A bloat trocar (top), after sterilization, can be used to make a stab incision in the fornix. In the middle, a home made spear with a pointed V-shaped tip. At the bottom, a homemade stainless steel shaft with a sharp beveled cutting end [length 50 cm, diameter 2 cm]; made from the shaft of a defunct IV stand. The legs of a retired small animal examination table can also be used for this purpose.
