Around this time, Charlotte was beginning to suffer a painful toothache, which made many of her teeth fall out. She was even more worried about her father's blindness. On 19 August 1846, Charlotte went to Manchester with her father to see an eye surgeon, William James Wilson. Wilson performed the operation on 25 August. The next day, Charlotte described it to her friend Ellen in a letter. Wilson had been helped by two other surgeons. The operation had taken about 15 minutes. Charlotte wrote, "Papa is now confined to his bed in a dark room and is not to be stirred for four days - He is to speak and to be spoken to as little as possible". "Depressed and weary (tired)", Charlotte began writing "Jane Eyre".
