Purpose: To evaluate changes of ocular surface dynamics using Keratograph 5M for 3 months after vitreoretinal surgery. Methods: Eighty-three patients were divided into three groups: phacoemulsification group, vitrectomy group, and combined group. Keratograph 5M was performed for all patients at 1 week, 1 month, and 3 months after the surgery. Ocular surface dynamics parameters measured by Keratograph 5M, including noninvasive keratograph first tear film breakup time (NifBUT), noninvasive keratograph average tear film breakup time (NiaBUT), and tear meniscus height (TMH) were compared among the three groups over time. Results: The mean age of all patients (46 men and 37 women) was 62.2 ± 8.4 years. NifBUT and NiaBUT were significantly decreased at 1 week after surgery compared to those at baseline in all three groups (all p < 0.001). NifBUT and NiaBUT in the phacoemulsification group almost recovered to the preoperative level, while those in the vitrectomy group and the combined group were still significantly less than those at baseline. NifBUT and NiaBUT in the phacoemulsification group were significantly longer than those in the vitrectomy group and the combined group at 3 months. After 1 week, TMHs were significantly higher in the vitrectomy group (p = 0.001) and the combined group (p = 0.022) than in the phacoemulsification group, while TMHs were significantly less in the vitrectomy group (p = 0.010) and the combined group (p < 0.001) than in the phacoemulsification group at 3 months after surgery. Conclusions: These results suggest that vitreoretinal surgery could induce alteration of ocular surface dynamics for 3 months. The vitrectomy group and the combined group showed tear film instability compared to the cataract surgery alone group. Patients who underwent vitreoretinal surgery experienced more severe dry eye syndrome symptoms than those who underwent cataract surgery. Thus, managing dry eye syndrome after vitreoretinal surgery should be considered important for patients.
