Summary
AIM: To observe ocular surface changes after phacovitrectomy in patients with mild to
moderate meibomian gland dysfunction (MGD)-type dry eye and track clinical treatment response
using a Keratograph 5M and a LipiView interferometer.
METHODS: Forty cases were randomized into control group A and treatment group B; the latter
received meibomian gland treatment 3 days before phacovitrectomy and sodium hyaluronate
before and after surgery. The average non-invasive tear film break-up time (NITBUTav), first
non-invasive tear film break-up time (NITBUTf), non-invasive measured tear meniscus height
(NTMH), meibomian gland loss (MGL), lipid layer thickness (LLT) and partial blink rate (PBR)
were measured preoperatively and 1 week, 1 month and 3 months postoperatively.
