You get optical isomerism when you have 3 bidentate ligands around one metal ion (octahedral shape). I have included a drawing of this. You also get optical isomers when one hexadentate ligand (usually EDTA4-) binds- the same idea but it is too difficult to draw. At A-level, you usually only come across optical isomerism in organic chemistry when there are 4 different groups are attached to a carbon. This is the only other time you come across it (i.e. a bidentate or hexadentate ligand in a complex ion)-it's tricky but just remember this one-off.
