Analysis of influencing factors of tear film stability in elderly patients with age-related cataract after surgery
Objective To analyze the influencing factors of tear film stability in elderly patients with age-related cata-ract after surgery,and provide reference for improving the prognosis of elderly patients in clinical practice.Methods The clin-ical data of 140 elderly patients with age-related cataract who received surgical treatment in Changhai Hospital Affiliated to Na-val Medical University from June 2021 to June 2023 were retrospectively analyzed.According to the time of tear film rupture at the 3-month follow-up after surgery,patients were divided into stable tear film group and unstable tear film group.Their clini-cal baseline data and surgical conditions were recorded.Univariate and binary logistic regression analysis was performed to ana-lyze the related factors affecting postoperative tear film stability in patients with age-related cataract.Results There was no statistically significant difference in age,disease duration,lens nucleus hardness,surgical incision location,ultrasound cumula-tive energy release,comorbidities of heart disease,hypertension,meibomian gland dysfunction and pterygium between the two groups(P＞0.05).There were significant differences in phacoemulsification time,severity of disease,diabetes mellitus,sin-gle-day visual terminal use time,conjunctival relaxation grade and palpebral lipid viscosity grade between the two groups(P＜0.05).Multivariate analysis showed that the conjunctival relaxation grade(OR=5.48),palpebral lipid viscosity grade(OR=3.57),phacoemulsification time ≥ 20 min(OR=2.70),severity of disease(OR=1.78),diabetes mellitus(OR=4.55),and single-day visual terminal use time ≥2 h(OR=2.31)were the influencing factors for tear film instability after surgery(P＜0.05).Conclusion The conjunctival relaxation grade,palpebral lipid viscosity grade,phacoemulsification time≥20 min,severity of disease,diabetes mellitus,and single-day visual terminal use time ≥2 h may be the influencing factors for postoperative tear film instability in elderly patients.
