Ocular surface changes following vitreoretinal procedures

Dry eye disease (DED) can lead to ocular discomfort as well as visual disturbances. Older adults are more likely to develop DED. They are also more likely to develop retinal diseases such as diabetic retinopathy and age-related macular degeneration, which may require vitreoretinal surgeries, lasers, and intravitreal injections. Posterior segment surgery may cause or worsen existing dry eye symptoms, albeit temporarily. Despite good anatomic and functional outcomes, ocular surface dysfunction can have a significant impact on the quality of life, lowering a patient's satisfaction with the retinal treatment. Preexisting DED, intraoperative tissue handling, and postoperative treatment may all contribute to the severity of ocular surface dysfunction. In this article, we have reviewed all relevant studies on the development of ocular surface changes and DED, as well as the impact of vitreoretinal surgeries and procedures on the ocular surface.
