Modified Safety-Razor Blade Holder for Temperature Control

Razor blade section in cataract surgery.

There are many techniques of cataract extraction and many types of cataract knives have been devised to facilitate an ideal section. Ultrasharp diamond knives were introduced by Durham and Luntz (I968). Sharpness is essential whether the von Graefe knife, the keratome, or corneal scissors are used, and for this reason disposable cataract knives, keratomes, and Bard Parker blades are widely used...

After induction of local anaesthesia, normal saline is injected to make the lesion bulge. A peripheral portion of the lesion is curetted for assess...

Individual blade pitch for yaw control

Individual pitch control (IPC) for reducing blade loads has been investigated and proven successful in recent literature. For IPC, the multi-blade co-ordinate (MBC) transformation is used to process the blade load signals from the rotating to a stationary frame of reference. In the stationary frame of reference, the yaw error of a turbine can be appended to generate IPC actions that are able to...
