The overall CSC at best corrected visual acuity (BCVA) &lt;3\/60, &lt;6\/60, and &lt;6\/18 in the Indian population was 93.3% (95% confidence interval [CI]: 91.5\u201394.7), 88.9% (95% CI: 86.5\u201390.9), and 72.6% (95% CI: 69.1\u201375.9), respectively. CSC was highest in the north and lowest in the northeast administrative zone at all BCVA cut-offs. Khera district had the highest CSC at BCVA &lt;3\/60 (99.1%) and &lt;6\/60 (97.9%), whereas Kapurthala district had the highest CSC at &lt;6\/18 (88%). Nalbari district had the lowest CSC at BCVA &lt;3\/60 (78%) and &lt;6\/60 (70.2%), and Nayagarh had the lowest CSC at &lt;6\/18 (45.6%). Overall, males had higher CSC than females. Gender variation was highest in Thoubal at BCVA &lt;3\/60 (18.7%) and &lt;6\/60 (19.2%).
