This invention relates to potent potassium channel blocker compounds of Formula I or a formulation thereof for the treatment of glaucoma and other conditions which leads to elevated intraoccular pressure in the eye of a patient. The method may comprise generating a plurality of output signals from a single I component Gm stage and a single Q component Gm stage. An arm is attached to the shaft. The signal processing module converts the electrical signal into a digital signal. A horizontal line extending from the transfer cylinder defines an opening angle of less than 45\xb0 with the rollers of the dampening unit.
