Abstract

각막교정의 최소복귀를 일으키는 방식으로 각막을 국소적으로 가열하고 재형태화시키는 열-각막형성 시스템 및 방법. 본 시스템은 전원(14)에 연결된 프로브(12)를 포함하며, 전원(14)은 상피로부터 각막지질에 이르기까지의 각막내에 열프로파일을 만드는 지정된 전력, 주파수 및 지속시간을 제공할 수 있다. 프로브의 전기적 리턴은 눈꺼풀을 열린상태로 유지케하는 개안기(202)이다. 프로브(12)는 각막과 접촉하도록 놓여지고 에너지가 전원(14)으로부터 눈으로 전달되고 개안기(202)를 통하여 전원으로 되돌아간다. 전원으로부터의 에너지는 프로브팁(240)에 집중되며, 이것이 각막을 국소적으로 가열하고 변형시켜 후속적으로 각막 조직의 수축을 야기한다. 변성된 부위의 패턴이 각막 둘레에 만들어져서 눈의 시력을 교정할 수 있다.
