I would remove the old leaves at their base - they always look a bit battered by the end of the winter and detract from the flowers. I remove them just as the new flower buds are showing in the late winter early spring.
The Ajuga and Lysimachia nummularia 'Aurea' that is growing around the hellebore is providing the perfect hiding place for slugs and snails. I would clear an area around the base of the hellebore, give it a feed with some Fish Blood and Bone according to the instructions on the pack, and then mulch with some organic material - garden compost or leaf mould would be best.
Keep the base of the plant clear of other plants and my bet is that the snail damage will reduce.
Hope that helps.
