Abstract:
PURPOSE: To compare the axial lengths, anterior chamber depths, and keratometric measurements and to predict postoperative refractions of Dual Scheimpflug analyzer Galilei G6(R) and intra ocular lens (IOL) Master(R). METHODS: A total of 50 eyes in 50 patients who received cataract surgery were included in the present study. The axial length, anterior chamber depth, and keratometry were measured using 2 types of partial coherence interferometries (Galilei G6(R) and IOL Master(R)). The SRK/T formula was used to calculate IOL power and the predictive error which subtracts predictive refraction from postoperative refraction was compared between the ocular biometry devices. RESULTS: Axial lengths were 23.36 +/- 0.80 mm and 23.36 +/- 0.90 mm measured by Galilei G6(R) and IOL Master(R), respectively. Axial length measured by Galilei G6(R) was not statistically significant compared with IOL Master(R) (p = 0.321). The anterior chamber depth and keratometry were 3.22 +/- 0.35 mm and 44.29 +/- 1.40 D measured by Galilei G6(R) and 3.11 +/- 0.46 mm and 44.39 +/- 1.41 D measured by IOL Master(R), respectively. The differences of anterior chamber depth and keratometry between the 2 devices were statistically significant (p < 0.001 and p = 0.028, respectively). The mean absolute prediction errors were 0.45 +/- 0.37 D and 0.49 +/- 0.39 D in Galilei G6(R) and IOL Master(R), respectively and was not statistically significantly different (p = 0.423). CONCLUSIONS: The ocular biometric measurements and prediction of postoperative refraction using Galilei G6(R) were as accurate as with IOL Master(R).
