Any surgery has risks. After hemi-femtosecond surgery, patients can have hazards such as glare and night vision disorders, dry eyes and cone cornea.
1. Glare and night vision disorders: If the patient’s myopia is high, such as more than 1,000 degrees, about 80% of the patients can have night glare, while a few patients can have night vision problems, mostly caused by the surgery cutting more corneal tissue.
2. Dry eye: Semi-femtosecond surgery needs to cut patients’ corneal tissues, which may hurt the corneal nerves and reduce tear secretion, so patients may experience dry eyes, foreign body sensation, and other dry eye discomfort symptoms.
3. Conical cornea: If the patient’s cornea is thin or the degree of myopia is high, the patient may have a conical cornea, i.e., a bulging cornea, after the surgery.
It is recommended to follow the doctor’s instructions to take care of the patients after the hemi-femtosecond surgery, regular checkups, and timely consultation after discomfort occurs.
