Which methods can clinicians use to assess dry eye signs before fitting soft lenses?

• A. Use patient questionnaires
• B. Use patient questionnaires, TBUT, ocular surface staining, Schirmer test, and evaluate tear film quality
• C. Intraocular pressure measurement
• D. Visual acuity assessment

Answer: (B)

Dry eye signs affect how comfortably and accurately soft lenses wear, so a thorough pre-fit assessment combines what the patient reports with objective checks of tear film and the ocular surface. Gathering symptoms through questionnaires helps identify how dry eye impacts daily life and lens comfort, revealing issues that patients might not voice spontaneously. Assessing tear film stability with a tear breakup time test shows how long the tear film remains intact between blinks, which is crucial because an unstable film can lead to fluctuating vision and lens intolerance. Looking for epithelial damage on the ocular surface with staining reveals areas where lenses might rub or accumulate debris, signaling potential wear problems. Measuring tear production with a Schirmer test helps detect aqueous-deficient dry eye, guiding material choices and wear schedules. Evaluating tear film quality, including the lipid layer and meibomian gland function, further informs how the tear film will behave under a lens and influences lens selection and care recommendations. Intraocular pressure measurement and visual acuity assessment don’t directly evaluate tear film adequacy or ocular surface health related to lens wear, so they aren’t as informative for pre-fitting dry eye assessment.
