Nd:YAG Capsulotomy after Phacoemulsification in Vitrectomized Eyes: Effects of Pars Plana Vitrectomy on Posterior Capsule Opacification

Figure 4

Cox proportional hazards model. Surgical option was identified as a risk factor that influenced the time interval from cataract surgery to capsulotomy. The CV group had a higher risk of a shorter Nd:YAG capsulotomy free survival time than the CA group ((c), hazard ratio (HR) = 1.337; 95% confidence interval (CI) 1.100–1.625; 𝑃=0.003). Combined surgery and sequential surgery were associated with an increased risk of a shorter Nd:YAG capsulotomy free survival time ((d), HR = 1.304; 95% CI; 1.007–1.688; 𝑃=0.44, HR = 1.361; 95% CI = 1.084–1.709; 𝑃=0.008, resp.). The CA group showed a longer Nd:YAG capsulotomy free survival than the CV group (a) and both the C-CV and S-CV groups (b).
