Purpose To evaluate the long-term outcomes of ciliary sulcus versus capsular bag fixation intraocular lenses (IOLs) in children after pediatric cataract surgery. Methods IOL was implanted 21 eyes 14 children, and 19 12 for treatment an institutional setting. Ultrasound biomicroscopy (UBM) performed. Main outcome measures included decentration, tilt, anterior chamber depth (ACD), angle-opening distance at 500 μm (AOD500), trabecular-iris angle (TIA), best-corrected visual acuity (BCVA), pressure (IOP), incidence postoperative complications. Results The mean follow-up period 6.81 ± 1.82 years. Comparing to group, group had higher vertical horizontal tilt (p = 0.02, 0.01,0.01, respectively), iris-IOL contact peripheral synechia 0.001, 0.03, smaller ACD, AOD500, TIA 0.04, IOP (17.10 ±6.06 mmHg vs.14.15± 4.74 mmHg, p 0.01), secondary glaucoma (28.57% vs. 10.53%, 0.007).There no significant difference between two groups with regard BCVA, refractive errors, myopic shift, nystagmus, strabismus, axis opacity. Conclusions Ciliary IOLs may increase malposition crowding segment, associate a risk compared IOLs.
