Lucentis in left and right eye. That.

Dear Doctor, We are getting consultation for my mothers diabetic retinopathy as the OCT report stated 650 um amd 450 um in left and right eye respectively. She got treated with one injection each of Lucentis in both eye with current OCT report showing 238 um and 290 um (after 3 weeks and 1 week of injection) for left and right eye respectively. Post soing the FFA doctor has recomended for focal laser for left eye for further removing some elements and ensuring that frequent injections can be prevented. Let me know how safe is focal laser treatement over and above injections and if we should go for it or wait for anothee oct report after a montj and see the status and then take a call on how to proceed. I have heard that focal laser has some risks of loss of vision and her vision has slightlu improved post the injections and we dont want to risk that.
