ABSTRACT
Purpose To compare the postoperative outcomes and management of uncomplicated cataract surgery seen on postoperative day 0 (POD0) versus postoperative day one (POD1). Methods A retrospective cohort study of patients who followed up within 0-14 days of their uncomplicated surgery (current procedural terminology code 66984) from December 2018 to March 2020. Those who had perioperative complications, those who had combined glaucoma filtering surgery as well as other minimally invasive glaucoma surgery (MIGS) procedures, and those who did not complete their first two follow-up visits within 14 days of their surgery were excluded. Visual acuity (VA), intraocular pressure (IOP), post-operative interventions, and complications of the first and second postoperative visits were collected. Results Of the 665 participants studied, the mean (standard deviation) age was 68 (11) years old and 60% were female (n=304) with a mean (SD) pre-op logarithm of the minimum angle of resolution (logMAR) VA of 0.715 (0.625). About one-third (32%) of patients were seen on POD0. Compared to POD1, a higher percent of patients with glaucoma were seen POD0 (23% vs 14%; p = 0.008). The mean VA on POD0 was 0.840 (0.653), which was significantly worse than the mean VA of 0.539 (0.599) on POD1 (p<0.0001). There was no significant difference in VA by the second post-op visit. IOP did not significantly differ between POD0 and POD1 groups at the first post-operative visit. The most common changes in the post-operative drop regimen were related to IOP and inflammation control. The rate of interventions did not significantly differ between groups (p>0.1). Patients who received intervention on POD0 were not seen significantly sooner at the next follow-up visit compared to those seen on POD0 without undergoing an intervention. The incidence of an IOP spike greater than 30mmHg on POD0 or POD1 was not significantly different between patients with and without underlying glaucoma (overall p = 0.2020; with glaucoma p= 0.1238; without glaucoma p=0.999). Those with a history of glaucoma were not more likely to receive intervention to lower IOP on POD0 versus those seen on POD1 (p = 0.999). Conclusion It can be difficult to evaluate patients the day after their uncomplicated cataract surgery, and it is difficult to predict which patients may have post-operative complications. Our study shows no significant changes in management for patients seen on POD0 compared to POD1. Surgeons can expect significantly better visual acuity on POD1, but otherwise, post-operative outcomes were similar between patients seen on POD0 and those seen on POD1. Surgeons may offer the option of a POD0 visit for patients who underwent uncomplicated cataract surgery.
