JULY/AUGUST 2010 CATARACT & REFRACTIVE SURGERY TODAY EUROPE 15 H ydrophilic IOLs have many appealing characteristics, such as good optical clarity, good biocompatibility, a low incidence of dysphotopias, and good compressibility allowing implantation through small incisions. Many of these characteristics are due to the water content of hydrophilic lenses, which can vary from 18% to 30%. In cont...

An important technique used for the grading of voltage drop along high voltage ceramic insulators is to provide some surface conduction to bleed off accumulated surface charge. We have used metal ion implantation to modify the surface of high voltage ceramic vacuum insulators to provide a uniform surface resistivity of order 10 Ω/square. A vacuum arc ion source based implanter was used to impla...

Concentration profiles of nitrogen in vacuumannealed pand n-type single-crystal (1 0 0) InP implanted with 1]101630 keV 15N` ions cm~2 have been studied by Secondary Ion Mass Spectrometry (SIMS) and Nuclear Resonance Broadening (NRB) techniques. Damage induced by the nitrogen implantation was studied by Rutherford Backscattering Spectrometry (RBS) and channeling. Annealing the samples led to lo...
