Multiple lattice with hole. Guide me.

I had done laser treatment for retinal lattice with hole in both eye , the treatment is divided into partly laser treatment.Firstly doctor done retinal laser barrage c green 40 where i used to get some new floaters after the treatment,then i asked to him why new small dark floaters is comming he said some cells are released that why dark new floaters.but no flashes of light. The second laser was done after 10 days and treatment was retinal laser prophylactic c green 40 after the second treatment after 2-3 days i used to get floaters and flashes of light more in left eye where more lattice with holes are present and more laser is directed. I contacted the near opthomologist for floaters he said it is normal to have floaters and did not cause any serious issue. But my concern is why flashes of light at the corner of the eyes is seeing in left eye. Is this flashes of light are cause for concern. Please guide me.
