Does anyone know of a trick or technique for getting ointment into your horse's eye?. My Arab needs a little ointment for a slight corneal abrasion. But he just sqeezes that eye shut tight and I'm not sure I'm getting any medication into that eye at all. I've tried forcing the lids open, but I just can't seem to do it.
Any help would be appreciated.

It sure isn't easy.. Cheno has ERU and last summer he got a fungal infection which led to lots and lots of medicating.

All I can say is to try lots of different configurations with how you hold his head. I like to get right up against the head so if they swing it I go with rather than getting whacked, etc. I have used the head over my my shoulder, which works sometimes. Rest your arm and heel of your hand against him so you move with him, hold his head steady with the other hand, arm over his head. Big PITA isn't it? Having someone hold your horse and give him a tasty tidbit may help with keeping him occupied but it rarely worked for me.

Practice a bit without the medication first.

Just pull the lower lid down, sort of roll it with your thumb until the conjuntiva is exposed and you have a little pocket between the lid and the eyeball and squeeze a line into there. The blinking action will distribute it over the eye.
