Especially when prolapsus iridis, or threaten ing prolapsus has existed, whereby the pupil has lost its central position, or where, with forward projection of the flap, the wound surfaces do not perfectly correspond, we seldom Obtain a completely normal arching of the cor nea. If the deviation is slight, the power Of vision may still be quite sufficient but on accurate investigation it now appears that the acuteness is defective, and the astigmatism is in this instance also partly capable of correction by giving an Oblique position to the convex glass, or by combination with a cylindrical one.
