Dry Eye & Thermal 1-Touch in Santa Cruz

Dryness has more than one cause

Burning, grittiness, fluctuating blur, and even watery eyes can occur when the tear film is unstable. Some people do not produce enough watery tears; others lose tears too quickly because the oil glands in the eyelids are not working well. Inflammation, medications, contact lenses, and the environment can also contribute. Symptoms alone cannot identify the cause.

We examine the lids, tear film, cornea, and gland secretions, and review your symptoms and daily routine. Sudden pain, significant redness, light sensitivity, or a change in vision needs an urgent eye assessment.

Thermal 1-Touch: our preferred procedure for suitable gland dysfunction

Thermal 1-Touch applies controlled warmth to the eyelids. Warming can soften thickened oil in the meibomian glands; your doctor then uses gentle, directed expression to help release blocked secretions. The goal is to improve the oil layer that helps slow tear evaporation.

What happens during the visit?

1. Assessment and preparation. We confirm that heat and expression are appropriate, remove contact lenses, and prepare the lids. Your clinician explains whether anesthetic drops are needed.
2. Controlled warming. The device is adjusted to your lids and used under supervision. Treatment time is tailored to your condition; the manufacturer describes a 10–30 minute warming phase.
3. Gland expression. After warming, your doctor expresses the glands and cleans the lids.
4. Follow-up. We assess comfort and gland function and discuss any home care or additional treatment.

We review your health history and the device’s precautions before treatment. The manufacturer lists contraindications including diabetes and poor circulation. Heat can cause burns, so correct fitting and supervised monitoring matter. Read the manufacturer’s procedure and safety instructions.

Warmth and expression are supported as treatment approaches in dry-eye guidance. Results from a heating-device study apply to that device and the studied protocol. Large randomized trial evidence specific to Thermal 1-Touch remains limited, so expectations for the degree and duration of relief are individualized. Results and retreatment needs vary.

Punctal plugs: keeping tears on the eye longer

Tears normally drain through small openings called puncta near the inner eyelid corners. A punctal plug partially or fully blocks a drainage opening to conserve tears. We may use plugs alongside gland treatment when a patient has both tear deficiency and oil-gland dysfunction. Gland treatment addresses blocked oil glands; plugs conserve tears by reducing drainage.

We consider the type of dry eye and whether inflammation needs treatment first. Plugs may cause watering, irritation, loss of the plug, or, less commonly, infection. A Cochrane review found the trials too inconsistent and uncertain to establish a clear overall improvement in symptoms; individual patients may still benefit. Read the systematic review of punctal occlusion.

Omega-3 supplements: our recommendation in context

We may recommend omega-3 supplements for selected patients after discussing diet, medications, health history, and preferences. The evidence for symptom improvement is mixed, so recommendations are individualized.

The large DREAM randomized trial enrolled 535 people with moderate-to-severe dry eye. Over 12 months, 3 grams per day of fish-derived EPA/DHA did not improve symptoms or signs significantly more than an olive-oil placebo. The dose describes the study protocol; your clinician can advise on supplementation for your health history. Other studies and formulations have produced differing results.

Tell us about allergies, supplements, and medicines, especially blood-thinning medication, before starting a supplement. We discuss whether the potential benefit makes sense for you and review whether it is helping.

A plan for more comfortable eyes

Depending on your findings, care may also include artificial tears, lid hygiene, blink and screen-break habits, changes to contact-lens wear, or prescription treatment for inflammation. Comfortable home warming, if recommended, is different from a supervised Thermal 1-Touch procedure. Avoid excessive heat and follow your clinician’s instructions.

Science behind the options

• Olson, Korb & Greiner, 2003 — a small randomized paired-eye warm-compress study measured short-term tear-film lipid changes. Its findings concern short-term lipid changes with warm compresses; Thermal 1-Touch and lasting symptom relief require separate evidence.
• Brissette et al., 2015 — a randomized trial comparing two punctal-plug types, with retention as its main outcome. It compared plug types, with retention as its main outcome. Overall symptom benefit remains uncertain.
