Gardai investigating the aggravated burglary and assault on Tom Niland have been carrying out searches near his Sligo home on Sunday.
The 73-year-old remains on life support after he was critically injured in the attack last month.
He was watching television at his home in Skreen on January 18 when three masked men forced their way into his home and viciously assaulted him at around 7pm.
Tom was left with serious head and upper body injuries and he has been in a critical condition at Sligo University Hospital since.
Gardai said that progress continues to be made in their investigation into the incident as they conducted searches around the vicinity of the pensioner's home on Sunday.
The searches were carried out he N59, between Doonflynn, Dromore West and along the route leading up as far as Lough Easkey.
According to the force, "significant evidence" has already been recovered along this route and the searches on Sunday were aimed at identifying and recovering "any other material of evidential value to this investigation".
The Sligo Divisional Search team, the Garda Mounted Unit, Garda Dog Unit, Garda Water Unit, Garda Air Support, local Civil Defence and community volunteers all took part in the pursuit on Sunday.
Superintendent Mandy Gaynor from Sligo Garda Station said she was "utilising every resource at my disposal in this investigation".
She said: "I am overwhelmed with the significant level of community support and information being received by the investigation team at Sligo Garda Station.
"I am satisfied that progress continues to be made with the investigation to date. We are following specific lines of enquiry, taken numerous statements, secured hours of CCTV footage and continue to liaise with Forensic Science Ireland (FSI).

"I am confident there are still people out there who know who was involved in this aggravated burglary and serious assault on an elderly man in his home.
