Which surgeon is noted for using overlay sutures in corneal transplantation?

Overlay sutures secure a corneal graft by drawing and holding the donor edge to the recipient bed with the suture running over the surface of the cornea. This technique helps align the graft precisely and keeps the wound closed and stable as healing begins, which was crucial in the early days of corneal transplantation when ensuring graft survival was more challenging. Eduard Zirm is the surgeon most closely associated with this approach, because his pioneering 1905 transplant demonstrated that a full-thickness corneal graft could survive in a human eye, and overlay suturing was part of the methods used to achieve reliable graft apposition. His work established the practical viability of corneal transplantation and set standards that influenced later techniques. The other names are known for various contributions to ophthalmic surgery, but they are not the figures chiefly linked with the overlay suturing method in corneal grafts.
