At present, the technology of full femtosecond laser myopia surgery is more mature and the surgery is safer, but patients can still suffer from complications such as dry eye, secondary glaucoma and secondary cone cornea after the surgery.
During the process of full femtosecond laser surgery, corneal incision needs to be made, which will cut off part of the corneal sensory nerve fibers, causing patients’ postoperative corneal hyperalgesia and reduced reflex tear secretion, which may result in patients’ dry eye syndrome.
Because the thickness of the patient’s cornea may become thin after full femtosecond laser surgery treatment, if the residual corneal thickness is unable to tolerate the pressure effect inside the eyeball, the patient may develop cone cornea, i.e. corneal bulging.
After full femtosecond laser surgery, patients usually need to use hormone eye drops to reduce postoperative inflammatory reaction and avoid scar formation in the cornea, but the long-term use of hormone drugs may lead to secondary glaucoma.
It is recommended that myopic patients consult a hospital in a timely manner to assess their condition and follow the doctor’s instructions for treatment.
