The insertion of the chandelier light is easier using hands rather than with the trocar forceps. But the surgeon must exert a relatively strong pressure to insert the tip of the chandelier through the sclera. If this does not succeed, the surgeon can expand the sclerotomy with a 23G cannula. The insertion is now easier, but the chandelier sits a little loose in the sclerotomy.
Conjunctival chemosis or haemorrhage may make it difficult to identify the sclerotomy. In such cases use a pressure plate (DORC, no 2117), or open the conjunctiva focally with scissors and forceps in order to visualize the sclerotomy.
