Early dynamics of intraocular lens position: longitudinal analysis of decentration and tilt after surgery

Year: 2026
Type: article
Study design: Observational Study
Abstract: AIMS: To analyze the early dynamics of intraocular lens(IOLs) tilt and decentration within the first postoperative month and associated risk factors. METHODS: This study included patients who underwent conventional phacoemulsification with IOL implantation. All patients underwent preoperative ophthalmic examinations. The tilt and decentration of IOLs were measured by the second-generation anterior segment optical coherence tomography (Casia2). Univariate and multivariate regression analyses were used to evaluate the relationship between tilt and decentration of IOLs and ocular biometric parameters(defined as tilt ≥ 7°and decentration ≥ 0.4 mm). RESULTS: A total of 192 patients (192 eyes) were included. 1 day, 1 week, and 1 month after the cataract surgery, there was no statistically significant difference in the tilt and decentration of IOLs (4.82 ± 2.08°vs4.91 ± 2.10°vs4.85 ± 2.08°and 0.23 ± 0.12mmvs0.22 ± 0.13mmvs0.23 ± 0.14 mm, all p > 0.05). Crystalline lens tilt(odds ratio [OR] = 2.08), age (OR = 1.07), Lens vault(LV)(OR = 4.52), lens thickness (LT) (OR = 3.48), anterior chamber depth (ACD) (OR = 0.17), white-to-white(WTW)(OR = 0.63) and anterior chamber width(ACW) (OR = 0.23) were associated with IOLs tilt exceeding 7 degrees (all P < 0.05). Crystalline lens tilt is an independent risk factor for clinically significant IOLs tilt. CONCLUSIONS: The IOLs demonstrated outstanding early stability within the capsule. The IOLs tilt magnitude was greater in patients with a larger age, crystalline lens tilt, LV, LT, and smaller ACD, WTW, and ACW. In these patients, premium IOLs should be implanted cautiously.
