Abstrakt: Background and Objective: Eye lesions during surgery are rare. Its common causes include direct trauma, chemical damage, and corneal exposure. Eye discomfort may present after surgery in the absence of structural damage. In our hospital, every patient under general anesthesia receives eye protection with eye occlusion associated in most cases with ophthalmic ointment application. We aim to analyze the incidence of eye discomfort with 0.2% carbomer application.
Methods: A cohort study was conducted. Patients who underwent surgery under general anesthesia lasting less than 4h between February and November 2017 were enrolled. We excluded patients with previous ophthalmologic pathology, those undergoing eye, otolaryngology, face or head surgery, and patients in which eye occlusion was not possible. For analysis, patients were divided into two groups: simple eyelid occlusion (Group 1) and eyelid occlusion plus ophthalmic ointment (Group 2). Primary outcome was the incidence of eye discomfort and secondary outcomes were to stablish associated risk factors.
Results: 400 patients were analyzed, 50% were exposed to 0.2% carbomer. There was no difference in patients' demographics. During the first 24h post-surgery 7.25% of patients showed visual symptoms, and at one-week postoperative no patient referred symptoms. Most frequent symptoms were blurry vision, pruritus, epiphora and red-eye. On multivariate analysis, the main risk factor associated with eye discomfort was 0.2% carbomer application (RR 13.5 CI 3.27-56.2). Emergent surgery and age were also found to be risk factors.
Conclusion: 0.2% carbomer does not prevent ophthalmologic symptoms after surgery and it may even increase them in short procedures.
