Abstract Details

Purpose:

To describe the distribution of ocular biological parameters and their relationship with age.

Setting:

Their axial length, anterior chamber depth, corneal curvature and other biological structural parameters of eye structures were measured by IOL master, respectively, and the distribution characteristics of these parameters and their relationship with age were discussed.

Methods:

Using multicenter retrospective analysis of clinical research, from July 2013 to December 2018, collected in the EYE eye corp. 's distribution in all parts of the country's 18 EYE eye hospital, 2038733 cases of cataract patients, the 143889 eyes of 143889 patients included in the study, patients were greater than the age of 40, a grouping per 10 years old, all can be divided into six age groups.

Results:

This study evaluated 143889 eyes with an average axial length (AL) and anterior chamber depth (ACD) of 23.92±2.14mm and 3.04±0.45mm, respectively, and an average corneal astigmatism of 1.05±0.90d, among which 38.9% had astigmatism greater than 1.0d. The mean axial length and anterior chamber depth decreased with age (P<0.001).

Conclusions:

Ocular biological characteristics data and corneal astigmatism can help ophthalmologists to improve the operation and select appropriate intraocular lens to obtain high quality postoperative vision.
