Dear Editor, Intraocular lens (IOL) fracture is a relatively rare complication of cataract surgery during IOL implantation [1]. Foldable IOLs specifically are often fractured by either forceps or injector systems during IOL loading [2,3]. To improve the efficacy and safety of cataract surgery, many preloaded IOLs have been developed and are widely used. Here, we report the first optic fracture ...

The suspension of the crystalline lens in the eye was studied in 11 species of teleost (bony fish) from 10 families and 7 orders by light and electron microscopy. In all species there were 4-5 ligaments in about the equatorial plane of the eye, in which also the tendon of the retractor lentis muscle attaches to the lens. In two cichlid species two additional ligaments were found running from th...

The aim of the present study was to evaluate the difference in treatment plan quality, monitor units (MUs) per fraction and dosimetric parameters between IMRT (intensity-modulated radiotherapy) and RapidArc with single arc (RA1) and dual arc (RA2) for malignant glioma involving the parietal lobe. Treatment plans for IMRT and RA1 and RA2 were prepared for 10 patients with malignant gliomas invol...

Extremely simplified image projection technique based on optical fibers and a single Spatial Light Modulator is presented. Images are formed by addressing the modulator with especially iterated Fourier holograms, precisely aligned on the projection screen using phase factors of lenses and gratings. Focusing is done electronically with no moving parts. Color operation is done by spatial side-by-...

Proposed is a novel eye vision testing system based on micromachines that uses micro-optic, micromechanic, and microelectronic technologies. The micromachines include a programmable micro-optic lens and aperture control devices, pico-projectors, Radio Frequency (RF), optical wireless communication and control links, and energy harvesting and storage devices with remote wireless energy transfer ...

The purpose of this study was to investigate magnetic resonance imaging (MRI) of the normal feline eyeand optic nerves using T1-weighted and T2-weighted images. A total of 6 healthy female domestic short haircats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. Magnetic resonance imaging data werecollected using GEMSOW (Philips) at a magnetic field strength of 1.5 T. Dorsal, sagittal, a...

A new fundus camera can photograph a field extending anterior to the equator (148 degrees from the nodal point). The problems of reflection from the surfaces of the crystalline lens are minimized by fiber optic illumination from carefully chosen locations on the cornea. The camera may be used with monochromatic light of various wavelengths and is equipped with interference filters.

Purpose To compare the visual acuity outcome of the ClearKone SynergEyes™ hybrid contact lens and Boston XO rigid gas permeable (RGP) contact lens in patients with keratoconus. Methods Twenty-eight eyes with keratoconus participated in this study. The visual acuity was examined once with the RGP lens and once with the ClearKone SynergEyes™ hybrid contact lens. Results The mean corneal kerat...

Introduction: In this paper, by complete definition of human eye containing the various parts and their materials, the difference between this model and a homogeneous water phantom are compared for two ophthalmic plaques using 125I and 103Pd. Material and methods: The simulation of the two phantoms were performed in the MCNP-4C code and by using the geometry of a three-dimensional eye, differen...
