Optos, the eyecare company that changed its chief executive last year, took an exceptional charge of $4.9m to cover the costs of refocusing on its core retinal imaging business.

This led the Dunfermline-based company to make a pre-tax loss of $4.86m in the six months to March 31, compared with a pre-tax profit of $1.85m in the same period last year.

Revenue was flat at $47.8m, down from $48.9m, which the company said reflected its focus on pay-per-patient revenues and reduced emphasis on capital sales .

Roy Davis, the new chief executive, said good progress was being made on strategic changes and the company’s headcount had been reduced by 20 per cent.

Optos said its biggest market, North America, suffered from adversely affected consumer confidence, leading to lower footfall into US optometry practices and less use of its devices, though this had stabilised at a lower level.

Mr Davis said: “I believe the steps we are taking and the renewed focus on our core optometry business will drive improved business performance in the medium term.”
