Objective To assess the difference, correlation and agreement of the biometry parameters measured by Pentacam and IOLmaster700 in cataract patients. Methods A. 84 cataract surgery candidates(155 eyes) were enrolled in Weifang Eye Hospital from March, 2018 to November, 2019 and analyzed from a prospective cohort study. There were 38 males(69 eyes)and 46 females(86 eyes)with the mean age of(59.7±10.5) years-old(ranging from 3 to 81 years-old). Keratometry values at the flat(K1) and steep(K2) axis, mean corneal power(Km) and magnitude of corneal astigmatism(△K) and anterior chamber depth from anterior corneal surface to anterior lens surface(ACD), anterior chamber depth from posterior corneal surface to anterior lens surface(AQD), and central corneal thickness(CCT) were examined by IOLMaster 700 and Pentacam. Pentacam takes two range values of simk(15°), simk(2.5 mm). The difference, correlation and consistency of the measurement results of IOLmaster700, simk(15 °) and simk(2.5 mm) were expressed as x^(-)±s after normality testing and analyzed by t-test of paired samples and Bland-Altman. Results The K1 values measured by IOLMaster700 and Pentacam simk(15 °) and simk(2.5 mm) were(43.41±1.59)D,(43.46±1.61)D,(43.44±1.61)D, respectively;and the K2 values were(44.24±1.71)D,(44.25±1.72)D,(44.28±1.72)D, km values(43.82±1.61)D,(43.85±1.64)D,(43.86±1.63)D, respectively;and △K values were(0.83±0.68) D,(0.80±0.63) D and(0.84±0.64) D, respectively. ACD values measured by IOLMaster700 and Pentacam(Ext) were(3.11±0.48)mm,(3.17±0.46)mm, respectively;and AQD values measured by IOLMaster700 and Pentacam(Int) were(2.58±0.48) mm,(2.64±0.46)mm;the mean CCT values were(529.39±25.91) μm,(530.35±25.21) μm, respectively. There was no significant difference in ACD(Ext), ACD(Int) and CCT between two instruments(t=-1.555,-1.506,-0.385;P>0.05). There was no significant difference in K1, K2, Km, △K between IOLmaster700 and Pentacam simk(15°)(t=-1.955,-0.223,-1.480,-0.953;P>0.05). There was no significant differe
