Purpose:

To innovatively compare the tear film stability assessing noninvasively by Javal-Schiotz keratometer (Tear Deformation Time [TDT]) and invasively by slit lamp (Invasive Tear Break up Time [I-TBUT]).

Methods:

TDT and I-TBUT were assessed in only one eyes of one hundred healthy young participants aged from 18 to 25 years (Mean ± Standard Deviation = 20.49±1.80). Healthy ocular surface was considered as inclusive criteria. Nonparametric statistical analysis was performed to compare the TDT with I-TBUT and reveal correlation between them.

Results:

The TDT values (Mean: 22.84 ± 20.14 seconds) were significantly higher than the I-TBUT (Mean: 15.73 ± 8.89 seconds) data (P= 0.027). Neither TDT nor I-TBUT was affected by gender of the subjects. A significant direct correlation was detected between the TDT and I-TBUT data (Spearman’s ? = 0.458, P <0.0001). Neither I-TBUT nor TDT had significant relationship with age and sex factors.

Conclusion:

Our findings indicated that tear stability prolongation results obtained by TDT technique were significantly higher than the I-TBUT method outcomes. Noninvasive nature, easiness, basal tear film evaluation, availability, inexpensiveness, Fluorescein nonuse and accessibility in the clinic (no need for Para-clinical equipment) are benefits of the TDT technique.
