Background: Several studies have shown the correlation between ocular biometry with refractive errors. Since these parameters can be influenced by race, ethnicity, and genetics, their differences between different populations can probably explain the differences in refractive errors. We present the biometric values measured in 431 eyes with normal, short, long, and extremely long axial length (AL) from the Latin American population. Patients and Methods: All eye measurements were performed using optical biometry with IOL Master and stratified according to AL and anterior chamber depth (ACD) and evaluated in relation to each other. Symmetry between right eye (RE) and left eye (LE) was also analyzed. Setting: The study was conducted at Private practice, Guadalajara, Jalisco, Mexico. Results: ACD, white-to-white (WTW), and average keratometries (K) increase as AL increases in normal, short, and long eyes, but this correlation is not maintained in extremely long eyes. Most of the short eyes and eyes with normal AL have a normal ACD, but most of the long and extremely long eyes have an ACD >2.5 mm. In normal and short eyes, the AL and WTW are symmetric in both eyes, but in long and extremely long eyes, there are significant differences between RE and LE. ACD is symmetric in RE and LE regardless of AL. Conclusions: The importance of the ocular biometry in Latin American eyes relies on clarifying the assumptions of biometric measurements commonly used in various areas of ophthalmology including intraocular lens calculation formulas.
