研究问题
It is utilized to determine the appropriate size of intraocular lenses 2224 (IOLs), including anterior chamber phakic lenses[4] , and to anticipate the correct size of the capsular tension ring (CTR)[5] .；This controversy arises from varying definitions of corneal diameter, as multiple reference points at the limbus are utilized to determine the horizontal diameter of the cornea.；It also sought to investigate the association between corneal diameter and refractive errors, alongside various ocular and non-ocular parameters, employing a population-based cross-sectional approach in Tehran’s elderly population.
方法
Sampling was performed via a multi-stage cluster random sampling technique.
核心结论
Moreover, advancing age is associated with increased corneal irregularity[46] , which could differentially affect diameter measurements depending on the instrument’s algorithmic approach.；The R2 values for the full and reduced multiple models were 29.6% and 29.4%, respectively, signifying that 29% of the variance in corneal diameter can be elucidated by the model variables.；Further research is necessary to ascertain the link between corneal width and educational attainment, as this result runs counter to our findings and cannot be interpreted[17] .；Although revealing cohort effects requires longitudinal data, however, based on the findings of these studies and the current study, it can be concluded that adults over the age of 18 have smaller corneal diameters than younger adults.
局限
Before interpreting the results, it should be noted that due to the cross-sectional study design, the observed associations cannot be interpreted causally; therefore, the results should be interpreted with caution.
对本项目的价值
观察性关联，仅用于假说生成，不可作因果：线粒体是衰老干预的共同下游效应器，可用于跨器官效应的统一读数。 ｜ 价值分 1.0/5（★☆☆☆☆）

本文属人体研究证据，但需注意：观察性或小样本干预的结论不等于已证实临床获益；效应量与长期安全性仍需更大规模、更长随访的试验验证。
