Primary pterygium excision with conjunctival autograft can significantly improve dry eye symptoms and certain tear film characteristics, particularly by reducing Ocular Surface Disease Index (OSDI) scores and improving meibomian gland health, according to a study.
The prospective study included 33 eyes from 31 patients, with assessments conducted before surgery and at intervals up to 3 months postoperatively.
There was a significant reduction in dry eye symptoms, with a drop in the OSD score from 36.34 to 23.12. There were also notable improvements in meibomian gland dropout and a decrease in tear meniscus height postoperatively. However, other tear film parameters, such as noninvasive break-up time and lipid layer interferometry, showed less pronounced changes.
