The analytic formula of phakic intraocular lenses(PIOLs)power to correct myopia,hyperopia and eye's senior aberration is presented based on optical system model of human eyes,which improves the calculation accuracy of PIOL power compared with the experience formula.When the implanted PIOLs have the same power and central thickness but different optical structures,the imaging quality of eyes are analyzed in detail by using the ZEMAX optical design software.The results show the PIOLs with convex-concave structure are superior to the others on improving the imaging quality of eyes.
