Prosthetic micro-thin lens for eye cataracts
Numéro d’image : 11853991
| Prosthetic eye lens. Dwarfed by an American dime coin,this micro-thin lens (at centre,blue) is the first diffractive eye lens to be designed that corrects for colour distortion. It is 5-10 microns thick,4 millimetres in diameter,consisting of a lightweight plastic polyimide. Conventional lens implants rely on thickness for their power,and have a tendency to split colour. The micro-thin lens solves these drawbacks. Grooves etched on its surface focus colours on the same spot within the eye; while its size and flexibility would make it simpler to implant. This ongoing research may have widespread application in cataract surgery | |
