We investigated protein accumulation on disposable extended wear contact lenses. Fifteen volunteers were fit with one low water content, non-ionic lens (Bausch & Lomb's SeeQuence) randomly assigned to one eye and a high water content ionic lens (Vistakon's Acuvue) assigned to the fellow eye. During the first 7 weeks of extended wear the lenses were removed(More)
We investigated and compared the initial composition, morphology, and time course of deposits on individual soft contact lenses of different water contents and surface charges in order to evaluate the potential for antigenic reactions and to predict the optimal frequency of lens replacement. Newly manufactured lenses were worn for graduated periods of time(More)
— Northrop Grumman Aerospace Systems (NGAS) has been developing InP-based heterojunction bipolar transistor technology for next generation high performance aerospace, defense and commercial applications. We present highlights and status of our production and advanced InP HBT technologies including ultra-high speed 0.25 micron emitter InP HBT.
To evaluate the mechanical or biochemical insult to the cornea induced by overnight rigid gas permeable (RGP) or soft contact lens (SCL) wear, punctate, stipple staining and corneal blotting were evaluated by biomicroscopy in a group of 23 subjects who participated in a single overnight in-laboratory test session. The soft lens-wearing corneas typically(More)
—Static frequency dividers are widely used technology performance benchmark circuits. Using a 0.25 m 530 GHz /600 GHz+ max InP DHBT process, a static frequency divider circuit has been designed, fabricated, and measured to operate up to 200.6 GHz [1]. The divide-by-two core flip-flop dissipates 228 mW. Techniques used for the divider design optimization and(More)
The effects of time, eye patching, and lens flexibility on rigid lens adherence was evaluated in five overnight, in-laboratory test sessions. Patching was investigated with a group of 11 subjects in two overnight test sessions. Sleep time and lens flexibility were investigated in three separate overnight test sessions with two groups of subjects wearing two(More)
