Purpose
To study the correlation between AL and ACD in short, normal, and long eyes.
Methods
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, Cairo, Egypt. 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.
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 (p: 0.011), while no statistically significant correlation existed between AL and ACD in normal (p: 0.65) and long eyes (p:0.58).
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 affirming the importance of formulas that use the ACD depth in IOL calculation as Haigis, Holladay 2 and Barrett Universal Formula II in short eyes.
