In 2004, HOTA was amended to include the recovering of the corneas, heart
and liver in both accidental and non-accidental deaths. Besides this form of organ donation, regulations were made for living donor organ transplantations (i.e. the removal of organs from a living donor for transplantation into a patient).This raised the average number of patients benefiting from organ donation to 46 per year.

To further increase organs available for transplantation, from 1 November 2009, all Singapore Citizens and Permanent Residents 21 years old and above, who are not mentally disordered, are included under HOTA unless they have opted out.

Those who are under HOTA will not only have the chance to help others, but will also have higher priority on the waiting lists should they need an organ transplant. This will be critical when the need arises.
