Comparisons of the in-the-bag stabilities of single-piece and three-piece intraocular lenses for age-related cataract patients: a randomized controlled trial.

ABSTRACT: To compare the in-the-bag stability and visual function of single-piece intraocular lenses (IOLs) and three-piece IOLs.A total of 65 patients with age-related cataracts (80 eyes) were enrolled and randomly assigned to receive in-the-bag implantation of either a single-piece IOL (40 eyes) or a three-piece IOL (40 eyes). Follow-up visits were conducted at 1 week, 1 month and 3 months postoperatively. Visual acuity, refraction and total aberration were examined. IOL position stability (including axial movement, decentration and tilt) was measured using a Scheimpflug imaging system.At the 3-month follow-up visit, single-piece IOLs did not exhibit significant axial movement (0.07?±?0.30 mm, p?=?0.13) compared with their axial position at 1 week postoperatively, whereas three-piece IOLs displayed forward axial movement of -0.22?±?0.23 mm (p?
