The full name "slit lamp microscope" is one of the most frequently used optical devices in ophthalmology. The position, nature, size and depth of the lesion can be determined by slit lamp microscope to clearly observe the orbit, conjunctiva, sclera, cornea, anterior chamber, iris, pupil, lens and 1/3 of the vitreous. If it is equipped with an accessory, the scope of inspection will be more extensive.
