Abstract
Aim: To investigate the aspects of spectacle correction of vision-impairing refractive error and presbyopia in
those aged >40 years in Timor-Leste.
Method: A population-based cross-sectional survey with cluster random sampling was used to select 50
clusters of 30 people. Those who had uncorrected or undercorrected refractive error (presenting acuity worse
than 6/18, but at least 6/18 with pinhole), uncorrected or undercorrected presbyopia (near vision worse
than N8), and/or who were using or had used spectacles were identified. Dispensing history, willingness to
wear and willingness to pay for spectacles were elicited.
Results: Of 1470 people enumerated, 1414 were examined (96.2%). The ‘‘met refractive error need’’ in the
sample was 2.2%, and the ‘‘unmet refractive error need’’ was 11.7%. The ‘‘refractive error correction
coverage’’ was 15.7%. The ‘‘met presbyopic need’’ was 11.5%, and the ‘‘unmet presbyopic need’’ was
32.3%. The ‘‘presbyopia correction coverage’’ was 26.2%. Lower correction coverage was associated with
rural domicile, illiteracy and farming. Of the sample, 96.0% were willing to wear spectacles correcting
impaired vision. Of these, 17.0% were willing to pay US$3 (£1.52, J2.24) for spectacles, whereas 50.2%
were unwilling to pay US$1 (£0.51, J0.75). Women and rural dwellers were less likely to be willing to pay at
least US$1 for spectacles.
Conclusion: Refractive error and presbyopia correction coverage rates are low in Timor-Leste. There is a
large need for spectacles, especially for elderly and illiterate people, farmers and rural dwellers: those least
able to pay for them. An equitable cross-subsidisation spectacle system should be possible.
