We evaluate the spin-dependent beam shifts near the singularity for three typical optical interfaces, comparing our results with existing ones. Existing theories neglect the contribution of the wave vector component\n                    <jats:italic>k<\/jats:italic>\n                    <jats:sub>\n                      <jats:italic>y<\/jats:italic>\n                    <\/jats:sub>\n                    <jats:sup>\n                      <jats:italic>i<\/jats:italic>\n                    <\/jats:sup>\n                    near the FC singularities, potentially leading to erroneous results.
