Abstract

Abstract: : Purpose: Measurement of anterior chamber (AC) width with optical coherence tomography (OCT). Methods: A high-speed, wide-field 1.3 micron wavelength OCT system was developed. OCT AC scans were made on 40 normal eyes (20 subjects). White-to-white corneal diameter was measured with a corneal ruler. Results: AC width averaged 12.5 mm (±0.47 mm SD, 11.5 to 13.5 range) and reproducibility was 0.11 mm. AC width-corneal diameter difference averaged 0.75 mm (±0.44 mm SD, range - 0.31 to + 1.84 mm). Conclusions: AC width is not accurately predicted by external corneal diameter. OCT can precisely measure AC dimension to improve AC-IOL sizing.
