Postoperative adhesions are a natural consequence of surgical tissue trauma and healing and may result in infertility, pain, and bowel obstruction. Adherence to microsurgical principles and minimally invasive surgery may help to decrease postoperative adhesions. Some surgical barriers have been demonstrated to be effective for reducing postoperative adhesions, but there is no substantial evidence that their use improves fertility, decreases pain, or reduces the incidence of postoperative bowel obstruction.

While the authors cannot establish causality between Demodex and chalazia, these findings suggest that D. folliculorum indirectly may be involved in the pathogenesis of chalazia via its effect on the anterior eyelid margin.
Objectives:
The prosthetic replacement of the ocular surface ecosystem (PROSE) device is used to treat difficult-to-manage ocular surface disease (OSD) and ectasia. Previous studies have demonstrated positive treatment outcomes. This study aims to document treatment failures to better tailor treatment and address limitations with its use.
Methods:
Retrospective chart review of consecutive PROSE fits performed at Northwell Health from 2012 to 2016. Reasons for patient discontinuation of treatment were documented, and potential risk factors for treatment failure were assessed.
Results:
The total number of eyes treated was 125. Fifty five eyes had ectasia, 67 had OSD, and 3 had both ectasia and OSD. A total of 8/125 (6.4%) of eyes failed treatment; 6/8 (75%) of failed treatments had worsening corneal edema, all of which had presumed risk factors for lower endothelial cell counts. Two eyes discontinued use secondary to intractable debris on the device, blurring vision. The most common diseases in patients failing therapy in descending order included: keratoconus and Fuch's dystrophy, ectasia after penetrating keratoplasty, and graft versus host disease. Those with presumed risks factors for lower endothelial cell counts (Fuch's dystrophy and patients with previous penetrating keratoplasty) were more likely to fail (22.2%) compared with those without a risk of a low endothelial cell count (1.6%).
Conclusion:
Although PROSE use has high success, corneal edema secondary to endothelial dysfunction is a potential limitation that may lead to treatment failure. Patients with lower endothelial cell counts after penetrating keratoplasty or with Fuch's dystrophy were more likely to fail treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
