Incidence of early complications requiring treatment plan changes after vitreoretinal surgery: a single-center study in South Korea

BACKGROUND: Information regarding incidence of treatment plan changes may be useful when discussing postoperative treatment plans for patients. Moreover, it may help establish a standardized postoperative treatment plan. This study aimed to evaluate the incidence of early complications requiring treatment plan changes in patients following vitreoretinal surgery and investigate its risk factors. METHODS: This single-center retrospective study included 465 patients who had undergone vitreoretinal surgery. The reasons, incidence, and timing of treatment plan changes within 14 days of surgery were identified. Potential factors associated with the changes, such as patient demographics, surgeon’s experience, diagnoses, and type of surgery were also analyzed. RESULTS: The treatment plan was changed in 76 patients (16.3%) at a mean of 4.0 ± 3.2 days after vitreoretinal surgery. The reasons for the plan changes were increased intraocular pressure (IIOP) in 66(86.8%), intraocular inflammation in 2(2.6%), corneal edema in 3(3.9%), leakage from the sclerotomy wound in 3(3.9%) patients, and combined IIOP and intraocular inflammation in 2(2.6%). The date of discharge was postponed because of treatment plan changes in 17 patients (22.4%). The incidence of plan changes was higher in patients who underwent gas or oil tamponade (P < 0.001) and those who underwent surgery performed by less experienced surgeons (P = 0.034). CONCLUSIONS: Treatment plan was changed in 16.3% of patients after vitreoretinal surgery. The risk of treatment plan changes was associated with the surgeon’s experience in vitreoretinal surgery and the type of surgery. These results should be considered when establishing standardized care plans for patients who require vitreoretinal surgery.
