Importance of Diagnosis

In a prevalence study conducted with over 9000 patients:

61% of overall population with abnormal osmolarity

Of those that had abnormal osmolarity, 59% of the patients reported having at least three DED symptoms

sss

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

Can abnormal osmolarity impact surgical outcomes?

17%

17% of eyes with abnormal osmolarity had >1 D (diopter) of difference in keratometry cylinder values between two pre-surgical visits

10%

10% of eyes with abnormal osmolarity had >0.5 D (diopter) of change in calculated IOL power

Contact Lens Dropout

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.^†

of symptomatic patients had abnormal tear osmolarity.

MANAGE

Use TearLab osmolarity data to inform your treatment plan based on disease severity and manage patient progress by evaluating therapeutic effectiveness.^†

Response to Therapy: Abnormal osmolarity decreases with effective treatment
