Abstract: A neonatal incubator system includes an enclosure having a series of side panels that create a chamber that receives an infant. At least one of the side panels includes a porthole having a porthole door that is movable between open and closed positions. A rotary latch is positioned to engage the porthole door to retain the porthole door in the closed position when the latch is in a latched position. The rotary latch is designed such movement of the rotary latch to an unlatched position creates physical separation between the porthole door and a sealing gasket or bumpers located between the porthole door and the side panel. The rotary latch is designed such that a control knob can be moved to a cleaning position in which the control knob is spaced from the side panel to expose a liquid gutter that is formed as part of a stationary base.

Abstract: A progressive addition lens design device for designing progressive addition lenses to permit a patient to experience a variety of distance vision fields and reading vision fields. The device includes a frame adapted to hold in place in front of each of a patient's eyes three lens mounts, each lens mounts being adapted for adjustment in rotation and side-to-side translation. A third lens displaying the patient's base prescription mounted in one of the lens. A first and second lens is mounted in the other two lens mounts. The first and second lenses, each have a transition zone and a power ramp zone and they have complementary surfaces so that when stacked together they create a standard progressive addition lens with a distance vision field, a reading vision field and transition region.

Abstract: A low inventory method of making eyeglasses. Two lens elements having special complementary surfaces are provided. These lens elements can be positioned relative to each other to provide wide ranges of focus correction and astigmatism correction. Various preferred embodiments of the invention are described. In one embodiment the required inventory is only identical sets of two complementary lenses for providing correction for almost all needed eye correction for a typical population. In this embodiment, the lens units are first adjusted relative to each other to provide a desired focusing power. Astigmatism may be corrected by a small adjustment in a second direction perpendicular to the first direction followed by a rotation of the two lenses about the axis of the two lenses. When the adjustments have been made the two lenses are fixed with respect to each other and installed in eyeglass frames. Cutting to the shape of the eyeglass frames can occur either before or after the fixing.

Abstract: An eyeglass lens and manufacturing method using epoxy aberrator includes two lenses with a variable index material, such as epoxy, sandwiched in between. The epoxy is then cured to different indexes of refraction that provide precise corrections for the patient's wavefront aberrations. The present invention further provides a method to produce an eyeglass that corrects higher order aberrations, such as those that occur when retinal tissue is damaged due to glaucoma or macular degeneration. The manufacturing method allows for many different applications including, but not limited to, supervision and transition lenses.

Abstract: An apparatus for determining the objective refraction of a patient's eye includes a transparent window and a wavefront measurement device that determines aberrations in a return beam from the patient's eye after the beam passes through a corrective test lens in the apparatus. The wavefront measurement device outputs an instant display representative of the quality of vision afforded the patient through the test lens. The display can be a representation of a Snellen chart, convoluted with the optical characteristics of the patient's vision, an overall quality of vision scale or the optical contrast function, all based on the wavefront measurements of the patient's eye. The examiner may use the display information to conduct a refraction examination and other vision tests without the subjective response from the patient.
