  1. Cataract Surgery

  2. Practical Exercise What might it be like to live with cataracts?

  3. Cataract Surgery The cataract lens which has caused the eye to become cloudy is replaced by a plastic lens called an Intraocular Lens, or IOL.

  4. What’s an Intraocular Lens? The Intraocular Lens (IOL) is a small plastic lens with plastic side struts to hold the lens in place when it’s implanted into the eye. Intraocular lenses are vital for restoring sight to people with cataracts.

  5. How is the surgery performed? • Before the surgery, the pupil of the eye is dilated with eye drops to expose the cloudy lens. • The eye is numbed and unable to move. • The patient remains awake. • The eye is clamped open. • A cut is made just below the clear covering of the iris and pupil. • This cut will be self healing and will not require stitching.

  6. The cataract lens is removed. • An intraocular lens (IOL) will replace it and restore the eye’s focussing power. • This lens will stay in the patient’s eye for their lifetime. • The eye is bandaged with an eye patch to prevent infection or injury. • The bandage will be removed within 24 hours and sight will be restored.

  7. Patient Cataract Surgery Watch this patient story on cataract surgery.

  8. Viewing sheet Answer these questions once you have watched the patient story What caused Nawere and Timwias’ blindness? How has their blindness impacted their lives? How has their blindness impacted their mental and emotional health? How did they feel when their sight was restored? How will their lives be different now?

  9. Fred Hollows & Cataract Surgery The Fred Hollows Foundation NZ uses Intraocular Lenses in their sight-saving cataract surgeries. But if these lenses were made in New Zealand they would cost hundreds of dollars to manufacture. As you have learned their founder Fred Hollows knew this and did something about it!

  10. Fred Hollows & Cataract Surgery In the last years of his life, Fred Hollows worked hard to open factories in two developing countries. One year after he passed away, two laboratories were opened in Eritrea and Nepal. Fred holding an IOL

  11. Fred Hollows & Cataract Surgery To date, the laboratories have manufactured over four million lenses that are used locally and exported to more than 40 countries. In some countries like the Pacific Islands and Papua New Guinea, The Foundation can restore sight for as little as $25.

  12. What’s the difference between a cataract procedure in a developing country and New Zealand? In these countries people may be living on only a few dollars a day. If you look at the $25 it costs for an operation as a percentage of their yearly income it can be similar to the amount it costs in New Zealand. To compare – the surgery costs approximately $3,500 in New Zealand, where the average yearly income is around $50,000.
