# Oral lactoferrin × gaps in direct evidence for chronic dry-eye treatment Verdict 2987 · Evidence Check Stored-material review date: Not recorded Original evidence cut-off: 2026-09-07 Review-criteria version: 1.0 Public page/material preparation date: 2026-10-16 Clinical papers were not read directly; existing review summaries were checked. No new clinical-literature search was performed. Unverified does not mean that research is absent or that there is no effect. ## Assessment scope - Population: The selected question concerns patients with general chronic dry eye. The preserved contextual trial enrolled small-incision cataract surgery patients without pre-existing dry eye, a different population; direct data by chronic-dry-eye diagnosis, duration, severity and subtype are unverified. - Ingredient, formulation and route: Formulation, actual exposure, adherence and direct effects of oral lactoferrin for the selected question are unverified. The preserved postoperative trial added oral lactoferrin 350 mg/day to routine care; this is not transferred to chronic-dry-eye exposure. - Dose: 350 mg/day for 60 days from the day after surgery identifies existing research exposure in a different population. No appropriate amount, duration or cumulative exposure for general chronic dry eye is set, and no dosing, product, postoperative-care or dry-eye treatment instructions are created. - Comparator: Direct comparisons of adding to or replacing standard care for general chronic dry eye are unverified. These are distinguished from the original postoperative comparison of routine care alone versus added lactoferrin, without placebo, with natural recovery and shared drops. - Measured outcome: Direct symptoms, tests, quality of life, function and patient-important outcomes in general chronic dry eye are unverified. Day-60 postoperative tBUT 13.9/7.86 seconds, Schirmer 30.9/15.86 mm and at least mild OSDI symptoms 26.6/42.8% in a different population are preserved separately as original context and are not transferred to chronic-dry-eye effects. - Duration: Direct duration, persistence after discontinuation, recurrence and long-term follow-up in the selected general chronic-dry-eye population are unverified. Original postoperative day 60, actual observation times, exposure and harm follow-up are distinguished. - Questions outside this scope: Transferring tBUT/Schirmer test differences to the same efficacy for OSDI, daily function, visual recovery or all eye health; Extending day-60 results in a selected population without pre-existing dry eye to all chronic dry eye, other surgery or long-term efficacy; Calculating new differences, effects, CIs, noncompletion rates or event counts from the original 64 randomized/58 completers, 32 per group/28 and 30 analyzed/6 noncompleters, test values or symptom percentages; Adding people, operated eyes, both eyes, tests, repeated measurements, times or two sheets as independent trials or participants; Using nonreporting of selected symptoms, no financial/competing interests reported, parent Good safety/I2 or historical verification to certify overall/long-term safety, independence or completed content review now; Filling absent subclaim score/status/axes from parent C54 or generating dosing, product, surgery, postoperative-care or dry-eye treatment instructions ## Checklist items ### N01 · How is the general chronic-dry-eye question distinguished from the postoperative question?
