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 ±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 difference in K1, K2 and △K between IOLmaster700 and Pentacam simk (2.5 mm) (t=-1.037, -1.406, -0.324; P>0.05), but there was significant difference between Km (t=-2.002, P<0.05). Pearson correlation analysis showed that there was a good correlation in K1, K2, Km, △K between the results of two instruments (r=0.978, 0.979, 0.988, 0.751; P<0.05). The results of Bland-Altman analysis showed that the average value and 95%LoA range of the difference of ACD (Ext), ACD (Int) and CCT between IOLMaster700 and Pentacam were -0.06 (-1.06—-0.94)mm, -0.06 (-1.06—-0.94)mm and -1.0 (-61.4—-59.5)μm, respectively. The average value and 95%LoA range of the difference of K1, K2, Km, Km, △K between IOLMaster700 and Pentacam simk (15 °) and simk (2.5 mm) were -0.05 (-0.69—-0.59)D, -0.02 (-0.68—-0.62)D, -0.01 (-0.72—-0.71)D, -0.04 (-0.73—-0.65) D, -0.03 (-0.53—-0.47)D, -0.04 (-0.53—-0.45)D, 0.03 (-0.90—-0.83)D and -0.01 (-0.93—-0.90)D, respectively.

Conclusions

IOLMaster700 and Pentacam have good consistency in measuring the parameters of ACD and CCT for cataract patients. The corneal curvature value from pentacam simk (15 °) is closer to IOLmaster700, and the average Km of pentacam simk (2.5 mm) is significantly different from that of IOLmaster700.
