Variable	Congenital cataract	Age-related cataract
Sample size	65	13
Sex ratio (male%)	58.46% (38/65)	46.15% (6/13)
Ratio of bilaterality	72.31% (47/65)	100.00% (13/13)
Age when sampled (mean ± SD, years)	3.89±2.34	70.46±3.93
Major surgical procedures	I/A + IOL + PCCC + A-Vit† (84.62%, 55/65)	Phaco + IOL‡ (100.00%, 13/13)

Age distribution of the congenital cataract group: 7 patients (≤1 years old); 8 patients (1–2 years old); 10 patients (2–3 years old); 13 patients (3–4 years old); 11 patients (4–5 years old); 5 patients (5–6 years old); 11 patients (>6 years old). ^†, I/A + IOL + PCCC + A-Vit = lens aspiration with IOL implantation, posterior continuous curvilinear capsulorhexis and anterior vitrectomy; ^‡, Phaco + IOL = cataract phacoemulsification and intraocular lens implantation.
