Intraocular lens power formulas.
We have developed a FORTRAN digital computer program to evaluate intraocular lens power for any thin lens and combination of corneal curvature and axial length. Partial derivatives of the power with respect to cornea power, axial length, and lens position allow estimation of error in power of the lens. These derivatives are computed along with power of the lens for six far points which may be changed with the program running. The program is written for remote access so that an ordinary telephone and portable terminal provide the ability to compute lens power.
