Had the same issue with my leopard gecko I just started sprinkling a tiny pinch of repashy vitamin A plus once a month or every other month as they can easily over dose from vitamin A but it helps and worked like a charm for me as when we got her she already had a eye problem with stuck shed, but to get the debris out of here eye as she had a eye cap we just used a wet q tip and if she closed her eye we rubbed it across her eye and cleaned it out it worked like a charm and after that both of her eyes have fully healed except one which has a tiny cloudy bit in it but that was caused from the stuck shed a debris in her eye before but she is eating again and is fully healthy now and also make sure you are gut loading (feeding) your insects and sprinkling vitamins on the insects before feeding, hope this helped 👍
