PATIENT EXPERIENCE
‘The weeks that followed were interesting, I had some frustrations with slight blurriness here and there. I went in to see Mr Hove and he reassured me that it was just to do with dryness and a surface issue. It was reassuring to be able to follow up with him in person and be sure and, as predicted, my eyes are now feeling really solid at the month mark.’
This page is for patients who have had LASIK (laser in situ keratomileusis) and are experiencing dry eye symptoms, fluctuating vision, light sensitivity, grittiness, and want to understand what is happening, how long it lasts, and when to seek review.
Why LASIK Causes Dry Eye
LASIK severs corneal nerves in the flap interface.³ ⁵ These nerves provide the feedback signal that drives the blink reflex and stimulates lacrimal gland secretion.⁴ When disrupted, blink rate falls, tear production decreases, and the tear film becomes unstable. Variable vision, light sensitivity, and grittiness follow.
This is the most common post-LASIK complaint, and the one most commonly misinterpreted.¹ ² The laser correction is fixed and stable from day one. What fluctuates is the tear film sitting above it. Most patients who struggle in these weeks assume the procedure has not worked. It almost never means that.
The Timeline of Post-LASIK Dry Eye
- Day 1 to Week 4: symptoms most prominent. Preservative-free lubricating drops are the primary management, used frequently, not sparingly.
- Week 4 to 3 months: gradual improvement as corneal nerve regeneration occurs. Vision stabilises as the tear film becomes more consistent. This patient’s experience, solid vision at one month, is the expected trajectory.
- 3 to 6 months: corneal sensation typically restored. Dry eye symptoms resolve in the vast majority of patients by six months.⁵
Who This Is Not For
This page is not for patients with significant pre-existing dry eye who were advised LASIK would worsen their condition. For those patients, ICL (implantable Collamer lens), which does not touch the corneal surface, may be considered as an alternative. If symptoms are severe or worsening, seek formal review rather than continuing to self-manage.
Clinical Perspective
At Blue Fin Vision®, Mr Mfazo Hove manages post-LASIK dry eye proactively at every follow-up review. Published data shows 20 to 40% of LASIK patients experience temporary dry eye in the first three months, a figure that is frequently omitted from pre-operative discussions at high-volume providers.¹ ² Every patient at Blue Fin Vision® receives a written post-operative care plan with lubricant drop protocols. The six-week review includes tear film assessment as standard. Where symptoms are persistent, punctal plugs, prescribed lipid-based drops, or omega-3 supplementation are available, managed by Mr Hove directly, not delegated.
Clinical Takeaway
Dry eye after LASIK is common, expected, and typically temporary. The laser correction itself is unaffected, what fluctuates is the tear film. Resolution occurs progressively from weeks four to six months. At Blue Fin Vision®, dry eye is managed proactively with structured follow-up, not left to patients to manage alone.
