Use of the phaco tip technique for lens cleavage and removal does not require manual hydrodissection using a syringe and cannula, or cortical removal using an irrigation/aspiration tip. The phaco tip is the only surgical instrument required for this technique. Its advantages include maintaining a stable intraocular pressure during cortical cleaving hydrodissection and lens removal, which includ...

MORE than two decades after the first efforts toward the application of spectral mixture analysis techniques to remotely sensed data [1], [2], effective spectral unmixing still remains an elusive exploitation goal. Regardless of the available spatial resolution, the spectral signals collected in natural environments are invariably a mixture of the signatures of the various materials found withi...

The procedures for purchasing surgical instruments and consumables are similar to those for purchasing equipment, which were addressed in our “Equipment for eye care” issue (number 73, September 2010). The major difference with consumables is that the number of items in stock (the ‘stock level’) must be monitored constantly. Consumables are generally fast moving and require frequent replacement...

This report describes the case of a 68-yr-old diabetic woman with severe deterioration of glycemic control caused by the use of a malfunctioning insulin pen device.

The Martian polar winter clouds were examined using both Mars Orbiter Laser Altimeter (MOLA) data and Thermal Emission Spectrometer (TES) data, with the hope that the chemical composition of the clouds could be determined. I begin by replicating some of the results of Ivanov and Muhleman (2001) by locating some south polar winter clouds of Mars. Locations, altitudes and brightness temperatures ...

statement of the problem the incidence of infectious diseases is considerably high among dentists and the team of dental care providers because of frequent exposure to blood and saliva. therefore, infection control regulations must be taken seriously in order to prevent cross-contamination purpose the aim of the present study was to investigate infection control measures in dental offices in ha...
