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
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.
Claims (13)
- 각막을 실질적으로 에워싸도록 제작되고 링이 지질내로 도입되기 위해 적합한 단면을 가지며 링의 단면이 적어도 한군데 비교적 더 큰 치수의 영역을 갖는 분리 중합체 링.

- 제4항에 있어서, 비교적 더큰 치수의 두영역들은 링에서 약 180°떨어져 간격져 있는 것을 특징으로 하는 링.
- 제1항에 있어서, 눈에서 링을 위치시키기 위한 조절수단을 추가로 포함하는 것을 특징으로 하는 링.
- 제1항에 있어서, 단면은 비교적 더큰 단면의 두군데이상 영역을 갖는 것을 특징으로 하는 링.
- 제2항에 있어서, 비교적 더큰 치수의 두영역들은 링 전체적으로 대칭이 아닌 것을 특징으로 하는 링.
- 제1항에 있어서, 분리 링의 단부들은 접합가능한 것을 특징으로 하는 링.
- 제1항에 있어서, 한가지 이상의 생리학적으로 허용되는 중합체로 이루어지는 것을 특징으로 하는 링.
- 제10항에 있어서, 중합체는 폴리메틸메타크릴레이트로 이루어지는 것을 특징으로 하는 링.
- 제10항에 있어서, 팽윤성 중합체를 추가로 포함하는 것을 특징으로 하는 링.
- 제12항에 있어서, 팽윤성 중합체는 폴리히드록시 에틸메타크릴레이트와 폴리비닐피롤리돈으로 부터 선택되는 것을 특징으로 하는 링.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
