Building work is due to start on an expansion of Pinderfields Hosptial under a controversial shake-up of services.
An eye clinic and offices will he housed in a new unit which is being built to free up space in the existing hospital buildings for 88 extra beds.
The beds are being provided to cope with more patients after accident and emergency services are centralised at Pinderfields.
Critically ill and injured patients from Dewsbury will be transferred to Pinderfields as Dewsbury’s A&E unit will be downgraded to an urgent care centre treating minor ailments.
Dewsbury will also lose its consultant-led maternity unit as complex births are transferred to Pinderfields.
The plan sparked fears that Pinderfields could struggle to cope with more patients and people would have too far to travel for treatment.
But health campaigners lost a battle to halt the plans in July when the secretary of state for health Jeremy Hunt ruled that the changes were in the best interests of patients.
Caroline Griffiths, director of planning and partnerships at Mid Yorkshire Hospitals Trust, said: “It is planned that all urgent medical and surgical care and all complex surgery will be carried out at Pinderfields by 2017, with an extra 88 beds created at Pinderfields Hospital to accommodate additional urgent and emergency care.”
The new clinical support unit is scheduled to open in early 2015.
