This prospective interventional randomized study included healthy individuals without a history of dry eye disease. EvoTears are a water-free, preservative-free eye drops which act to stabilise the tear film lipid layer, relieving symptoms associated with evaporative dry eye and meibomian gland dysfunction (MGD). This prospective clinical study included 104 eyes treated with F6H8 four times daily for four weeks (group A) and 101 eyes that served as controls (group B).

showed a beneficial effect of F6H8 by immediately fusing with the precorneal tear film and compensating for surface irregularities. Additionally, the reliability of measurement of HOA and refractive data is more accurate when lipid-based tear supplements are used.Patients' and physicians' assessment indicated good efficacy and high tolerability of EvoTears, suggesting its suitability in postoperative management of the ocular surface in patients with dry eye disease. In addition, different devices for measuring HOA can only be compared with each other to a limited extent. Regular administration of lubricating eye drops is generally recommended prior to refractive surgery, especially if dry eye is suspected [ 4].

Three consecutive scans were acquired under mesopic lighting conditions for the right and then the left eye, by a single optometrist according to a standardized operating procedure, including standardized oral instructions for each patient. Changes of corneal wavefront aberrations in dry eye patients after treatment with artificial lubricant drops.Social media and advertising cookies of third parties are used to offer you social media functionalities and personalized ads. These glands produce the lipid phase of the tear film by secreting an oily substance directly onto the eyelid margins. EvoTears ® eye drops are characterized by a high yield - up to 280 drops per 3 ml content - and a low application frequency. Many products are tested and seldom achieve the desired result or relieve painful symptoms that affect the patient’s quality of life.

With many treatment options available today, a differential evaluation of specific AT supplements on the precorneal tear film would provide more evidence for ophthalmologists. We believe that these results are important for refractive surgeons and that future studies with larger cohorts and more assessment factors would be a valuable addition to this work. Nevertheless, it is difficult to compare studies in this context, as the type of eye drops used, the time between the last application, the number of applications and the measuring devices are inconsistent.Semifluorinated alkane eye drops for treatment of dry eye disease–a prospective, multicenter noninterventional study.
