ABSTRACT:
Apparatus and method for use in ocular surgery to enable the surgeon to determine the degree of self correcting astigmatism to apply to the eye during the suturing procedure. The apparatus comprises an ocular microscope provided with a device for directing a ring of light onto the anterior surface of the cornea of the eye such that the cornea will reflect the ring for viewing in the eyepiece of the microscope. The eyepiece is provided with means for determining the shape of the reflected ring and hence the degree of astigmatism applied to the cornea by the surgeon. In particular this means may be in form of a comparison ring which may be viewed in the same field of view as the reflected ring and being adjustable by the surgeon to provide a series of comparison rings for comparison with the reflected ring and corresponding to successive degrees of corneal astigmatism.
