Water-Free Cyclosporine: Four ESSENCE-2 Checks

Burning, scratchiness and blurred vision deserve an eye examination. Dry eye can involve too few tears, rapid evaporation or tears that do not work properly. An examination can assess tear production, evaporation and eyelids before treatment is chosen.¹

Check the population

ESSENCE-2 randomized 834 adults with moderate–severe dry eye to water-free cyclosporine 0.1% or its vehicle, twice daily for 29 days. Significant eyelid inflammation or meibomian-gland dysfunction was excluded. Novaliq sponsored and helped conduct, analyze and report it; two authors were employees.²

Separate the outcomes

The 0–15 corneal-staining score measures surface damage. Adjusted improvement was 4.0 versus 3.6 points (P = .03). But 0–100 dryness scores improved 12.2 versus 13.6 points: drug-minus-vehicle difference 1.4 (95% CI −1.8 to 4.6; P = .38). This did not demonstrate better dryness relief.²

Inspect the limits

804 contributed day-29 outcomes; missing or excessively late assessments were excluded. Secondary confirmation required both primary outcomes to succeed. Four weeks cannot establish lasting benefit or rank other cyclosporine formulations.²

Plan the review

The current US VEVYE 0.1% label covers dry-eye signs and symptoms. It lists instillation-site reactions and temporary reduction in visual acuity among common adverse reactions. The trial’s symptom result does not cancel that indication or establish that an existing prescription should be stopped.³

Keep the bottle tip away from eyes and other surfaces. Remove contact lenses before use and wait 15 minutes before reinserting them; separate other eye drops by at least 15 minutes. Ask the prescriber to review pregnancy or breastfeeding, because human pregnancy data are inadequate and milk data are unavailable.³

NEI describes artificial tears for mild dry eye and prescription medicines for more severe disease, alongside changes such as reducing smoke exposure and taking screen breaks. Ask what your examination showed, which symptom the prescription aims to improve and when to review its effect. Tell the clinician if symptoms interfere with daily activities.¹

“Give Each Concern Its Own Question” in My Body Changed. Now What? encourages a specific question and recording the outcome that matters. Bring both your symptom account and the examination findings to follow-up.¹
