The Effect of Surface Anesthetics

  • Jörg Draeger


Surface anesthesia plays an increasingly important role in clinical ophthalmology. In the past it was mainly used for tonometry and the removal of corneal foreign bodies. Nowadays a number of diagnostic measures need surface anesthesia: the use of contact lenses for the examination of the fundus or the chamber angle would be impossible without the use of mild and quickly acting surface anesthetics. Electroretinography and echography also need a surface anesthesia of the cornea. The demand has increased for rapidly acting anesthetic agents which should be free of any side effects. This demand is mainly due to the increased need for glaucoma Screening with the applanation tonometer.
