NEW IMPLANT -RAIN DROP CORNEA


SCIENTISTS    have  developed   a  tiny  implant  , no  bigger  than  a  pinhead ,  which sits  inside&n bsp; the cor nea  to  reverse  vision  problems in  aging  eyes .
With  the   age  ,some  people's  ability  to switch    focus  between  near   and  distant  objects  diminishes , a  condition  known  as  presbyopia .It  can   skew  the  perception  of   depth  and  makes  reading  in  poor  light   impossible .
The  new  implant   slightly  increase  the  curvature  of the  cornea,which  allows the eyes  to  focus  again.This  new   technique   ,known   as a' Raindrop   corneal  inlay'  was  developed  by  scientists  at  Revision  Optics  in  California.The  first  operations   have now  been  carried  out  at a  clinic  in  Warwickshire .The  inlay  is  called  Raindrop   because   it  is  in  the shape  of a droplet  and  is  made  of  hydro-gel,  a  substance  which  is  also  used   in  contract   lenses. Hydro gel  is  80 percent  water   which  makes  it  more  compatible  than  other  implants.
