영문 초록

Purpose: To investigate the accuracy of biometry and intraocular lens (IOL) power calculation using partial coherence interferometry (IOL Master®) in highly myopic patients with axial lengths of 26 mm or greater. Methods: Patients with axial lengths equal to or greater than 26 mm who had undergone cataract surgery were enrolled. IOL power was calculated using IOL Master and/or applanation ultrasonography with the SRK/T formula. Twenty-seven eyes using both IOL Master and applanation ultrasonography were included in a paired group, and forty-eight eyes using the IOL Master only and twenty-five eyes using applanation ultrasonography only were included in unpaired groups. The differences between the predicted refraction and the actual refraction were compared and analyzed. Results: In the paired study, the axial lengths in patients using IOL Master (29.14±2.32 mm) were significantly longer than those of patients using applanation ultrasonography (28.57±2.23 mm) (p<0.05). The mean absolute error (MAE) of the IOL Master and applanation ultrasonography groups were 0.62±0.58D and 0.87±0.49D, respectively (p>0.05). In the unpaired study, the MAEs of the IOL Master and applanation ultrasonography groups were 0.61±0.61D and 0.65±0.63D, respectively. Conclusions: In eyes with axial lengths of 26.0 mm or greater, the accuracy of IOL power calculation with IOL Master using the SRK/T formula was comparable to that with applanation ultrasonography.
