Leopard Gecko Lost Toes?

How is your moist hide situated? Is it on the warm or cool side of your gecko's tank? It's best to have it either on the warm side if you don't mind spraying it frequently or in the middle of the tank if you want to spray it less frequently. On the warm side, the water evaporates more quickly, but there is a higher humidity factor as a result. In the middle, it will be suitably humid and evaporate a bit more slowly.

Lost toes generally have no effect on the geckos that owned them. I'm sure they're much happier with all their toes and there is always a risk of infection with injuries like these, however small they may be, so of course we'd like to avoid it happening.

These guys are notorious for getting 'toe caps' even when they have everything they need for shedding. I'm not sure what kind of soaks you're giving your gecko, but if you haven't already, try simulating a humidity chamber for him. Fill a tupperware or other sort of plastic tub up with warm (not hot) water and put the gecko in, then close the lid with small holes for air. Let your gecko stay in there for 10-15 minutes, then try Q-tipping the shed off his toes. The Q-tip should also be moistened with warm water for best results.

If this doesn't work, you may have to be a little rougher with the shed. If you can loosen it with the Q-tip, but not quite remove it, grab the loose flap of skin between two fingernails if possible, or tweezers if not, and gently pull. If it gives too much resistance, don't, as you might injure him. If you can gingerly work it off, great. I sometimes have to do this with my leo, as her toe caps can be quite stubborn at times.

Nothing too bad unless infections set in so keep an eye on him, seems to be a common occurrence with Leo's & many other gecko's beings they're toes are delicate, small & fragile... so always keep a shallow soaking bowl in his habitat - one he can soak in or drink from as he chooses & add wet paper towels or newspaper to his hide when he's shedding especially - not mosses or anything like that which can wrap around their toes causing this kind of loss as well !! Take Care

I am unsure to why Hikaru has been losing toes because it sounds like you have been doing everything right. If he is still climbing well now then it may not affect him at all and if it does it will probably only affect him in a few years when he will be less active and not as good at climbing if it does affect him at all. just keep doing what you are doing and good luck. Hope I helped.
