This report describes a corneal tunnel incision that is self-sealing and does not leak when pressure is applied to the posterior lip of the wound. The success of the incision is in the construction of a single hinge. Results in patients who had the procedure are discussed.
In a series of 34 vitrectomies performed over more than three years, sodium hyaluronate was used in a new vitrectomy technique that facilitated the removal of vitreous. Sodium hyaluronate simplified the procedure, eliminated the use of any special surgical instrument, and prevented trauma to the vitreous cavity. No severe postoperative complications developed, and 65% of the patients attained a visual acuity of 20/20 to 20/30.
