Glare after femtosecond surgery?

After laser surgery, the phenomenon of glare appears in myopic eyes, which may be: (1) the traditional laser cutting light area is small, which can cause postoperative glare: if the laser treatment light area is small, when the pupil diameter exceeds the treatment light area under dark light, the glare symptom will appear.

(2) Large pupil diameter is prone to postoperative glare, everyone's pupil size is not the same, too large pupil diameter, even if the use of large light area cutting treatment is still difficult to completely cover its dark pupil, therefore, this kind of crowd had better not choose myopia correction surgery.

(3) The higher the myopia degree is, the more cornea will be cut, the deeper the "depression" will be formed on the corneal surface, and the larger the slope will be.
