A guide for use in medical procedures involving the eye comprises a shield for protecting portions of a patient's eye, as well as guide apertures through which an instrument, such as a needle can be inserted. The guide is positioned on the patient's eye, and a visible alignment member, such as a central opening will align the guide relative to the cornea, exposed through this opening. The guide apertures would thus be positioned so that penetration of the eye would occur at a site where no damage to the eye, and especially to the lens, could not occur. The guide apertures extend through cylindrical members that will position a syringe and insure proper entry of the needle into the patient's eye.
