Abstract

본 발명은 치수가 균일하지 않은 지질내 각막 링(‘ICR’)에 관한 것이다. 그것은 전형적으로 링에서 서로 떨어져서 두군데 이상 높아진 영역(54,60)(또는 부가적인 크기의 영역)을 갖는다. 이 링설계는 지질내에 도입 되어 거기에서 적절히 조절했을때 눈에서 적어도 부분적인 난시의 교정을 허용한다.

Description

난시교정용 지질내의 각막 링(ASTIGMATIC CORRECTING INTRASTROMAL CORNEAL RING)
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 눈의 수평단면 개략도이며,
제2도는 각막의 여러층을 나타내는 눈의 전면부의 개략도이며,
제3도는 각막내에 존재하는 본 발명 ACICR을 묘사하며,
제4도는 각막내 ACICR의 측단면도,
제5도는 눈안에 ACICR의 배치를 나타내는 정면도.

  5. 제4항에 있어서, 비교적 더큰 치수의 두영역들은 링에서 약 180°떨어져 간격져 있는 것을 특징으로 하는 링.
  6. 제1항에 있어서, 눈에서 링을 위치시키기 위한 조절수단을 추가로 포함하는 것을 특징으로 하는 링.
  7. 제1항에 있어서, 단면은 비교적 더큰 단면의 두군데이상 영역을 갖는 것을 특징으로 하는 링.
  8. 제2항에 있어서, 비교적 더큰 치수의 두영역들은 링 전체적으로 대칭이 아닌 것을 특징으로 하는 링.
  9. 제1항에 있어서, 분리 링의 단부들은 접합가능한 것을 특징으로 하는 링.
  10. 제1항에 있어서, 한가지 이상의 생리학적으로 허용되는 중합체로 이루어지는 것을 특징으로 하는 링.
  11. 제10항에 있어서, 중합체는 폴리메틸메타크릴레이트로 이루어지는 것을 특징으로 하는 링.
  12. 제10항에 있어서, 팽윤성 중합체를 추가로 포함하는 것을 특징으로 하는 링.
  13. 제12항에 있어서, 팽윤성 중합체는 폴리히드록시 에틸메타크릴레이트와 폴리비닐피롤리돈으로 부터 선택되는 것을 특징으로 하는 링.
