Claims (2)
- 상호 대응되어 결합되는 암/숫형 프런트 및 베이스 커브 몰드에 콘택트렌즈 원료인 폴리머를 투입하고 소정시간동안 열과 빛을 이용하여 중합시켜 콘택트렌즈를 제조하며 제조된 콘택트렌즈를 취출하는 콘택트렌즈 제조방법에 있어서,상기 암형 프런트커브 몰드로부터 숫형 베이스커브 몰드를 분리시키는 공정과,상기 암형 프런트커브 몰드 내부로 기준척을 삽입하여 상기 암형 프런트커브 몰드내에 압착/성형된 콘택트 렌즈를 용착하여 분리하는 공정으로 상기 콘택트렌즈를 취출한 다음,상기 기준척에 용착되어 분리된 콘택트 렌즈를 콘택트 렌즈 가공프로그램에 따라 다양한 돗수의 렌즈를 가공하는 공정으로 이루어지는 것을 특징으로 하는 콘택트 렌즈 제조방법.
- 단차를 두고 그 일측 끝단부가 소정 곡률로 하여 돌출된 볼록형상면으로 이루어진 숫형 베이스커버 몰드와, 상기 숫형 베이스커버 몰드와 대응되게 결합됨에 따라 그 내부에 콘택트 렌즈 형성층이 구비된 암형 프런트커브 몰드로 이루어지는 것을 특징으로 하는 콘택트 렌즈 제조용 주형 몰드.
