Welcome to HCM.
In any Retinal procedures, the earlier the intervention, the visual prognosis is better. And in your case, 2 months with RD(retinal detachment
) is something which should be kept in mind.
You have not mentioned whether your central part of the nerve
( the macula )was also detached in the process.
Post operatively, we can wait for 3-6 mths period for the eye to recover functionally.
So to be frank, you have to wait for a couple more months for the retina to settle down and recover for the final outcome. Your vision might get better compared to now in this period, or if the macula was involved the prognosis is not as expected.
