Prevention of corneal complications for intensive care unit patients is effective way to avoid corneal damage. Polyethylene covering is transparent dressing creates moist chamber providing a barrier against tear-film evaporation and providing physical barrier to organisms Aim: this study was carried out to investigate the impact of polyethylene eye covers dressingon preventing corneal complications. Design: A quasi-experimental design. Setting: Trauma Intensive Care Unit at Assiut University Hospital. Subjects: A convenience sample of 120 eyes of 60 adults patients divided into study and control groups (30 patient for each). Tools: tool I Patient assessment sheet. Tool II: Richmond Agitation Sedation Scale. Tool III: Eye assessment tool. Tool IV:Eye care technique, eye lid closure and eye cover by using polyethylene eye cover. Methods: Researcher assessed each patient's eye and ability to maintain eyelid closure. Then, eye care technique was applied, eye lid closure and eye cover by using polyethylene cover to each patient’s eye for preventing corneal complications. Results: Finding of present study revealed that there was significant statistical difference between both study and control groups in 7th day in relation to corneal ulcer in right eye and left eye ( P = 0.001& 0.000) respectively .Conclusion: eye lid closure and eye cover by using polyethylene eye cover could be significantly effective in preventing corneal complications.
