Simulation of eye disease – Glaucoma

common vision and eyesight problems with engineered solutions

  • cataracts – clouding that develops in the crystalline lens of the eye or in its envelope, varying in degree from slight to complete opacity and obstructing the passage of light.
  • near-sight – laser treatment, contact lenses, glasses
  • glaucoma
  • macular degeneration
  • detached retina

Cataracts

  • Cataract surgery – the removal of the lens of the eye (also called “crystalline”) that has developed an opacification (loss of transparency). Following surgical removal of the natural lens, an artificial intraocular lens implant is inserted (eye surgeons say that the lens is “implanted”).
  • Phacoemulsification (Phaco) – an ultrasonic handpiece with a titanium or steel tip vibrates at ultrasonic frequency (40,000 Hz) and the lens material is emulsified.
  • foldable intraocular lens (IOL), made of silicone or acrylic material of appropriate power

Electronic glasses

  • Electronic Glasses Allow Legally Blind Woman To See Her Baby For First Time – The electronic glasses, which are called eSight, combine multiple different components that can be adjusted by the user to enhance the quality of an image reaching the eye. The headset, which is mounted on lens frames, houses a high-definition camera which feeds real-time video footage onto organic light-emitting diode screens placed directly in front of the user’s eyes. A separate handheld device allows the user to adjust and magnify the image so that they can gain the best possible picture of the world around them.
