A total of 50 eyes underwent repeated measurements to assess instrument stability, while 91 were divided into p-DE and control groups with mean tear break-up time (mBUT) &amp;lt;10\u202fs and mBUT \u226510\u202fs, respectively.

After using DQS, the tear meniscus height (TMH), the first breakup time and the mBUT all increased in the p-DE group (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05), yet they were still lower than those in the control group.

Combined correlation analysis and logistic regression analysis revealed that changes in steep keratometry and TMH after treatment with DQS eye drops were the main factors affecting IOL power change.
