Introduction
Blurred vision after semi-Femto surgery may be due to the cornea not having fully recovered post-operation. It is recommended to visit an ophthalmology department at a hospital for a detailed examination, as laser eye surgery for myopia works by altering corneal thickness to achieve its therapeutic effect. Generally, there's no need to be overly anxious—follow your doctor's instructions regarding eye drops and attend regular follow-up appointments. Vision typically begins to improve gradually within a few days and eventually returns to normal.
Blurred vision after a semi-Femtosecond procedure may be due to incomplete recovery of the cornea. It is recommended to visit an ophthalmology department at a hospital for a detailed examination, as laser eye surgery for myopia works by altering corneal thickness to achieve its therapeutic effect.
In the first few hours after the semi-Femtosecond surgery, patients may experience tearing, light sensitivity, or a foreign body sensation in the eye. A small number of individuals might feel mild eye pain or subconjunctival hemorrhage after surgery; these are normal postoperative phenomena that will resolve spontaneously.
Some people may experience blurry near vision. Younger patients usually recover within about half a month, but for older individuals or those with poor accommodative ability—such as patients over 40 years old—the duration may be longer. They may need to hold books or phones farther away or enlarge text when reading. Generally, symptoms gradually disappear within around two weeks, though in some cases it may take three to four weeks, as the eye's accommodative function recovers progressively.
There's usually no need for excessive concern. Follow your doctor’s instructions regarding eye drop usage and attend regular follow-up appointments at the hospital. At home, ensure adequate rest, get sufficient sleep, minimize screen time on phones and computers, avoid getting dirty water in the eyes, and prevent any eye injuries. Vision typically improves gradually within a few days and eventually returns to normal.
If postoperative vision is lower than expected—for example, if the preoperative prediction was 1.0 but actual postoperative vision is only 0.8, 0.6, or even lower—it is important to consult a doctor to determine the cause. This could be due to undercorrection or overcorrection during surgery, or complications developing after the procedure.
