Abstract: A combination ophthalmic device includes various eye testing instruments in a single hand held device. The combination device is in the general configuration of a double ended occluder with an elongated central handle, but has different instruments at each end. One end has an occluder on one side thereof, with a fixation target instrument on the side opposite the occluder. The fixation target includes a plurality of characters each of a different size, and may be rotated to select an appropriate size target to test near visual acuity and other eye functions. The opposite end includes a Maddox rod instrument and a translucent red lens, each in its own circular enclosure. The red lens is used to test for diplopia (double vision), while the Maddox rod instrument is used to test for phoria, or correspondence between the two eyes. A plurality of pinholes is also provided to test visual acuity, with the pinholes being divided into two groups of different sized holes.
