Which adjunct therapy might be considered for dry eye beyond standard measures?

• A. Punctal plugs
• B. Laser therapy
• C. Cataract surgery
• D. Beta-blocker eye drops

Answer: (A)

When managing dry eye beyond basic measures, preserving the existing tears on the ocular surface is a key strategy. Punctal plugs achieve this by partially blocking the tear drainage openings (puncta), which slows tear outflow and increases tear film residence time. This helps the surface stay moistened longer and can relieve symptoms, serving as a convenient, reversible adjunct to artificial tears and lid hygiene. They can be temporary (dissolvable or removable) or more long-term, and are chosen based on symptom response and patient needs. Laser therapy can also occlude puncta, but it’s a more invasive option and is typically considered after simpler plug approaches or in cases where plugs aren’t effective. Cataract surgery doesn’t address tear dynamics and isn’t used for dry eye. Beta-blocker eye drops can worsen dry eye by reducing tear production, so they’re not used to treat it.
