Scientists have developed a new method of permanent vision correction. In the near future, everyone will be able to undergo a simple surgical procedure and then stop wearing contact lenses or glasses.
The procedure (referred to as ‘Z Kamra’) involves inserting a special plastic implant in the eye after a small incision is made in the cornea. The implant, which is smaller than a contact lens, is placed around the iris and the pupil, and acts like a pinhole camera, reducing the amount of light that reaches the retina to the beams that produce the clearest images. The beams that are on the outer range of vision (useful in dark light, but not producing clear images) are blocked, and the patient can enjoy perfect vision.
However, according to Dr Larry Benjamin, an eye surgeon, Z Kamra (which costs £2,800 per eye (£4,600 for two)) is not suitable for everyone and people of certain professions (e.g. pilots) will not be able to undergo it.
