The fully automated trephine full-thickness glaucoma surgery in cadaveric pig’s eyes and live rabbit’s eyes

Abstract

Pilot study with fully automated trephine full-thickness glaucoma surgery in 10 cadaveric pig’s eye and 1 live rabbit’s eye; in 8 external approach (ab externo) and 2 internal approach (ab interno) in pig’s eyes ; 1 rabbit’s eye external approach (ab externo). The machine can cut cornea well 0.8 millimeter diameter and have good block clean cut ; in pig’s eyes and rabbit’s eye can create good form conjunctival bleb and in internal approach it can form non-traumatic conjunctival bleb more posteriorly. live rabbit’s eye after follow up for 6 months it can reduce intra ocular pressure (IOP) about 40% from 16 to 9.6±0.4 millimeter mercury which is the excellent result to control glaucoma (IOP below 12 around 10 millimeter mercury) and there are no complications such as endophthalmitis, cataract, uveitis, hypotony, and corneal decompensate.
