Anterior Chamber Depth (Acd) And Lens Thickness (Lt) As Predictors Of Intraocular Lens (Iol) Position After Cataract Surgery

To evaluate the association between preoperative ACD, lens thickness, tilting and decentration with postoperative ACD following cataract surgery

Eye Clinic, ASST Franciacorta, Chiari (BS)

In this retrospective observational study, we recruited 50 eyes of 45 patients who underwent cataract surgery at our clinic between June 2023 and January 2024. Axial length and intraocular lens (IOL) power calculation were obtained using optical biometer (OA2000) whereas Fourier-domain optic coherence tomography (CASIA2) was used for collecting anterior chamber depth, lens thickness and tilting. 

The AL and the preoperative ACD were positively correlated with postoperative ACD (r²= 0,47 p<0.01 and r²=0,585 p<0.01 respectively). There was a significant negative relationship between LT and postoperative ACD (r²= 0,1705, P=0.03), whereas lens tilting and decentration did not show a correlation.

The postoperative modification of the ACD has shown to be related to the preoperative ACD, AL and LT. The regression formula of the postoperative ACD could be used to predict the effective IOL position and consequent refractive error in the clinic.
