Barrage Laser Treatment. Are dangerous?

I had undergone barrage laser for multiple lattice with hole in both eye for 2 times. First barrage treatment for both eyes was done on 15/07/2020 partly and other part treatment on 24/07/2020. But i used to have some flashes of light at the corner of the left eye where the power is high as well as lattice with hole is also more so doctor had done more treatment on the left eye compared to right eye. Is it normal to have flashes of light at the corner of the eyes and some floaters with some small pigment dark floaters included. Doctor told me new flaoters are seen due to some cells may relase after treatment and it usually will go in 15-30 days. Is this floaters and flashes of light are dangerous? Please guide me.
