The shaft has a drug delivery lumen 122, the drug delivery lumen 122 in fluid communication with a drug fluid side hole 128 in the shaft 120.

Abstract: Disclosed is a method of determining an appropriately shaped soft contact lens for a subject with an irregular cornea, the method comprising the steps of: inferring or deducing the profile of the cornea over at least a portion thereof: selecting a first choice fitting lens, the selection being based on the profile of the cornea obtained in the preceding step; assessing the fit of the contact lens to the cornea, by investigating each of the following parameters; (i) translational movement of the lens on eye; (ii) rotation of the lens on eye; (iii) centration of the lens on eye; (iv) the perceived comfort of the lens for the subject; (v) the visual acuity of the subject when wearing the lens; and adjusting the choice of fitting lens, if required, according to the assessment and reiterating until a desired fit of lens to the cornea has been obtained.

Abstract: A suction nozzle holster whose upper rim is provided with a notch into which a suction hose can be forced in order to constrict the hose and, hence, curtail the vacuum conditions in a suction nozzle.

Abstract: A suction nozzle holster device is provided with three possible operating positions through the use of a mounting channel component having a left, a center and a right key plate/key nub system that can each be respectively inserted into a cooperating keyway slot/nub receiver opening system mounted on a rear portion of a holster mounting component of the device. This arrangement gives the holster device three distinct operating positions.

Abstract: A holster apparatus for a medical suction tube is provided with a cooperating array of individual sterile sacs. Preferably, the cooperating array of individual sacs is a roll of such sacs having a line of perforation between each sac, or a nested array of such sterile sacs.
