Cataract surgical coverage among people with pin hole visual acuity < 3/60, <6/60 and <6/18 were 86.1%, 80.6% and 56.2% respectively. However cataract surgical coverage among eyes having cataract and pin hole visual acuity as < 3/60, <6/60 and <6/18 were 72.8%, 65.6% and 41.9% respectively.
Most of cataract surgeries in Purbi Singhbhum, Jharkhand 89.3% were surgeries with intra-ocular lens implantation.
Majority visual outcome after cataract surgery were very good, 60.8% people had presenting visual acuity >6/12 in operated eye. However 22.9% had visual acuity <6/18 in operated eye and 11.6% had PVA < 6/60. Among those whose visual acuity was better than 6/60, the most important cause was Ocular comorbidity 42.4%. Those patients whose post-operative PVA < 6/60, the most important cause was existing pre-operative Ocular comorbidity 50.9% Other causes of poor outcomes were Uncorrected refractive error 24.5%.
Out of all people having bilateral pinhole visual acuity <3/60 due to cataract, in people aged ≥ 50 years most important barriers for cataract surgery were Cost (40%), Cannot access treatment (31.4%), Need not felt (14.3%) and Fear (8.6%).
Presenting visual acuity < 3/60 in better eye
Presenting visual acuity < 6/60 – 3/60 in better eye
Presenting visual acuity < 6/18 – 6/60 in better eye
Presenting visual acuity < 6/12 – 6/18 in better eye
Presenting visual acuity <6/18-3/60 in better eye
Presenting visual acuity < 6/18 in better eye

Cataract Surgical Coverage (Person) indicates how many persons received cataract surgery (one or both eyes) among all who were bilaterally pinhole blind due to cataract.
The numerator includes persons with one operated and one pinhole blind eye and persons with bilateral (pseudo) aphakia. The denominator includes the numerator, plus persons bilaterally pinhole blind due to cataract. Besides this, the indicator can also be calculated separately for PinVA <6/60 and <6/18.
Cataract Surgical Coverage (Eye) measures the proportions of eyes pinhole blind due to cataract, which have been operated so far.
The numerator includes all (pseudo) aphakic eyes. The denominator includes the numerator, plus eyes pinhole blind due to cataract. Besides this, the indicator can also be calculated separately for PinVA <6/60 and <6/18.
