First, read the English article below.

If your cat has been diagnosed with a medical condition that requires special treatment, medication, or other interventions, make sure that you follow the veterinarian's instructions. If your cat's blindness is related to a medical condition, it will not improve until she is cured. Contact your veterinarian immediately if your cat's condition worsens or does not improve despite treatment. Be aware that some forms of blindness are not reversible even with medical interventions. Your cat may remain blind for the rest of her life, but she can still have a happy life. Your cat is still normal. Even though she has gone blind, she will still want to do everything that a cat likes to do, like playing. While buying toys, look for cat toys that are made specifically for blind cats. Also, shift from sight-based games to sound-based ones, such as "follow-the-noise." Anything that crinkles, crackles, resounds or can be tapped can serve as a new source of entertainment. Try buying toys that squeak like a mouse or chirp like a bird. Your cat might like to play follow the noise with those types of toys. as you always have. Groom your cat regularly, feed your cat nutritious food, provide occasional treats, and take your cat to a vet for regular check-ups. Pay special attention to your cat's nose and ears, as these senses now make life easier for your cat.  Keep your cat's food and water in the same place they have always been kept. Consider adding a second litter box to make it easier for your cat to get to the bathroom in time. It may take her longer to find the box now that she is blind.
