Patients after cataract surgery may experience photophobia or tearing, dry eyes and other eye surface irritation symptoms. The main reasons for the above symptoms may be twofold: a. After cataract surgery, the original cloudy lens suddenly becomes a highly transparent artificial lens, and there is a significant change in the amount of light intake to the eyes. Many elderly people may not be able to adapt to the sudden change quickly, so they may feel harsher light in daily light and have photophobia. In fact, this is a manifestation of the body’s inability to adapt to the surgical changes quickly after the surgery, and the photophobia and discomfort will gradually ease as the body adapts.
Second, because the surgical process will also cause damage to the corneal tissue surgical incision, it may affect the nerve endings in the cornea, and may also appear postoperative dry eye and other manifestations. Dry eye itself may also cause a certain degree of photophobia, which can be relieved by using drugs such as artificial tears. As the nerve endings are repaired later, the discomfort can be gradually relieved over time, which may take a few weeks or months.
