Context Accurate intraocular lens (IOL) power calculation is mandatory to achieve satisfactory refractive outcomes. Axial length, keratometric readings, anterior chamber depth, and other measurements are utilized to estimate postoperative effective lens position. Selecting the formula of IOL calculation depends mainly on axial length (AL) and anterior chamber depth (ACD). Aims To study the correlation between AL and ACD in short, normal, and long eyes. Settings and design The study was conducted at Ain Shams University Hospitals after the approval of the research ethics committee in the Faculty of Medicine, Ain Shams University. Study period: 6 months. Patients and methods The study included 90 eyes of patients presented for IOL or phakic lens implantation. They were divided into three groups according to the AL. Group A included 30 patients with short AL of less than or equal to 22 mm. Group B included 30 patients with normal AL of more than 22 mm and less than 24.50 mm. Group C included 30 patients with long AL of more than or equal to 24.50 mm. The AL and ACD of each patient were measured using The ZEISS IOL Master 500. Statistical analysis used The Statistical Package for the Social Sciences, version 24. Results The results of our study showed that the correlation between the axial length and the anterior chamber depth among short eyes was statistically significant and they were negatively correlated, while no statistically significant correlation existed between AL and ACD in normal and long eyes. Conclusion The AL and ACD are inversely related in short eyes with an AL of less than or equal to 22 mm, while no correlation exists in normal and long eyes with an AL of more than 22 mm.
