Eye Biometric Analysis Of Cataract Patients Over 40 Years Old In Suzhou, China

In this study, cataract patients over 40 years old in Suzhou, China were selected to describe the distribution characteristics of ocular biological parameters and perform a number of statistical analyses, so as to provide certain reference for the diagnosis and treatment of refractive cataract.

Cataract is the leading cause of blindness in the world and China, and the incidence increases with age. As an aging city, Suzhou has a heavy burden of cataract among people over 40 years old. The study of eye biometrics in this population is of great significance in the following aspects.

Patients who received cataract surgery in Ideal Eye Hospital of Soochow University from January 2019 to September 2022 were selected. Intraocular pressure, diopter, axial length, anterior chamber depth, intraocular lens degree corneal curvature K1, corneal curvature K2, and corneal astigmatism were measured in all patients. SPSS22.0 software was used and α=0.05 was used as the test level

A study of 3373 cataract patients showed that axial length (AL) and anterior chamber depth (ACD) of female eyes were smaller than those of male eyes, and corneal curvature K1 and K2 were larger than those of male eyes. The proportion of female astigmatism is higher than that of male, and the proportion of inverse astigmatism is lower than that of male. Age was negatively correlated with AL, ACD and IOP, but positively correlated with K1 and K2. Corneal astigmatism decreased and then increased with age. Correlation analysis showed that AL was positively correlated with ACD and negatively correlated with corneal curvature.

This study focuses on the age and sex differences of various biological parameters and their correlation, so as to provide reference for cataract surgery.
