Tissues, including muscle (whose inser- tion is first divided), are dissected up from the sclerotic as far back as equator of eye- ball. Flap thus formed is pulled forward and united by sutures to flap left standing at cor- neal margin, so as to cause the tendon to unite itself with the sclerotic at a point farther forward. Sometimes apiece of the muscle is excised so as to shorten it. If some conjunc- tiva is excised before bringing flaps together, effect is increased. Tendon of opposite mus- cle usually divided also, to increase effect. The operation is modified in several ways by different surgeons.

Or a narrow, probe-pointed knife is passed into punctum and along canaliculus, which is divided by raising knife from heel to point, no director
