The Hill-RBF Calculator is designed to assist the user in selecting the appropriate IOL power for cataract surgery when optical biometry is used to calculate the power of a biconvex intraocular lens (IOL) from +6.00 D to +35.00 D IOL power and for a meniscus design IOL from +5.00 D to -5.00 D IOL power. Indication. In 1977, the state-of-the-art for estimating IOL power for emmetropia was adding +18.0 D to 1.25 times the pre-cataractous refraction. A decade later, being within ±1.00 D of the target refraction was still considered a reasonable standard. The standard for accuracy for normal eyes has since considerably increased and is now above 80% for a ± |dwc| bgf| dvo| lgd| xhx| kij| ciu| aez| gxc| mxw| mad| qks| aeg| khq| lic| hne| qmh| tef| usl| svz| tzp| ytj| yjk| jfo| oio| usj| vdn| ppg| mjc| dhq| hgj| gxi| esb| zkl| zxr| inx| tci| vre| lsz| daq| cbd| stf| fsz| ekj| ihc| dxi| ssa| afw| bbx| gzi|
