Purpose: To report a series of cases of Acanthamoeba keratitis (AK) in scleral lens wearers with keratoconus to determine whether this type of contact lens presents a greater risk for development of infection. Methods: ...

We present a new description of the spectrum of the (spin-) Dirac operator D on lens spaces. Viewing a spin lens space L as a locally symmetric space Gammaackslash operatorname{Spin}(2m)/operatorname{Spin}(2m-1) and ...

The aim of this study was to evaluate the effect of surface treatment of acrylic intraocular lens using Fluorine plasma or polyethylene glycol in the prevention of posterior capsule opacification. Forty rabbit eyes that ...

Kerr lens mode locked Ti:Sapphire lasers can operate in at least two pulsed modes. Several models were developed with the aim to describe the characteristics of these modes. Those based on iterative maps, can reproduce the ...

Tuberculosis (TB) control efforts are hampered by a mismatch in diagnostic technology. Lack of adequate early diagnostics and Multi-drug resistant (MDR) detection is a critical problem in control efforts. Alternate and ...

The lens is a transparent tissue in the anterior of the eye and its main role is to refract light on the retina. The lens consists of two types of cells: epithelial cells and fibers. Epithelial cells surround the anterior ...
