Crystal implantation surgery, i.e. artificial crystal (ICL) implantation surgery, can be used to correct refractive errors, etc. After the surgery, you need to pay attention to resting with your eyes closed, protecting your eyes, using your eyes reasonably, and avoiding driving at night. In the first few hours after IOL implantation, you should avoid touching the eye area with your hands. If you experience photophobia, tearing, or a foreign body sensation in the eye, you should avoid wiping your eyes directly with tissue paper, try to rest with your eyes closed, and avoid rubbing or rotating your eyeballs. In the long-term life after IOL implantation surgery, one should pay attention to avoiding eye trauma, impact, etc., and preventing foreign objects from entering the eye; pay attention to reasonable eye use in daily life, avoiding excessive eye use that leads to eye fatigue; part of the highly myopic people may have symptoms such as glare, so they should avoid driving at night. It is recommended that IOL implantation patients should follow the doctor’s instructions to promote eye recovery after the surgery, and should consult the doctor in time if they have any symptoms of discomfort.
