Harvey Maurice Levy, who is registered at Highfield Hall Hotel, Mold, Clywd, was alleged to have claimed a sight test fee regarding a deceased patient.
The committee heard that Mr Levy also failed to adequately test the sight of several patients during domiciliary work in 2000.
In addition, Mr Levy was accused of using inadequate equipment and inadequate record-keeping when carrying out his work at the Coed Craig Residential Home in Colwyn Bay, North Wales, on August 31, 2001.
On September 17 2001, Mr Levy claimed a fee 'inappropriately' for testing the sight of the dead patient known as 'patient B', it was alleged.
Bradley Albury, counsel for the GOC, told its professional conduct committee: 'There is no doubt that patient B was dead. Mr Levy claimed a fee for testing the sight of patient B on that day, a day when patient B was already dead.
'Documentation includes the death certificate of patient B and documents relating to the sight test purportedly carried out on her, on a date when she was in fact deceased.'
Mr Levy, of Wimbourne, Dorset, also failed to 'adequately' test the sight of 22 patients at Tree Tops Nursing Home, Scarborough on September 5 2000, when he spent two hours at the home it was alleged.
Expert witness Geoffrey Roberson examined the records of sight tests which Mr Levy carried out at the home and told the committee 'I think a reasonable time to conduct an eyetest is about 20 minutes.'
The hearing, which is taking place in London, continues.
An optometrist faced a charge of serious professional misconduct at a GOC disciplinary committee hearing this week.
