Purpose: To develop a simple suture lysis technique for post-trabeculectomy examinations under anesthesia since slit lamp laser suture lysis in the clinic cannot be performed on infants and young children. Methods: An argon endolaser probe lysed 10-0 nylon suture through conjunctiva harvested from human cadaver eyes. Since suture lysis failed with the thick Hoskins lens, clear plastic from the suture package compressed the conjunctiva. The conjunctiva was examined histologically. Results: Argon laser suture lysis (250 mW, 0.1 sec, 488 - 514 nm) was achieved without conjunctival damage. Conclusion: The argon endolaser probe is effective for suture lysis when the slit lamp cannot be used.
