Alanna Quinn Idris has said she feels "let down" with the sentence given to the people involved in her attack on 30 December 2021, which left her blind in one eye.
On Monday, Josh Cummins was sentenced to five years imprisonment with the final two years suspended, having admitted to assault causing serious harm to Ms Quinn Idris, and assault on her male friend.
Earlier this year, Darragh Lyons was jailed for four and a half years for his role in the attack.
Speaking to Prime Time, Ms Quinn Idris said she didn't think the two who have been sentenced have seen the consequences of their actions.
"I feel really let down. It's hard enough to have to go through the pain of this, go through the suffering of this, go to court, go through everyday life now as this, you know, like, I am permanently disfigured... I have to suffer through that for the rest of my life."
"It's just a slap in the face. Not only for me but for everybody else that has gone through something similar to me like, and not gotten justice," she added.
Having been through two court proceedings since the attack, Ms. Quinn Idris said she’s frustrated at the process.
"It's just really frustrating having to do it and then not being super thrilled with the results of it... it's just tedious. It's just another thing that I feel like I have to go through because of these people."
"I'm going through a lot more than they’re going through," she added.
Four people were involved in the attack. Ms Quinn Idris said prior to it, she was in a very positive place personally, having previously struggled with mental health issues.
"I was actually at a point where I was delighted - genuinely - like couldn't have been happier."
"I had all these plans and everything, and then it was just taken... the life that I had planned and for myself was just taken from me entirely."
Speaking to Prime Time, Ms Quinn Idris recalled the night of the attack, when she and her friend were approached by Cummins, Lyons and others outside the house of another friend in Ballyfermot.
She said she was punched in the face and was hit with the saddle of a scooter when she tried to intervene to stop people attacking her friend.
In the sentencing on Monday, the judge in the case against Josh Cummins noted that neither of the two people sentenced thus far were the individual who used the saddle to strike Ms Quinn Idris and cause the "devastating injuries" she has suffered.
The judge noted that Cummins took a hurl to scene of the attack and "utilised that in a vicious manner" against the male friend of Ms Quinn Idris, in the process showing "no care for physical welfare or safety of anyone else."
The judge described the injuries sustained by Ms Quinn Idris as "serious and life changing," and said she displayed "immense courage" in attempting to intervene in the attack, and in giving a victim impact statement to the court.
In response to questions from Miriam O’Callaghan, Ms Quinn Idris recalled what she remembered of the attack.
"I just remember feeling like just my face was just like, it's like it was numb, you know, like when you go to the dentist, it doesn't feel normal. It feels like part of your body's not there," she said.
"I just remember screaming and vomiting and there was all lights flashing around me and everything and so many people. And I just didn't have a clue what had happened."
The attack has left Ms Quinn Idris with devastating injuries. She said the first time she saw the damage to her eye, she was hysterical.
"I had to open my eye like with both of my hands because it was so swollen. I remember looking at it and it was just destroyed. I didn't know what I was looking at.... I just was in hysterics. I just remember screaming basically the whole hospital down."
Despite multiple surgeries, Ms Quinn Idris has permanently lost the vision in her right eye.
"I'm always thinking like, who could I have been? I was only 17... so I just feel like it did change like who I am and who I was meant to be."
Despite having the strength to "go on" after the attack, Ms Quinn Idris says she still struggles.
"It's never going, you know, to go back the way it was... I don't want to say I'm okay."
"It's not something I'm over in any way at all...it's just, it's really hard."
Miriam O’Callaghan’s interview with Alanna Quinn Idris features on the Thursday 12 December edition of Prime Time, broadcast on RTE One at 9.35pm.
