Purpose: To evaluate the visual outcomes, efficacy, predictability, and short-term safety of implanting the Sulcoflex (Rayner Intraocular Lenses Ltd) intraocular lens (IOL) to correct residual pseudophakic errors.

Methods: Retrospective study of patients undergoing implantation of the Sulcoflex IOL. Uncorrected (UDVA) and corrected (CDVA) distance visual acuity and refractive outcomes were evaluated.

Purpose: To determine whether the use of prophylactic intracameral cefuroxime during phacoemulsification cataract surgery is associated with increased macular thickening in the postoperative period.

Setting: Hull and East Yorkshire Eye Hospital, Hull, United Kingdom.

Methods: In this prospective randomized double-masked clinical study, the study group received 1 mg of intracameral cefuroxime and the control group received intracameral balanced salt solution only.

Purpose: To determine whether Hartmann-Shack wavefront sensing detects differences in optical performance in vivo between poly(methyl methacrylate) (PMMA) and foldable acrylic intraocular lenses (IOLs) and between clear corneal and scleral tunnel incisions and whether optical differences are manifested as differences in visual performance.

Setting: Department of Optometry, University of Bradford, West Yorkshire, United Kingdom.

Methods: This study comprised 74 subjects; 17 were phakic with no ocular pathology, 20 had implantation of a Pharmacia 722C PMMA IOL through a scleral tunnel, 21 had implantation of an Alcon AcrySof IOL through a scleral tunnel, and 16 had implantation of an AcrySof IOL through a corneal incision.

Purpose: Deep lamellar keratoplasty (DLKP) is an intricate procedure that preserves the host's endothelium, thus eliminating the possibility of endothelial graft rejection and potentially offering great benefits over penetrating keratoplasty. DLKP may be performed by a variety of techniques including viscodelamination, in which the stroma is separated from Descemet's membrane using viscoelastic.

Methods: Here we present an operative complication of this technique, which was not initially recognized, that caused significant morbidity to our patient and eventually led to the eye requiring a full thickness regraft.
