Patients (especially elderlies) are now encouraged by hospitals to fund their own cataract surgeries at 3-4 times the usual amount to skip the queu.
It is thought that the reason is because NHS (a health insurance company, presumably) has a really long wait list and strict eligibility criterias for patients.
However, NHS also offers free fertility treatments that cost around £34,000 (in contrast to £800 cataract surgery) for patients undergoing sex change treatments.
Charity organisations are worried that old people become increasingly blind and lonely as they are being denied treatment.

Nah, NHS is roughly UK's social security.
