratometerTM (Topcon KR-1, Tokyo, Japan) and PentacamTM (Oculus, Wetzlar, Germany) devices. Methods: Seventy-one patients (142 eyes) who visited our hospital for refractive surgery were tested using AL-Scan^{Ⓡ, Autokeratometer and PentacamⓇ and corneal refractive power was compared among devices. Results: When comparing measurements with AL-ScanⓇ, Autokeratometer and PentacamⓇ, the mean corneal refractive power was 43.37 ± 1.32 D (2.4 mm zone), 43.35 ± 1.32 D (3.3 mm zone), 43.36 ± 1.35 D, and 43.35 ± 1.36 D respectively and showed no significant differences. Corneal refractive power had strongly positive linear correlation (p < 0.001) and Bland-Altman plots showed high degree of agreement among AL-ScanⓇ, Autokeratometer and PentacamⓇ devices. Conclusions: Because measuring ocular biometry with AL-ScanⓇ including axial length, intraocular lens power calculation and topography simultaneously is possible, clinical use is convenient. Corneal refractive power was not different when compared with autokeratometer and PentacamⓇ, thus, AL-ScanⓇ can be used in the clinical environment. J Korean Ophthalmol Soc 2014;55(7):984-990}
