Background: Different surgical treatment options are used to treat cataracts, such as Manual Small Incision Cataract surgery (MSICS) and Phacoemulsification. The present study compares the visual outcomes of phacoemulsification MSICS in senile cataract patients. Methodology: A quasi-experimental was conducted with 270 patients aged between 50 70. Patients diagnosed were included divided equally...

This Keynote Paper is concerned with the fundamental mechanics of granular materials with a particular reference to non-coaxial behaviour. The non-coaxial behaviour refers to the non-coincidence of principal stress directions and corresponding principal plastic strain rate directions during plastic deformation. At present, the majority of soil models used in geotechnical practice are those of a...

PURPOSE To determine the effect of phacoemulsification on macular volume and thickness using spectral domain optical coherence tomography examinations. METHODS Twenty-seven eyes of 27 subjects who underwent phacoemulsification were studied. All nine areas of the macula were examined by spectral domain optical coherence tomography preoperatively and 2 months postoperatively. Effective phacoemu...

PURPOSE To evaluate the governmental costs of patients undergoing phacoemulsification and extracapsular cataract extraction at a public hospital in a developing country. METHODS A prospective study was conduced with 205 patients. The subjects were randomized for cataract surgery using either phacoemulsification or extracapsular cataract extraction techniques. RESULTS Of the 205 patients, 10...

Coaxial couplers with high input RF power, usually operated at 500 MHz, are one of the critical components used in accelerators. To withstand high RF power, the couplers should be tested first, under identical conditions in a test stand. A waveguide coupled to a coaxial cable is used for this purpose. The parameter that indicates the amount of returned power loss is S11. By optimizing the dimen...

BACKGROUND We describe a case of intraoperative fracture of phacoemulsification sleeve during phacoemulsification surgery. CASE PRESENTATION Phacoemulsification surgery was performed in the left eye of a 58-year-old lady with grade II nuclear sclerosis & grade I cortical cataract. Towards the end of quadrant removal, there was anterior chamber instability with impaired followability of nuclea...
