OK so very similar to us.
Ds had lens removed at 3 weeks. For 4 weeks he had drops 4x a day and once those were finished he was fitted with a contact lens. Initially we went into the hospital each time it fell out or needed replacing (monthly) but I soon got fed up with that and learned to insert and remove myself. I've never worn lenses but it is OK doing it. I won't say easy but OK.
To ensure vision develops in the cataract eye we patch (occlusion therapy) this started at 1 waking hour per day and increased to 6 hours per day eventually. Basically you stick the patch over the good eye and go about your daily business- at first they will probably sleep as soon as the patch goes on because they can't see and getting the 1 hour can be really frustrating but as vision develops this gets easier.
We have eye pressure eye health and vision checked at the hospital regularly, at first this was monthly and then after about a year reduced to once every 3 months.
Ds is now 3 and as I said previously is doing really well, can see the top two lines on the opticians eye chart and eye health is great. He does great with his patch on but we do take it off if he's doing physical activity e.g. soft play, football, as that's hard without some binocular vision.
Hospitals do differ, some use daily lenses or recommend daily removal, some patch more or less than we do, some use differing drops regimes.
Wishing you the best of luck. At 3 years out I am very chilled about all of this and my ds takes it in his stride, but I found it incredibly hard when we first found out.
As I said previously I would highly recommend the Facebook group which is brilliant and has saved my sanity many a time.
