Objective: To compare the prediction accuracy of intraocular lens (IOL) formulas using partial coherenceinterferometry (IOLMaster) and applanation ultrasound (AL-3000) assisted corneal topography (TMS-4).Methods: Eyes (n=133) undergoing phacoemulsification cataract surgery with posterior chamber IOLimplantation in our hospital between January 15, 2016 and May 1, 2016 were studied proactively. Axial length(AL), K-value, and anterior chamber depth (ACD) were preoperatively measured using the IOLMaster, AL 3000, and TMS-4. Haigis, Hoffer Q, Holladay I, and SRK/T biometric formulas with optimized constants were used to calculate IOL power. Refractive outcomes were determined by streak retinoscopy and subjective manifest refraction 3 months after the surgeries. Formulas and biometers were evaluated by mean error, standard deviation (SD), range of error, mean absolute error, median absolute error, 95% confidence interval of mean absolute error,and percentage of eyes within ±0.5 diopter (D), ±1.0 D, and ±2.0 D of prediction. F-tests were used to comparethe results between formulas and biometers. Results: The SDs of the Haigis, Hoffer Q, Holladay I, and SRK/T formulas using IOLMaster were 0.468, 0.591, 0.613, and 0.624. The SDs of Hoffer Q, Holladay I, and SRK/T were significantly larger than that of Haigis (F=9.632, 11.984, 9.215, all P<0.05). SDs of the AL-3000 assisted with TMS-4 were 0.580, 0.624, 0.642, and 0.700, respectively. The SD of SRK/T was significantly larger than that of Haigis (F=5.365, P=0.021). In short eyes, the SD of SRK/T was significantly larger than that of Haigis (F=7.071, P=0.012) using IOLMaster. In long axis eyes, the SD of SRK/T was significantly larger than that of Haigis (F=6.681, P=0.012) using IOLMaster, with hyperopic shifts of 0.44 D and 0.43 D in Hoffer Q and Holladay I. Conclusions: The Haigis formula with measurements using the IOLMaster was promising in eyes with all ranges of AL.
