SECONDARY outcome

Timeframe: 6 months

Describes the scores on a scale and range from 0-3. Higher score represents more severe dry eye. Score 0 = no dry eye symptoms, score 1 = mild dry eye symptoms, score 2 = moderate dry eye symptoms, score 3 = severe dry eye symptoms.

SECONDARY outcome

Timeframe: 6 months

The cornea is divided into 5 zones, and the inferior zone 5 was assessed for staining pattern. Grade 0= no staining, grade 1= trace staining, grade 2= mild staining, grade 3= moderate staining, and grade 4= severe staining.

SECONDARY outcome

Timeframe: 6 months

The conjunctival staining is divided into 6 zones. Each zone received a score for staining with lissamine green. Grade 0= no staining, grade 1= trace staining, grade 2= mild staining, grade 3= moderate staining, grade 4= severe staining. Data from different zones was combined and the total value was averaged.
