The other end of the suture, whichpasses through the tendon, is then laid over the former andtied, drawing the tendon and, with it, the conjunctiva for-ward as far as the fixation-suture. I have used this method of Princes almost exclusively for manyyears whenever I have had to do an advancement, and have always hadgood results with it. Occasionally I modify the ligation of the suturesby simply tying the two ends of the suture which passes through thetendon with the two ends of the fixation-suture, the operator and theassistant making uniform traction on the sutures. In this way thetendon is spread out a little more as it is drawn forward. 6. In VerhoeffS operation, which results in a verystrong attachment, a vertical incision is made in the con-junctiva at a distance of 3.5 mm. from the cornea; theconjunctiva is undermined as far as the cornea ; the tendonis sought for, divided from its lateral attachments with the

The needle is to be reintroducedat the point of exit and carried a short distance in a hori-zontal direction. The same thing is then repeated at thepoint of entrance with the second needle. The two needleshaving been passed through the tendon at some point be-hind the scleral side, the assistant grasps it with a clamp anddraws it forward as far as necessary to bring the desiredpart on the scleral suture, which is then tied (Fig. 98, e).The piece of tendon contained within the
