Reviving the Legacy: Features of the TMH Device (Matsushita ed.) ‒ ver.1 / ver.2 Hook

Inspired by Dr. Tanitoʼs early work with the Sinskey hook, I independently designed a modified version of the TMH, known as the TMH Device (Matsushita ed.). The first-generation version, referred to as ver.1, incorporated elements of traditional external trabeculotomes while preserving the basic concept of the Sinskey hook. This design emphasized operability, safety, and tactile feedback during surgery. The newly developed ver.2 hook represents a refined version of the original TMH Device (Matsushita ed.), building upon the strengths of the ver.1 while significantly improving handling and insertion characteristics. The TMH Device (Matsushita ed.)̶from the original ver.1 to the evolved ver.2 version̶represents a thoughtful adaptation of foundational μLOT concepts, rooted in the pioneering work of Dr. Tanito. This device provides a reliable, domestically developed option for surgeons performing minimally invasive glaucoma surgery, contributing to both surgical precision and patient safe
