노안환자를 위한 백내장 수술, 노안교정을 위한 각막절제술, 노안교정용 콘택트렌즈 및 안경착용과 같은 다양한 조건하에서 정확하게 시력과 상질을 형상화하는 정밀 노안 모형안이 필요하다. 노안에 대해 최근에 발표된 임상 자료들을 이용하여 광학적, 해부학적으로 실안에 근접하며, 노안을 위한 새로운 정밀 모형안을 설계하였다. 연령의 증가에 따라 달라지는 안 매개변수들을 각각 4개의 연령대별로 다르게 적용하였다. 새 모형안에는 알파각, 편심동공, 비구면 GRIN 수정체 및 비구면 망막 면을 적용하였다. 본 연구에서 제시된 모형안들은 노안을 위한 저시력 보정용구, 누진가입도렌즈, 인공수정체 그리고 콘택트렌즈와 같은 시기광학계의 설계는 물론 임상적으로 망막 상의 질을 평가하는데 유용하게 적용될 수 있을 것이다.
Abstract
There is a need for a finite schematic presbyopic eye that models vision and image quality under various conditions such as cataract or refractive surgery, as well as near vision corrections with an ophthalmic lens or contact lens. Using recently measured biometric data of presbyopic eyes, new model eyes were designed that are optically and anatomically close to real eyes. The parameters changing significantly with age were incorporated into models for four different age groups. The new model eyes have alpha angle, decentered pupil, aspheric GRIN lens and aspheric retinal surface. It is likely that the new finite presbyopic model eyes will be useful for designing visual instruments such as low vision aids, PALs, IOL and contact lenses, and for the clinical prediction of the retinal image quality of a presbyopic patient.
