From: Glaucoma following congenital cataract surgery – the role of early surgery and posterior capsulotomy
Kaplan-Meier plots of glaucoma free survival after surgery within 7 months – Posterior Capsulotomy (PC) and no PC. To examine whether PC was a risk factor for AG after adjusting for timing of surgery, a plot was constructed comparing PC vs no PC in eyes operated on before 7 months only. The survival plot is supportive of the statement that intact PCs may be associated with lower risk of AG. The observed difference is not statistically significant but this is not surprising given that only 3 patients operated on within 7 months had their PC intact.
