Abstract

원환체표면을 비구상화하여 물품 명세서내에 있는 물품 유지단위에 필요한 원통형 축위치의 수를 감소시키는 비구상 원환체렌즈를 기재하였다. 본 발명은 안렌즈, 특히 비원시성 또는 원시성 난시환자가 착용하도록 설계된 소프트하이드로겔 콘택트렌즈와 같은 콘택트렌즈에 관한 것이다. 비상구원환체 렌즈의 전면과 후면중의 하나는 적어도 환자의 기본 원거리처방전(Rx)에 상응하는 구상표면을 구성한다. 전면과 후면중의 다른 하나는 비구상원환체 곡면을 구성하며, 원환체표면은 비구상반경으로 이루어져 있어서 비구상곡면은 촛점의 깊이 (depth-of-focus)를 증가시킴으로써 원환체곡면의 어긋한 축상배열을 감소시킨다. 비구상원환체곡면이 렌즈의 후면위에 놓이는 경우, 렌즈의 전면위의 구상곡면이 환자의 기본원거리처방전(Rx)에 상응하는 단일구상 곡면을 포함할 수 있다. 비구상원환체 곡면이 렌즈의 전면위에 놓이는 경우, 렌즈의 후면위의 구상곡면이 다촛점 동심 환형환 구상 표면을 포함할 수 있다.

Description

비구상 원환체 렌즈
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 축위치가 180°인 비구상원환체 표면으로 이루어진 후면과 환자의 기본구상 처방전(Rx)에 상응하는 구상전면을 갖는, 본 발명에 따르는 비구상 원환체렌즈의 제1양태의 후면 평면도를 도시한 것이고, 제2도는 원환체표면의 잠재적인 비구상화효과, 원환체표면의 주축과 종축에서의 구상단면을 갖는 원환체표면(점선으로 표시) 및 또한 원환체표면의 주축과 종축에서의 비구상단면을 갖는 원환체표면(실선으로 표시)을 도시한 것이며, 제3도는 축위치가 90°인 비구상 원환체표면으로 이루어진 난시교정용전면과 환자의 기본구상 원거리 및 근거리 교정처방전(Rx)에 상응하는 다촛점동심환형환을 포함하는 원시교정용 후면을 갖는, 본 발명에 따르는 원시성 난시환자용 비구상 원환체렌즈의 제2양태의 전면평면도를 도시한 것이다.
