Sight-restoring surgery
Cataract is the largest single cause of avoidable blindness in the world, and the operation that reverses it takes under half an hour. Funding it is among the highest-yield interventions available anywhere in medicine.
Humanitarian Work
The Case
There are few interventions left in medicine with the arithmetic of cataract surgery. An operation lasting under half an hour, costing a fraction of what it does in Britain, restores a person from functional blindness to independence — and with it their ability to work, to farm, to care for a family, to leave the house unaccompanied.
In much of the world that operation is simply unavailable. Not because it is difficult, but because there is no surgeon within reach, no microscope in the district hospital, and no realistic way to pay for either. The result is a wholly preventable blindness measured in tens of millions of people.
Mr Mohyudin has performed more than 5,000+ of these operations in West Yorkshire. Advising a charity that funds the same operation where it cannot otherwise happen is, he says, the least complicated decision of his professional life.

The Organisation
Funding sight-restoring eye surgery, cancer treatment and emergency disaster relief for poor and disaster-affected families in Pakistan, Indonesia and Malaysia.
Cataract is the largest single cause of avoidable blindness in the world, and the operation that reverses it takes under half an hour. Funding it is among the highest-yield interventions available anywhere in medicine.
The charity works through clinicians licensed in the country concerned — PMDC-registered in Pakistan, KKI in Indonesia, MMC in Malaysia — rather than running clinics of its own. A visiting surgeon who operates and leaves has helped for a fortnight; a funded local unit helps indefinitely.
A no-cash policy: funds are paid directly to accredited partner hospitals rather than handed over in the field. It is an unglamorous governance decision and, in his view, the single most important one on the list.
The same infrastructure funds cancer treatment — breast cancer as the lead programme, expanding into childhood cancers — and emergency disaster relief: food, water, shelter and winter aid for displaced families.

Who Runs It
World Aid Network was founded by Kaiser Khan, a philanthropist and cultural producer, and an External Collaborator on four Disasters Emergency Committee appeals for Christian Aid. He remains founder & trustee, holding personal legal responsibility for grant management, treasury oversight and donor reporting.
Mr Mohyudin's role is narrower and entirely clinical: he advises on the eye programme — which operations are worth funding, what a partner unit needs to deliver them safely, and how to judge whether the money bought what it was supposed to buy. A charity funding sight-restoring surgery ought to have a surgeon in the room when those decisions are made.
It is the least complicated part of my professional life, and the part that most clearly justifies the rest of it.
Working Together
Mr Mohyudin considers a limited number of advisory and mission invitations each year, prioritising programmes with an established local partner and a commitment to strengthening the resident team rather than replacing it.
Charities, NGOs and hospital units seeking a volunteer consultant ophthalmic surgeon or a clinical advisor are welcome to write. Please include the region, the proposed dates, the theatre facilities available and the local partner organisation.

Consultations, treatment information, pricing and referrals are handled entirely through the practice site, with clinics at Spire Elland Hospital and Newmedica in Bradford and Huddersfield.
