An ophthalmic tool includes an ophthalmic speculum for holding a patient's eye open and for guiding a lens probe of an eye imaging device to be directly contacted with a cornea of the patient's eye. The ophthalmic speculum includes two eyelid distensible frames, a mechanism to spread the eyelid distensible frames apart, and a probe guiding frame including a plurality of probe guiders spacedly extended from the eyelid distensible frames. Each probe guider has a peak upwardly extended above the eyelid distensible frame that serves as a guiding point and forms a probe guiding cavity within the guiding points of the probe guiders. The lens probe is guided to be disposed within the probe guiding cavity via the guiding points before and after the lens probe is aligned and contacted with the cornea of the patient's eye in a proper upright orientation.
