Visual outcomes after cataract surgery in monocular compared to binocular patients: a case–control study
Purpose We aimed to identify ocular comorbidities and reasons of blindness in monocular patients and to compare visual outcomes of cataract surgery between monocular and binocular patients. Methods A single-center case–control study was conducted between November 2011 and May 2019 to compare consecutive series of patients needing cataract surgery in Strasbourg University Hospitals, France. Cases were patients with permanent monocular vision loss. Controls were binocularly sighted patients. All patients underwent cataract surgery using phacoemulsification technique. Chart analysis included demographic data, medical history, and surgical determinants data. Student's t tests and Fisher’s exact tests were the main methods used for statistical analysis. Results Each group included 80 patients. The mean age at the time of surgery was significantly higher in monocular than binocular patients (77 vs. 71 years, p < 0.001). Thirty-two monocular patients (40%) had ocular comorbidities, compared to only 19 (23%) in the control group (p < 0.05). The leading cause of monocular status was amblyopia caused by strabismus (22 patients, 27.5%). Age-related macular degeneration, open-angle glaucoma, and diabetic retinopathy were the three main ocular comorbidities that were observed in the monocular group. Monocular patients had significantly lower visual acuity than the control group (p < 0.01) before and after cataract surgery. Conversely, improvement in visual acuity after surgery was not statistically different between groups (p = 0.054). There was no statistically significant difference in the rate of surgical complications between groups (p = 0.622). Conclusions This study illustrates that cataract surgery in monocular patients is not more complicated than in binocular patients, but that it is significantly delayed..
