Can my vision worsen again after surgery? Is an enhancement possible?
If vision decreases after surgery, it is most commonly due to myopic regression or dry eye. Myopic regression occurs when changes in the cornea lead to a partial return of nearsightedness and is typically identifiable within days after surgery. Vision changes related to dry eye are more common and may develop due to postoperative dryness, lifestyle factors, or environmental conditions. These symptoms can usually be improved with proper dry eye management and care. If necessary, enhancement options may be considered depending on the amount of remaining corneal tissue. These may include procedures such as LASEK or Implantable Collamer Lens (ICL) surgery. Additionally, presbyopia (age-related difficulty with near vision) is not directly related to whether vision correction surgery has been performed and may still occur naturally over time.
Will I need follow-up check-ups after surgery?
After SMILE surgery, a follow-up check-up is typically performed within 1–2 weeks to evaluate healing and surgical outcomes. After that, additional visits are optional unless you experience significant changes in vision or discomfort. However, because eye health involves more than just the cornea — such as the retina and optic nerve, which can affect vision — annual comprehensive eye exams are strongly recommended, regardless of whether you have undergone vision correction surgery.
Are there any side effects after surgery?
After SMILE surgery, temporary side effects such as glare, nighttime halos, and dry eye symptoms may occur. In most cases, these resolve naturally within a few weeks and can be managed with artificial tears or prescribed medications. In rare cases, visual recovery may be slower, or a small residual refractive error may remain. If necessary, enhancement procedures can be performed. Serious complications such as corneal inflammation or opacity are extremely rare and are typically treatable with medication when detected early.
When will my vision improve after surgery?
After SMILE surgery, vision may be slightly blurry on the day of the procedure. However, most patients experience clear vision starting the next day. Temporary symptoms such as glare, halos, or dry eye may occur depending on corneal healing and dryness, but these typically improve within 1–2 weeks. Vision generally stabilizes during this period, with final visual outcomes achieved within 1–3 months. Recovery speed and visual outcomes vary depending on individual eye conditions and preoperative vision. Additional treatments such as corneal strengthening or dry eye management treatments may help enhance recovery and surgical results.
What if I blink or move my eyes during surgery?
During all vision correction procedures, a device called a lid speculum is used to gently keep the eye open, preventing blinking. Eye movement is involuntary and cannot be fully controlled by the patient. To ensure accuracy, advanced laser systems are equipped with eye fixation and tracking technology (such as VisuMax fixation and Amaris Red eye-tracking systems), which monitor and compensate for eye movement in real time. In extremely rare cases where fixation is lost, the surgeon will determine whether to safely continue the procedure or convert to an alternative method such as LASEK, depending on the situation.
