At present, there are many students who do not meet the eyesight standard but want to join the army choose to realize their military dreams through myopia surgery, and the conscription requires conscripts to have myopia surgery at least half a year in advanceI'm here to answer for you today.
The recovery time after myopia eye surgery varies from person to person, in general, the eyes can be used normally about 3-5 hours after myopia eye surgery, and most patients can generally use their eyes normally the next day after surgery.
However, being able to use the eyes normally does not mean that the eyes are completely recovered, myopia surgery requires an incorporation in the eye, and the size of the incision is not the same for different surgeries, and the existence of the incision will reduce the biomechanical stability of the cornea, for the military, which requires strenuous exercise, strenuous exercise or body collision in the case of the eye has not completely healed may cause corneal flap displacement or other eye damage, so it is necessary to perform surgery at least half a year in advance, to reserve sufficient recovery time for the eye.
At present, there are three types of myopia surgeries for conscription: full femtosecond, half femtosecond, and full laser.
Instead of making an open corneal flap, a laser is used to shape the corneal matrix to be cut through a secondary interlayer blast of different depths inside the cornea, create a lens, and then remove the lens through an incision of about 3 mm.
Half femtosecond surgery begins with a femtosecond laser device to create a flip-open corneal flap and then uses an excimer laser to perform corneal resection. Since the excimer laser performs the corneal stromal cutting in an "ablative" manner, there will be a burnt smell during the procedure, and the incision of the corneal flap is about 18-20 mm.
The corneal epithelium is ablated directly by laser surgery, and although there is no incision left in the surgery, it takes a while for the corneal epithelium to recover naturally because the corneal epithelium is ablated during the surgery.
