B: baseline; 1: 1 month; 2: 2 months; TMH: tear meniscus height; TBUTF: tear film breakup time first; TBUTA: tear film breakup time average; CNFD: corneal nerve fiber density. Satisfaction: before: pretreatment satisfaction with ocular surface; after: posttreatment satisfaction with ocular surface; following advice: compliance with the doctor's advice; improvement: satisfaction with therapeutic effects. values of less than 0.05 were considered statistically significant and are expressed as 1 month versus baseline, #2 months versus baseline, and 2 months versus 1 month in the same group.
