Decentration and Tilt of Intraocular Lens after Posterior Capsulotomy.

PCO is associated with not only axial displacement, but also tilt and decentration of IOL at the vertical and horizontal meridians. Laser capsulotomy decreased IOL tilt but had no effect on decentration. However, these changes did not significantly change the visual acuity between the control group and the PCO group after capsulotomy.
