The objective of this study is to compare biometric measures across diverse populations with varying ethnicity, gender, age, and environmental conditions. While numerous articles have explored biometric normality in different populations, none have specifically compared biometric normality between Africans and Europeans. This is important because those parameters can affect the calculation of the appropriate intraocular lens to be implanted, and because many of the formulas used for this calculation are based on standardized biometry.

The study sample consisted of individuals of both genders and ethnicities, aged 18 years and above. Individuals with ocular pathologies that impair ocular media transparency or alter the anterior surface (such as ectasia), those of mixed ethnicity, and those who had undergone previous refractive surgery were excluded. Various parameters, including subjective refraction, axial length, corneal diameter, and anterior chamber depth, were assessed. Additionally, the study included the evaluation of patients' quality of life using a validated questionnaire.
The primary variable under investigation, axial length, yielded the following results: the Caucasian group exhibited a mean axial length of 24.37 ± 1.3 mm in the right eye (RE) and 24.29 ± 1.3 mm in the left eye (LE); the Afro-European group demonstrated a mean axial length of 24.23 ± 0.6 mm RE and 24.30 ± 1.1 mm LE; and finally, the African group displayed a mean axial length of 22.91 ± 0.5 mm RE and 22.89 ± 0.5 mm LE.
In summary, there is a significant variation in ocular biometry among the study groups. Specifically, we note a marked difference between the African and European groups, while the African-European group bears a resemblance to the European group. However, due to the current sample size, further investigation with a larger sample is necessary to draw definitive conclusions
