Methods and Analysis: A descriptive study. The pig head dissection was performed at the abattoir for convenience. The orbital tissue thus obtained was used to set up the wetlab workstation. Results: A cost-effective, low technology, affordable set-up for ophthalmic surgical wetlab protocol was developed. High resolution photographs of the procedure were taken and were presented for ease of description. The dissection protocol was test-run at an ophthalmic surgical training workshop. Conclusions: The porcine orbit and the wetlab setup were available and affordable. The dissection in the abattoir is easy and reproducible. The orbit was used instead of the enucleated globe and this ensures stability throughout surgical practice sessions.展开更多
