should be first tapped. The eye then is soft, and the puncture of the 

 sclera is more difficult. The best method is, therefore, first to stick 

 the syringe needle through the sclera, and then to puncture the 

 anterior chamber, while an assistant holds the syringe. When pieces 

 of tissue are to be introduced into the vitreous, the anterior chamber 

 must always be punctured before opening the sclera, which latter must 

 be done with the greatest care. 



If it be especially desirable that the eye should be inoculated with- 

 out wounding any vascular tissue, this can always be done through 

 the centre of the cornea and lens (Komer). 



The lids should be stitched after every inoculation of the eye. It is 

 not necessary to stitch the whole thickness, but merely to bring a fold 

 of skin from above or below over the opposite lid.
