Dry eye disease is common. Mild symptoms do not automatically rule out laser eye surgery, but severity matters.
Laser procedures temporarily disrupt corneal nerves responsible for tear production and blink reflex. In healthy eyes this usually causes short-term dryness. In patients with pre-existing dry eye, however, symptoms can become prolonged or even chronic. ¹
Prospective studies have shown that worse pre-operative tear function and higher symptom scores significantly increase the risk of persistent post-LASIK dry eye. ² Reviews of refractive surgery complications consistently identify moderate-to-severe dry eye as a major risk factor. ³
Warning signs include:
- Low tear break-up time
- Reduced Schirmer testing
- Significant corneal staining
- Autoimmune disease affecting lacrimal glands
- Severe contact lens intolerance from dryness
At Blue Fin Vision®, the question is not simply “Do you have dry eyes?” but “How stable and resilient is your ocular surface?”
If dryness is mild and optimisable, treatment and reassessment may make surgery reasonable. If dryness remains significant despite appropriate management, corneal laser may worsen long-term comfort.
Visual clarity without comfort is not success.
When the ocular surface is fragile, saying “not suitable” protects quality of life, not just chart vision.
