Abstract Details



Purpose:

Cyanoacrylate glue is used to close small corneal perforations, typically under 2mm diameter. The application of cyanoacrylate corneal glue is a useful skill for all ophthalmologists to use in an acute setting. Acquiring practical familiarity with this technique is of benefit, and forms part of the ophthalmic curriculum in the UK as a practical skill residents have to acquire during training. We describe a cheap and simple model to facilitate practice of corneal glue application.

Setting:

Anterior Segment Service, Kings College Hospital, London , UK

Methods:

Materials required for corneal glue application include cyanoacrylate glue, ophthalmic surgical spears, sterile cotton buds, carbomer (2 mg/g), clear sterile drape. 4mm circular tissue punch and insulin syringes. The only additional equipment needed for this model are eggs, an instrument to punch small holes in the eggshell (eg 21G needle), and a 2ml syringe filled with normal saline. The punch is used to create a hole in the eggs. Saline can be injected into the egg to encourage simulation of a leaking wound. The materials listed above were used to close defects in the egg using a patch of corneal glue.

Results:

We demonstrate the practical aspects of using this model in the poster

Conclusions:

This technique provides a simple method to allow individuals to practice the skill of applying corneal glue. This technique is often performed in an acute setting, and increased familiarity with the technique will help increase confidence in individuals performing it for the first time.
