Yes, these symptoms suggest your mother may be having an allergic reaction to sertaconazole (the active ingredient in the cream). Please have her stop using the medication immediately. Gently rinse her eyes and face with cool water to remove any residue, and advise her not to rub her eyes. An over-the-counter oral antihistamine like cetirizine can help reduce the itching and swelling. Please consult a doctor or an eye specialist promptly for a proper evaluation to ensure her eyes are safe. Avoid applying any other creams to the area until advised by a physician.
