Visual outcome of cataract surgery and its influencing factors for senile cataract in rural areas of Danzhou

Objective To investigate the visual outcomes of cataract surgery in senile patients in rural areas of Danzhou and its inf l uencing factors, and provide basis for the improvement of patients' visual function and quality of life. Methods A retrospective analysis on medical data of 692 senile patients undergoing cataract surgery in rural areas of Danzhou from January 2013 to December 2016 was carried out. Univariate logistic regression analysis and multivariate ordered logistic regression analysis were used to explore the inf l uencing factors. Results A total of 825 eyes in 692 senile cataract patients were enrolled,including 287 males (338 eyes) and 405 females (487 eyes). The postoperative corrected visual acuity of the left eyes was significantly higher than before surgery (Md:0.66 vs 0.12, Z=56.317, P< 0.01), and the postoperative corrected visual acuity of the right eyes was also significantly higher than before operation (Md:0.63 vs 0.15, Z=42.816, P< 0.01). Univariate and multivariate logistic regression analysis showed that ageOR(95% CI):1.418(1.347-1.526), history of hypertensionOR(95% CI):2.826(2.036-4.915), history of diabetesOR(95% CI):1.638(1.526-1.871), coronary heart diseaseOR(95% CI):1.509 (1.437-1.618), postoperative complicationsOR(95% CI):3.674(3.175-7.062), abnormal preoperative intraocular pressureOR(95% CI):3.082(2.528-5.873), abnormal pupil conditionOR(95% CI):1.614(1.506-1.835) and receiving extracapsular extirpation with small incisionOR(95% CI):1.381(1.329-1.536) were independent risk factors inf l uencing the visual outcomes of cataract surgery in senile patients. Conclusion Eyesight status of aged cataract patients in rural areas of Danzhou improve significantly after surgery. Various risk factors affect the surgery outcome, so preventive measures should be taken in order to improve the visual function and quality of life of these patients.
