 upper and lower Kds, at the outer angle, the length

forceps, and make a small horizontal slit through the 

 hd, being careful not to w^ound the globe. Pass a small 

 grooved director through this opening, and with it gently 

 raise the lid from the eye. Pass in a pair of small sharp, 

 probe-pointed scissors to the heel, and, directed by 

 the probe, divide the lid with one cut, if possible, to 

 the inner canthus. Fine silk sutures should be used to 

 unite the conjunctiva to the skin, using care that the 

 knots remain externally.
