Abstract: We prove that any compact topological orthomodular lattice $ L$ is zero dimensional. This leads one to show that $ L$ is profinite iff it is the product of finite orthomodular lattices with their discrete topologies. We construct a completion $ \overline L $ of a residually finite orthomodular lattice $ L$ having the property that every element of $ \overline L $ is the join of meets of elements of $ L$. Necessary and sufficient conditions for $ L$ that $ \overline L $ is the MacNeille completion are obtained.
