We do not have a good explanation for that, but it is probably due to a central nervous system mechanism, he said. One patient had conjunctival suture dehiscence that required a conjunctive graft. Three patients had segment rotation, which surgeons attempted to correct by making a locking loop for the implant on each end. Two patients did not experience refractive interference from the rotated implants, but surgeons restored them, fearing erosion of the conjunctiva at the abrupt edges. The technique is still in evolution.
Predictability needs more improvement, but the door is open for the reversal of presbyopia.
