“…The challenge in these procedures has been to stabilise the eye for the delicate procedures. Various devices have been developed to hold the enucleated eye in place for trainee surgery [28] [29] [30]. The need for these devices arose from the challenge of stability of the enucleated animal globe during wetlabs.…”

Objective: To describe the dissection protocol for the pig head to obtain the orbital tissue, as well as a simple setup for ophthalmic surgical wetlabs.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.

“…The use of vacuum for fixing eyeballs has efficiently solved this problem. The Otto15 and Mohammadi16 devices use automated vacuum machines for globe stabilisation and are inherently expensive and less portable, whereas the SAFE uses minimal elements with a simple spring-action syringe to generate the desired vacuum reproducibly, making it highly cost-effective and portable. A commercially available product, the Mandell device, uses a conventional syringe connected to a plastic tube attached to the globe holder 17.…”

Spring-action Apparatus for Fixation of Eyeball (SAFE): a novel, cost-effective yet simple device for ophthalmic wet-lab training

Achieving a formed and firm eyeball which is stably fixed in a holding device is a major challenge of surgical wet-lab training. Our innovation, the 'Spring-action Apparatus for Fixation of Eyeball (SAFE)' is a robust, simple and economical device to solve this problem. It consists of a hollow iron cylinder to which a spring-action syringe is attached. The spring-action syringe generates vacuum and enables reliable fixation of a human or animal cadaveric eye on the iron cylinder. The rise in intraocular pressure due to vacuum fixation can be varied as per need or nature of surgery being practised. A mask-fixed version of this device is also designed to train surgeons for appropriate hand positioning. An experienced surgeon performed various surgeries including manual small incision cataract surgery (MSICS), phacoemulsification, laser in situ keratomileusis (LASIK), femtosecond LASIK docking, Descemet's stripping endothelial keratoplasty, deep anterior lamellar keratoplasty, penetrating keratoplasty and trabeculectomy on this device, while a trainee surgeon practised MSICS and wound suturing. Skill-appropriate comfort level was much higher with SAFE than with conventional globe holders for both surgeons. Due to its stability, pressure adjustability, portability, cost-efficiency and simplicity, we recommend SAFE as the basic equipment for every wet lab.

“…The Mandell eye mount 22 is a user-friendly low-cost system with no hand-positioning skill training. Otto's device 17 offers better stability and intraocular pressure adjustability and also features hand-positioning skills training. The Porrello et al device 20 is complex and has multiple components: Plexiglass bulb holder, red reflector plate, and polyvinyl chloride base support.…”

“…A variety of platforms with different terminologies have been introduced to impart stability: globe fixation system, artificial eye/ocular socket, hollowed-out eye socket, artificial orbit, dummy orbit, eye-support device, and eye-model container. [17][18][19][20][21][22] Several features, namely, stability, maneuverability, and pressure adjustability, have been variably incorporated into these systems. A transilluminated artificial orbit has also been devised for vitreoretinal ophthalmic procedures.…”
