Transconjunctival observation and suturing technique for invisible and insufficiently closed sclerotomy wounds using an inverted surgical contact lens in transconjunctival microincision vitrectomy surgery

摘要

Transconjunctival sutureless microincision vitrec-tomy surgery (MIVS) has become one of the standard surgical procedures in recent years. However, many studies have reported postoperative hypotony because of leakage from the sclerotomy wound after the transconjunctival sutureless MIVS1 was performed. The possibility of choroidal detachment causing postoperative hypotony and also an increase in the risk of endoph-thalmitis2 occurs with transconjunctival MIVS. To reduce leakage, techniques for a self-sealing sclerotomy3 and devices such as a trocar blade4 have been created. However, in practice, leakage from the wound has been confirmed to occur at the end of an operation. Chemosis, subconjunctival bleeding, and emphysema are experienced in many cases.
