An angle-based glaucoma surgery training program on human eyes

To improve surgical training for angle-based glaucoma, human corneoscleral rims can be used as a low-cost model and resource. To study the effects of a low-cost model for anterior chamber angle gonioscopy and microsurgery on human corneoscleral tissues in a wet laboratory to improve surgical skills of residents. Corneoscleral rims left after a keratoplasty procedure and/or pimples taken from deceased donors were included in this analysis. Inverted rims were once used as teaching aids for slit lamp biomicroscope courses on fundamental angle anatomy. To mimic indirect gonioscopy, direct gonioscopy, goniotomy, and other procedures involving the angle of the eye, an artificial cornea and anterior chamber were placed over the real cornea in the model. Quantitative assessment was reserved for direct gonioscopy and goniotomy activities (intended to mimic intraoperative gonioscopy and other angle-based procedures), while qualitative assessment was applied to the remaining exercises. A total of 65 locals participated in the simulation. A mean age of 26.69 ± 1.74 years was found. This included slit lamp examination of angle anatomy (n=55) and indirect gonioscopic examination of the cornea (n=55), all performed by ophthalmology residents. 10 glaucoma fellows used a simulated eye to perform direct gonioscopy and goniotomy. For the most part, fellows improved with practice, both in terms of ability (P
