Effect of Artificial Tears on Ocular Biometry Parameters

Summary

Due to the instability of the tear film, the biometry often needs to be done multiple times in a clinical environment. The high variability of both short-term and long-term repeatability in keratometry of dry eyes is well-known. Consequently, enhancing the condition of the eye surface in individuals with dry eyes will result in improved precision when choosing the power of intraocular lenses (IOLs). This prospective and before-and-after self-control study will recruit 100 patients.
