Ocular Surface

Why Dry Eye Treatment Comes Before Surgery

That gritty, burning, watery discomfort is not just an annoyance — an unstable tear film skews measurements and slows healing.

The measurement problem

Biometry for cataract lenses and topography for refractive surgery both assume a stable corneal surface. An unstable tear film makes the cornea’s shape readings wander — the same eye can measure differently hour to hour. Operating on moving measurements is planning with a blurred map.

The healing problem

Every eye surgery involves the ocular surface, and a compromised surface heals more slowly and less comfortably. Dry-eye symptoms that would have been a mild nuisance become a genuine post-operative burden. Treating the surface first is therefore not a delay — it is the first stage of the operation.

The practical programme

Foundations come first: preservative-free lubricants, blink discipline and screen breaks, lid hygiene, and humidity control. Then targeted therapy for the specific deficiency — anti-inflammatory drops for inflamed surfaces, warm compresses and meibomian care for evaporative disease, plugs for aqueous deficiency where appropriate. Most surfaces stabilise within weeks, and the surgical conversation resumes on solid ground.
