PURPOSE It is aimed to evaluate the technical feasibility, safety, outcome, and incidence of complications after clear corneal phacoemulsification with foldable intraocular lens implantation (IOL) and triamcinolone assisted pars plana vitrectomy in patients with proliferative diabetic retinopathy. METHODS The results of combined phacoemulsification, in the capsular bag foldable intraocular le...

In this paper, a method is proposed for geometrically constructing thick panel structures that follow the kinetic behavior of rigid origami by using tapered or two-ply panels and hinges located at their edges. The proposed method can convert generalized pattern of rigid-foldable origami into thick panels structure with kinetic motion, which leads to novel designs of origami for various engineer...

Rigid origami is a class of origami whose entire surface remains rigid during folding except at crease lines. In this work, we explore the idea of determining distinct shapes that can be realized by a given crease pattern. Typically, crease pattern is designed with a single target shape in mind. However, as the advances in material science and robotics engineering enable the realization of self...

The protein universe corresponds to the set of all proteins found in all organisms. A way to explore it is by taking into account the domain content of the proteins. However, some part of sequences and many entire sequences remain un-annotated despite a converging number of domain families. The un-annotated part of the protein universe is referred to as the dark proteome and remains poorly char...

BACKGROUND The use of conventional foldable hydrophobic intraocular lenses (IOLs) in microincision cataract surgery (MICS) currently requires wound enlargement. We describe a combined surgical technique of MICS and trabeculectomy with insertion of a foldable IOL through the trabeculectomy fistula. METHODS After completion of MICS through two side port incisions, a 3.2 mm keratome is used to e...

Objective. To compare patient's satisfaction level in performing routine activities during daylight and night vision after implantation with rigid, foldable, or rollable posterior chamber intraocular lens implants in uneventful cataract surgery. Design. Retrospective, cross-sectional. Place and Duration of Study. PNS SHIFA Hospital, Karachi, from Nov. 2009 to Nov. 2010. Methodology. 91 cataract...

We assessed the outcomes of the use of anterior chamber foldable lens for unilateral aphakia correction at the University Teaching Hospital of Yaounde. In this retrospective, non-comparative, consecutive case series study, we reviewed the records of patients who underwent an operation for aphakia correction by the means of injection of an angular supported foldable lens between January 2009 and...
