This site provides general eye-health education. It cannot replace individual assessment by a registered doctor, and does not offer personal diagnosis, prescriptions, bookings, sales or referrals.

Allergic conjunctivitis includes seasonal forms and heavier types (e.g. vernal / atopic keratoconjunctivitis).
Care principles focus on trigger avoidance and doctor-guided drug classes — not brand pitches.
Do not self-extend steroid eye drops; long use raises IOP and cataract risk and needs review.
Off-label eyelid tacrolimus is covered on related pages; red-flag paths are on the steroid-sparing page.
Allergic conjunctivitis includes seasonal/perennial disease, vernal keratoconjunctivitis (VKC) and atopic keratoconjunctivitis (AKC). This page outlines drug classes and known risks a doctor may discuss — it does not recommend buying any product. Prescription medicines need a registered doctor; off-label use needs informed consent.
Topical corticosteroid drops / ointments
Prescription only. Literature reports acute inflammation may ease within one to two days. Hong Kong doctors choose strength by severity and monitor pressure and the lens. Do not self-extend or buy “strong” leftover drops.
Raised IOP (steroid glaucoma); some people are steroid responders
Posterior subcapsular cataract
Higher risk of bacterial, herpes simplex and fungal infection
Delayed corneal wound healing
Do not lengthen steroid drops yourself. Long-term use raises pressure and cataract risk — follow-up is required.
Ciclosporin eye drops
Prescription immunomodulator; onset often takes weeks. Hong Kong registration examples, EU public information and VKC/AKC label distinctions are on the steroid-sparing medicines page.
Tacrolimus ointment (eyelids)
Mainly dermatology-registered in Hong Kong; eyelid use is usually off-label — not as eye drops. Warnings and red flags: see the steroid-sparing hub and the eyelid-tacrolimus short page.
This is general medical information, not a diagnosis, and cannot replace an in-person consultation with a registered ophthalmologist, refraction, or a dilated fundus exam. It is not advice to use any medicine or undergo any procedure. Medicines (including off-label use), laser or surgery must be decided by a registered doctor after examination, according to indications and Hong Kong registration. Figures from the literature are published averages, not any clinic’s results. This site does not book, prescribe or refer. Do not change treatment on your own.
