61% of overall population with abnormal osmolarity
Of those that had abnormal osmolarity, 59% of the patients reported having at least three DED symptoms
Average osmolarity of patients with abnormal osmolarity (≥308 mOsm/L) or inter-eye difference (≥8 mOsm/L) = 318 mOsm/L
Average osmolarity of patients with normal osmolarity (≤308 mOsm/L) or inter-eye difference (≤8 mOsm/L) = 297 mOsm/L
Abnormal osmolarity can effect pre-surgical keratometry measurements
Patients with abnormal osmolarity were defined, within the protocol, as osmolarity ≥ 316 mOsm/L
17% of eyes with abnormal osmolarity had >1 D (diopter) of difference in keratometry cylinder values between two pre-surgical visits
10% of eyes with abnormal osmolarity had >0.5 D (diopter) of change in calculated IOL power
Abnormal osmolarity can play a role
A STUDY PRESENTED AT AAO†Found: |
All patients with contact lens discomfort and <8 hours of daily wear time had abnormal osmolarity.† These patients were put on a treatment to reduce osmolarity levels, resulting in an average increase of 4.6 hours in daily contact lens wear time.† |
Symptoms alone may not determine the cause of contact lens discomfort. Consider abnormal tear osmolarity as a potential reason.†
Use TearLab osmolarity data to inform your treatment plan based on disease severity and manage patient progress by evaluating therapeutic effectiveness.†
