Purpose: To investigate the biological characteristics of the lens and explore the factors influencing the postoperative position of intraocular lens (IOL) using swept-source optical coherence tomography (SS-OCT) in cataract patients with long axial length (AL).Methods: This retrospective study enrolled 110 cataract patients who underwent uneventful cataract surgeries. The preoperative and postoperative biometric parameters were obtained using IOLMaster 700. The average lens density (ALD) was analyzed using Fiji ImageJ. The biological characteristics of cataracts were analyzed using 3-dimension (3D) parametric modelling software Pro/Engineer Wildfire 5.0.The lens equator position (LEP) showed positive correlation with the preoperative anterior chamber depth (ACD), LED (lens equatorial diameter) and LV (lens vaulting) . The postoperative position of the IOL showed positive correlation with the preoperative ACD and LEP (r = 0.432, P < .05; r = 0.657, P < .05). The LEP showed a higher correlation with the postoperative position of the IOL as compared with preoperative ACD (P < .05). The LEP displayed the highest correlation with the postoperative position of the IOL (r = 0.686, P < .05) in the subgroup of ultra-long eyes (AL ≥ 28.0 mm).The LEP based on the SS-OCT and 3D parametric modelling was the better predictor of postoperative IOL position compared with the preoperative ACD. This methodology provides a robust basis for accurately predicting the effective lens position in cataract patients with long AL.
