NHS Grampian is coming under increasing pressure to get eye clinic appointments back to Moray.
Patients are currently facing lengthy journeys to Aberdeen Royal Infirmary to be seen by consultants.
Next week MSPs Richard Lochhead and Douglas Ross will team up to press health bosses on when staff shortages can expect to be resolved.
Concerns about the declining level of eye care at Dr Gray’s Hospital in Elgin were raised in the Scottish Parliament late last year.
And Mr Lochhead is eager to see the clinics returned to their full capacity to deliver services for residents in the area as soon as possible.
He said: “I’m aware that the lack of a consultant in Elgin has caused real problems for some elderly patients who have found the long journey very difficult.
“The recent assurances offered by the chief executive of NHS Grampian that an eye clinic will return to Dr Gray’s are very welcome but I know that patients are looking for more clarity about the health board’s plans.
“While I do appreciate the challenge with provision at Dr Gray’s is often the difficulty in recruiting staff to key posts, I will be pressing him for details as to how soon we can expect to see eye clinics reinstated locally.”
Mr Ross also intends to get an update on the treatment available for cancer patients during the meeting.
He added: “A growing concern for all in Moray is the staffing levels at Dr Gray’s Hospital and the number of patients who are having to make journeys, taking up to perhaps a whole day, to attend clinic appointments in Aberdeen which often only last for a few minutes.
“Others have been waiting a significant period of time to receive treatment due to the lack of medical staff locally and I am sure we will have a full discussion on this.”
An NHS Grampian spokeswoman said: “We regularly meet with MPs and MSPs. An invitation went to Moray and Highland and Islands MPs and MSPs to discuss any ongoing issues at an informal closed meeting next week.”
