<p>The invention relates to ophthalmology and, more particularly, to a corneal incision marker adapted for use in surgical treatment, notably that of myopia. An instrument of this invention comprises a case in the form of a bush accommodating a sight, and plates in planar arrangement at right angles to the plane of the sight. The plates are brought into contact with the cornea leaving indentations which serve as guidelines to perform incisions. According to the invention, each plate is mounted on a separate holder, the latter being attached movably radially with respect to the bush, the holders being rigidly secured in their entirety to said bush, and provision is made for a drive to effect smooth synchronized movement of the plate holders.</p> |
