Anterior Segment Biometry in a Caucasian Population with Cataracts

Area of Science:

• Ophthalmology
• Biometry
• Anterior Segment Analysis

Background:

• Cataracts are a leading cause of vision impairment globally.
• Understanding the biometric parameters of the anterior segment is crucial for ophthalmic procedures.
• Age-related changes can significantly impact ocular structures.

Purpose of the Study:

• To investigate age- and sex-dependent biometric factors of the anterior segment in phakic eyes with cataracts.
• To analyze the relationship between anterior chamber depth and other biometric parameters.

Main Methods:

• A population-based study involving 6289 eyes from 3615 Caucasian patients with cataracts.
• Biometric parameters were measured using swept-source optical coherence tomography.
• Patients were grouped by age decade.

Main Results:

• Significant age-related decreases in anterior chamber depth and axial length were observed.
• Lens thickness increased with age.
• Axial length and anterior chamber depth showed significant differences between sexes.
• Anterior chamber depth correlated positively with white-to-white distance and axial length, and negatively with lens thickness.

Conclusions:

• Biometric parameters of the anterior segment exhibit age- and sex-dependent variations in cataract patients.
• Anterior chamber depth is influenced by white-to-white distance, axial length, keratometry, and lens thickness.
• These findings are important for refining intraocular lens calculation formulas.
