Abstract
An apparatus for detecting ophthalmic disease such as a cataract in the lens of a patient's eye includes means for focussing a laser beam and slit light alternatively or simultaneously at a selected spot in the lens of the eye. The slit light is used in a monitoring or adjustment mode to illuminate the selected spot and its adjacent portion on which the laser beam is to be focussed for ophthalmic disease detection, thereby making easier the identification of spots to be measured in the lens of the eye.
