Some Postoperative Symptoms You May Encounter Following SILK Refractive Surgery

18/02/2025

 

While SILK is a gentle and advanced method for correcting myopia and astigmatism, like any surgical procedure, it may come with some temporary side effects. These are usually mild and manageable, but being aware of them can help you feel more prepared and support a smoother recovery.

Here are some common postoperative symptoms reported by patients, along with medical insights from Japan International Eye Hospital:

1. Temporary Difficulty with Near Vision

After surgery, your eyes need time to adjust to the new refractive state. If you were previously nearsighted, you may notice some difficulty focusing on close objects during the early recovery period. This is a normal part of the adaptation process and typically improves over several weeks to a few months, depending on each person’s natural adjustment.

2. Mild Haze or Blurry Vision

Some patients experience mild visual haze or a slightly “milky” appearance in their vision right after the procedure. This is caused by the temporary separation of corneal layers during surgery, which naturally reattach over time as fluid between them is reabsorbed.

Thanks to SILK’s ultra-precise laser pulses and unique biconvex lenticule design, healing tends to be quicker and clearer than with other procedures. Most cases of haze improve significantly within a few days to a few months.

3. Dry Eye 

Although SILK refractive surgery is designed to preserve corneal nerves, especially at the periphery, some patients may still experience mild dryness in the eyes during the early postoperative period. The application of artificial tears is recommended to maintain ocular surface moisture.

This symptom is generally temporary and can vary in intensity based on individual physiology and environmental conditions. Proper use of lubricating eye drops usually provides sufficient relief.

4. Sensitivity to Light (Photophobia)

Increased sensitivity to light or seeing halos around bright lights is a common temporary effect, especially in dim conditions when the pupils are more dilated. This occurs due to the difference in how light passes through central and peripheral parts of the cornea.

SILK’s precision laser technology helps minimize these optical side effects, and most patients find that the sensitivity fades as their eyes adjust over the first few months.

5. Eyelid Discomfort or Difficulty Opening the Eyes

Some patients may feel a slight heaviness in the eyelids or have difficulty opening their eyes shortly after surgery. This is usually due to the eyelid speculum used during the procedure and typically disappears within a day or two.

6. Subconjunctival Hemorrhage (Eye Redness)

A red patch on the white part of the eye can sometimes appear after surgery. This is called a subconjunctival hemorrhage and results from minor bleeding under the conjunctiva. It may also be triggered by alcohol, tobacco, or physical strain.

Though it may look alarming, it’s harmless and doesn’t affect vision. It usually clears up on its own within two to four weeks. To prevent it, patients should avoid alcohol, tobacco, and stimulants for at least 3–5 days after surgery.

7. Risk of Infection

Infection after SILK surgery is very rare, but like with any procedure, it’s important to follow your postoperative care instructions carefully. This includes using your prescribed antibiotic and anti-inflammatory eye drops as directed by your ophthalmologist.

Conclusion

SILK refractive surgery effectively corrects corneal curvature and restores vision. As the eyes recover, it is natural to encounter temporary side effects, most of which resolve as healing progresses. Patients are encouraged not to be alarmed and to remain in close communication with their care team throughout the recovery period.
