Abstract

Abstract : Pseudophakia ACD and IOL movement and position vary depending on IOL architecture. Fellow-eye visual outcome comparison suggests differences in IOL axial movement do not directly affect postoperative IOL performance. Abstract : Purpose: To compare the dynamics of axial intraocular lens (IOL) position and stability in the capsular bag after fellow-eye implantation of a 1-piece C-loop and a 4-point haptic IOL. Setting: Hanusch Hospital, Vienna. Design: Prospective, comparative, randomized bilateral study. Methods: One hundred eyes of 50 patients were randomly implanted with a C-loop IOL (CT LUCIA 611P) in 1 eye and a 4-point haptic IOL (CT ASPHINA 409MP) in the other eye. Anterior chamber depth (ACD) was measured at 1 week (W1), 1 month (M1), and 4 to 6 months (M4-6) postoperatively using a swept-source optical coherence tomography device (IOLMaster 700). Uncorrected distance visual acuity (UDVA), corrected distance visual acuity, and subjective refraction outcomes were assessed at M4-6 postoperative follow-up. Results: Hundred eyes of 50 patient were included. Pseudophakia ACD values at W1, M1, and M4-6 timepoints were significantly different in eyes implanted with the C-loop IOL compared with the 4-point haptic IOL ( P < .001). The overall IOL shift was 0.25 ± 0.16 mm for the 4-point haptic IOL and 0.14 ± 0.09 mm for the C-loop IOL ( P < .001). The M4-6 mean monocular UDVA outcome for eyes with C-loop IOL was 0.06 ± 0.14 logarithm of the minimum angle of resolution (logMAR) and 0.03 ± 0.10 logMAR for the eyes with 4-point haptic IOL. M4-6 mean spherical equivalent was −0.32 ± 0.48 diopter (D) in the C-loop IOL group and −0.33 ± 0.42 D in the 4-point haptic IOL group. Conclusions: Statistically significant differences in IOL design results in different postoperative ACD values. No relevant or statistically significant differences were found in refraction or visual acuity between the groups.
