Abstract
Description
本願は、2009年2月19日に出願された米国仮特許出願第61/153709号明細書と、2009年2月26日に出願された米国仮特許出願第61/155562号明細書とについての優先権を主張する。
仰臥位における眼の眼球回旋(cyclo-torsional)位置が、上向きの座位における、麻酔されていない眼の対象物への凝視の間に定められるような眼の位置に関連するので、仰臥位における角膜頂の配置及び眼の眼球回旋位置を定めるための技術が本明細書において開示される。一旦、角膜頂の位置が定められると、その後、眼球の虹彩、強膜、又は結膜組織若しくは上強膜組織における解剖学的な目印が、二つ以上の参照点を作り出すべく角膜頂と共に使用されることができ、このため、眼の表面上の特定の経線(meridian)の角(度)の再現可能な位置特定が可能となり、次いで、乱視又は他の非対称な光学収差を矯正すべく眼の内側に眼内レンズを正確な回転方向に定置することが可能となる。
r’=sqrt(r2+r0 2+2rr0cos(θ−θ0))
θ’=arctan([rsin(θ)+r0sin(θ0)]/[rcos(θ)+r0cos(θ0)])
x=rcos(θ)
y=rsin(θ)
r=±sqrt(x2+y2)
θ=arctan(y/x)
