AIM:To compare the difference, correlation and consistency of corneal biological parameters measured by IOL Master 700 and Pentacam before cataract extraction and intraocular lens implantation in different age groups.METHODS: Cross-sectional study. A total of 87 cataract patients(162 eyes)in Weifang Eye Hospital from February to September 2020 were collected, including 44 males(80 eyes)and 43 females(82 eyes)(age 61.2±9.87 years). The patients were divided into four groups: group A [17 cases(32 eyes), 40-50 years old], group B [25 cases(47 eyes), 51-60 years old], group C [28 cases(53 eyes), 61-70 years old], and group D [17 cases(30 eyes), 71-80 years old]. The preoperative corneal biological parameters of cataract patients were measured by IOL Master 700 and Pentacam, and the flat axis corneal curvature(K1), steep axis corneal curvature(K2), mean corneal curvature(Km), corneal astigmatism, anterior chamber depth(ACD)and central corneal thickness(CCT)were recorded. The difference and correlation of measurement results between two kinds of biometric instruments in different age groups were analyzed. RESULTS: Except for the corneal astigmatism in group C and K1 and corneal astigmatism in group D, there were significant differences between the two instruments(t=2.746, -2.582, 2.637, all P |
