Soft Contact Lens (SCL) use all over the world is still increasing. Ocular surface inflammatory reaction is the most common risk of using SCL. Currently, the standard used to assess this complication is the Efron Degree System (EDS), but it has high variability due its subjectivity. ImageJ gives more objective result with conjunctival vasodilation and vascular density assessment, so that complication management can be given earlier.
Purpose: Evaluate the suitability of SDE with ImageJ analysis in assessing conjunctival hyperemia in SCL use within 2 weeks.
This is a paired prospective analytic study. Subjects with myopia who have not used SCL routinely before were instructed to use SCL for 14 days. Conjunctival inflammation were assessed with slit lamp examination before, at day 7, and day 14 of using SCL. Slit lamp pictures were analysed with EDS and ImageJ to be compared.

Conjunctival inflammation degree evaluation was done with taking picture of conjunctiva using slit lamp by lead researcher. Picture was taken on day 0 (before using SCL), day 7, and day 14 of wearing SCL. Pictures then were analyzed with Efron Degree System (EDS) by 2 evaluators (both were ophthalmologist consultants) and with ImageJ application by lead researcher. ImageJ analysis was done to decide conjunctival vascular diameter and density. EDS evaluator did not know the results of the assessment with ImageJ and vice versa.
