Looking for Kids Paediatric Eye Specialist (Ophthalmologist) ASAP

Hi my child has a severe astigmatism for her left eye, she can’t see things from one angle and kept saying her vision is extremely blurry. I am very worried despite we have seen doc in KKH but her left eye’s condition deteriorated drastically within 3 months from her first visit. The recent one was just last week but the doc (not the same one from the first visit) didn’t do any eye-patching for her left eye. Thus I want to ask for some good recommendations for a PD Ophthalmologist ASAP for a 2nd opinion, does any mummy know? Pls advise me. Thanks!
