Purpose. The continuous use of mask wear from pandemic induces instability in tear film due to the air blown up from the mask. The study’s objective was to assess the effect of type of mask wear and duration, including short-term wear of mask on TBUT. Design and methods. This was a cross-sectional, comparative study. A total of 90 (180 eyes) subjects (76 females) were involved in the study and were categorized into three groups, each comprising 30 subjects. Either the groups were given a surgical, cloth, or N95 masks to wear. Baseline TBUT was collected after 30 mins without mask wear; next TBUT was measured immediately after 1 min of mask wear and subsequently after every 30 mins for 3.5 hours among all the three groups. TBUT changes within the groups and between the groups were compared using Friedman ANOVA and the Kruskal Wallis test. Results. There was a significant decline in TBUT after 30 mins of mask wear only among surgical & cloth mask users and was stable in N95 wearers. There is no influence on TBUT for 1.5 hours among all the mask wearers. However, a subsequent continuous significant difference was evident from 2 hours among surgical and cloth mask users and at 3.5 hours within N95 users. N95 wearers have a higher TBUT, and surgical have the least TBUT. Conclusion. Surgical mask wears significantly influence tear film stability, followed by cloth mask wear because of air leak from nose wire. TBUT is minimally affected by N95 wear.

Injuries cause serious disturbance of the form and function of the organ of vision due to the damage and accompanying or remote complications and therefore have a high proportion to the structure of low vision, blindness and disability. One of the complications of penetrating wounds of the eye is iris cysts. Iris cyst can increase and cause pupillary block, secondary glaucoma, uveitis, corneal dystrophy, and therefore it requires surgical intervention. The goal of surgical treatment of an iris cyst is to ensure complete removal of the cyst. Objective: to estimate the clinical and functional results of treatment in a posttraumatic iris cyst, posterior subcapsular cataract and myopic astigmatism patient. Patient and methods. Patient B., 49 years old with posttraumatic retention iris cyst, posterior subcapsular cataract, compound myopic high astigmatism was examined. To determine the tactics of surgical treatment of the patient, a complex of General ophthalmology was performed (visometry, IOP measurement, autorefractometry, biomicroscopy, ophthalmoscopy), as well as special (B-scanning, optical coherence tomography of the retina) research methods. The follow-up period was 1 year. Results and discussion. To improve visual functions and prevent the development of secondary glaucoma, the patient was offered surgery — excision of the iris cyst and cataract phacoemulsification with toric intraocular lens. Simultaneous carrying out of two stages of the operation reduced the risks of postoperative complications and shorten the rehabilitation period. Conclusion. Positive optical and therapeutic effects were achieved as a result of the surgical treatment 44 years after an open eye injury: the eye is calm, the iris cyst is not detected, visual acuity has increased. The postoperative period showed the saving the stable and high visual and functional result with no recurrence of the iris cyst.
