There is a difference between mild dry eye and structurally compromised ocular surface disease.
Severe dry eye, particularly aqueous deficiency or autoimmune-related dryness, increases the risk of chronic postoperative neuropathic pain and fluctuating vision.
Refractive surgery reviews consistently emphasise that significant pre-operative dry eye is a contraindication or strong relative contraindication. ¹ ²
Corneal nerve transection during LASIK reduces feedback to the lacrimal gland. In already compromised patients, this can destabilise tear homeostasis for prolonged periods. ³
Red flags include:
- Marked corneal staining
- Schirmer values below accepted thresholds
- Sjögren’s syndrome
- Chronic ocular surface inflammation
- Meibomian gland failure unresponsive to treatment
If optimisation strategies do not restore stability, proceeding would increase risk of persistent discomfort.
At Blue Fin Vision®, long-term comfort outweighs cosmetic goals.
Severe dry eye is not simply a symptom.
It is a signal that the ocular surface may not tolerate elective corneal intervention safely.
