What is a common outcome of punctual occlusion?

Punctal occlusion is a procedure typically performed to treat dry eye syndrome by blocking the tear ducts to preserve tears on the surface of the eye. By occluding the puncta, tears are retained in the eye longer, which directly contributes to alleviating the symptoms of dryness. Therefore, a common outcome of this treatment is the relief from dry eye symptoms, as it helps maintain a stable tear film over the ocular surface.

Increased tear production is not a direct result of punctal occlusion; while some patients may experience an improvement in tear stability, the procedure itself doesn't necessarily stimulate additional tear production. Decreased eye strain is more related to visual ergonomics and appropriate refractive correction rather than the effects of tear retention. Improved color vision is also unrelated to punctal occlusion; color vision primarily involves the function of cone cells in the retina and is not affected by tear film stability.
