Fun facts about the eye

  • One donated eye can be used to save seven people’s sight.
  • The gift of eye tissue donation is a powerful act that can restore vision and transform lives.
    • The sclera is divided into six sections and used to support glaucoma patients when they have microinvasive glaucoma surgery (MIGS). During this type of surgery, a MIGS device is implanted to help with fluid drainage of the eye. Lions Eye Bank provides ophthalmologists with a one-sixth section of sclera (from donated eye tissue) to provide a ‘band-aid’ over the device.
    • The rear portion of the eye is unsuitable for transplant, however, no part of a donated eye tissue goes to waste. With permission, this portion of the eye can be used for eye disease research.
