Introduction:
Non-acquired lens anomalies are rather rare diseases. However, they are a cause a significant visual impairment presenting at a young age and a major cause of amblyopia. Besides the ocular implications, these anomalies could be either isolated or associated with systemic disorders, thus warranting systemic evaluation once diagnosed.
Ectopialentis (EL) is one of those anomalies that usually presents bilateral. Microspherophakia (MSP) is another lens anomaly where zonular development is defective, similar to ectopialentis, causing a smaller and spherical crystalline lens and thus causing lenticular myopia. Other less common lens anomalies include lenticonus, lentiglobus and lens coloboma.
The biometric characteristics of the crystalline lens anomalies have always been a field of concern in research to provide a better understanding of the shape of eyes in such conditions and might aid in diagnosis as those conditions are rare but rather imperative to be recognized because of the sight threatening complications.


Aim:
The aim of this study was to report on the biometric characteristics of the anterior segment of children eyes with non-acquired abnormalities in the natural crystalline lens shape or position.
