After cataract surgery, it is best for patients not to touch oil smoke for a month, so it is best not to cook. Cataract is a common eye disease among middle-aged and elderly people, which may cause vision loss and usually needs to be treated by surgery. It is better for patients not to touch the oil smoke within one month after the surgery because the oil smoke stimulation is not conducive to the healing of the surgical incision, and it is also easy to cause dry eyes and other discomforts, so it is better for patients not to cook within one month after the surgery. Generally speaking, more than one month after the operation, the incision site has healed relatively well, and the discomfort of the eye has basically subsided. At this time, it may not have a great impact to do some normal household chores, such as cooking. Specifically, you can also determine the time for cooking after the follow-up examination in January after the operation by the physician to determine the recovery situation. It is recommended that patients go to the ophthalmology department of a regular hospital for consultation and post-cataract care under the guidance of a doctor.
