Question 1

What is the difference between dry eye treatment and artificial tears from a pharmacy?

Accepted Answer

Over-the-counter artificial tears provide temporary symptomatic relief but do not treat the underlying cause of dry eye disease. Effective dry eye treatment begins with identifying the specific cause — whether MGD, blepharitis, aqueous deficiency, or digital eye strain — and delivering a targeted treatment plan addressing that cause directly. For many patients, personalised advanced eye treatment including meibomian gland therapy, punctal plugs, or prescription cyclosporine drops provides lasting relief that artificial tears alone cannot achieve.

Question 2

Can keratoconus be treated without a corneal transplant?

Accepted Answer

Yes — in many cases. Corneal cross-linking (C3R), performed at the right stage of keratoconus, halts disease progression and preserves the cornea sufficiently for ongoing visual rehabilitation with contact lenses or glasses. Our eye specialist doctors counsel every keratoconus patient on the importance of early detection and timely cross-linking, precisely to avoid the need for corneal transplant. However, for advanced keratoconus with significant scarring or intolerance to contact lenses, DALK or PKP corneal transplant may be necessary.

Question 3

How long does recovery take after a corneal transplant?

Accepted Answer

Recovery after corneal transplant depends on the type of procedure. DSEK patients typically achieve useful vision within 1–3 months. DALK and PKP patients may take 12–18 months for full visual stabilisation, as the corneal sutures are removed gradually and refraction settles over time. Our eye care hospital provides structured comprehensive eye care follow-up throughout the entire recovery period.

Question 4

Is it safe to have LASIK eye surgery if I have dry eye disease?

Accepted Answer

Significant dry eye disease is a relative contraindication to LASIK eye surgery, as the procedure disrupts corneal nerves and can worsen existing dry eye symptoms. Our eye specialist doctors assess tear film quality and ocular surface health as part of every comprehensive pre-operative eye checkup for LASIK candidates. Patients with dry eye are referred for dry eye treatment before refractive surgery is considered, and may be better suited to SILK or ICL, which cause less disruption to corneal innervation.

Question 5

What causes a pterygium and can it come back after surgery?

Accepted Answer

Pterygia are primarily caused by chronic UV exposure and are more common in people who spend significant time outdoors without UV-protective eyewear. Recurrence after surgery is a genuine risk, which is why MediVision performs pterygium excision with conjunctival autograft and tissue glue — the technique associated with the lowest recurrence rates. Post-operative comprehensive eye care and UV protection guidance are provided to all pterygium surgery patients.

Question 6

Can children develop keratoconus or dry eye disease?

Accepted Answer

Yes. Keratoconus can begin as early as age 10–12, and early detection through a comprehensive eye checkup is critical, as cross-linking is most effective before significant corneal thinning occurs. Children with a habit of vigorous eye rubbing, often associated with allergic eye disease, are at elevated risk and should be assessed by our pediatric eye care team. Dry eye disease is also increasingly seen in children and adolescents due to digital device use.

Question 7

How do I know if my eye discomfort is dry eye disease or something else?

Accepted Answer

Eye discomfort has many causes, including dry eye, allergic conjunctivitis, blepharitis, corneal ulcer, and elevated intraocular pressure (glaucoma). Self-diagnosis is unreliable. A comprehensive eye checkup is the only way to accurately identify the cause and initiate the appropriate advanced eye treatment. Our cornea eye specialist doctors assess the complete ocular surface and anterior segment at every consultation, ensuring no co-existing condition is missed.
