Back rower Callam had a clear-out operation on his knee after returning from World Cup duty while Easson underwent surgery on his ankle and both operations went according to plan.
As a result, Robinson admits he was satisfied with the outcomes from both operations and is looking forward to welcoming the duo back into the first team fold in the future.
Robinson said: "We are looking forward to having them back 100% fit when they return. They are both valued players and we will do everything to aid their recoveries."
Callam revealed his operation was a precautionary measure designed to stem the threat of suffering a long-term knee problem.
Callam said: "I was experiencing pain in my knee every time I fell over and I was having it heavily strapped.
"In a game when your adrenaline is running it was fine, but before training it was causing me problems.
"According to the surgeon Gordon Mackay, I could have left it until the end of the season, but then there was the probability the hole could have got bigger and resulted in me being out for three to four months.
"So this way we sorted the problem out early enough. It was more of a tidy-up operation than anything else. I think the general timescale for something like this is three to four weeks.
"I spoke to the surgeon, Gordon and he said it went very well. It was the sort of operation that we weren't sure needed to be done or we could leave it. But he was very pleased that we did it."
The 24-year-old admits he is targeting a first team return because he is keen to get involved in match action again after the World Cup.
He added: "The World Cup was an enjoyable experience for me, but I was just desperate to get some game-time, so I'm really looking forward to getting back to playing with Edinburgh.
"The guys have played really well while the Scotland players were away, so there is lots of competition for places when we get back."
Meanwhile, Easson is expected to be a longer term casualty with his first team return planned for the New Year.
And the 23-year-old, who recently recovered from a broken leg, admits it has been a major disappointment, but one he is aiming to overcome.
Easson said: "My primary goal is to get fit. I've been told I will probably be out for about three months, so I'll target the New Year and try to play as many games as I can.
"Hopefully all the bad luck is out of the window now."
