Clinical Characteristics and Surgical Safety in Congenital Cataract Eyes with Three Pathological Types of Posterior Capsule Abnormalities

Table 4

The comparison of surgical complication rates between the eyes with and without PCA.

	With PCA (n, %)	Without PCA (n, %)
Capsule shrinking	0	0.4	—
IOP rise	0.4	0	—
Posterior capsule tear	0.4	0.8	0.659
VAO	1.3	0	—
Posterior synechia of the iris	2.9	4.7	0.397
Drug toxic keratitis	3.4	5.4	0.340

PCA, posterior capsule abnormality; IOP, intraocular pressure; VAO, visual axis opacity; chi-squared test.
