A prospective pilot study using a low power piggy-back toric implantable Collamer lens to correct residual refractive error after multifocal IOL implantation.

Purpose: To assess whether residual refractive error after in-the-bag multifocal intraocular lens (mIOL) implantation can efficaciously and safely be corrected with a piggy-back low power Visian Toric Implantable Collamer Lens (VTICL, STAAR Surgical) placed in the ciliary sulcus.

Patients And Methods: Twenty-four eyes of 23 patients (mean age: 57.5 years) with diminished uncorrected distance visual acuity (UDVA) of ≥2 lines due to residual refractive error after mIOL implantation were included in the study.

Influence of blurred vision, accommodation, and target laser settings on eye movements during LASIK.

Purpose: To analyze the influence of blurred vision, accommodation, and target laser settings on eye movements during laser in situ keratomileusis (LASIK).

Setting: Department of Ophthalmology, Goethe University, Frankfurt, Germany.

Design: Prospective randomized study.
