Best Dry Eye treatment in World

The Schirmer test gives a good clinical measure of tear flow but is fraught with many errors, including the quality of the paper used and the techniques employed, and is therefore still a gross test of an unphysiological variety.

The various dye dilution tests are subjective and involve sampling errors.
The fluorometric technique of Maurice and Wright is also not suitable for clinical use.
Tear film break-up time (TBUT) may vary in the same patient and is unreliable
Symptomatology /Questionaire of dry eye :- 1) individual symptom score did not have a specificity and sensitivity to diagnose dry eye disease; 2) the individual symptomatology did not match the severity of dry eye disease; 3) the severity score by itself did not prove useful for diagnosis of dry eye.

DR. HANSPAL BHINDER THERMOMETRY AND HUMIDITY DRY EYE CLASSIFICATION

Grade1 (MILD): Thermometry difference between closed and open eye was 0.0±0.0 ºC.

Humidity difference from closed to open eye position was 0.99±0.03 RH% (0.9-1.0RH%).

Grade 2 (MODERATE): Thermometry difference between closed and open eyes was 0.0±0.0 ºC. Humidity difference was ?1.0 RH%-1.5 RH% (1.21±0.14 RH%).

Grade 3 (SEVERE): Thermometry difference between closed and open eyes was 0.0±0.0 ºC. Humidity difference was ?1.5-2.0 RH% (1.82±0.14 RH%).

Grade4 (VERY SEVERE): Thermometry difference between closed and open eyes was 0.0±0.0 ºC. Humidity difference was > 2.0 RH% (2.44±0.41 RH%).

Advantage of Closed Chamber Thermometry & Humidity in Dry Eyes

Very Early detection of the dry eye only with this test.
The only test to detect dry eye in reflex epiphora
Proper monitoring of the dry eye patient
Detection of the degree of potency of wetting agent
When to stop medication
Non-invasive, Quick
Quantification of values
Not affected by environmental factors
