Abstract: This review describes the principles and practice involved in the calculation of intraocular lens(IOL)refractive power. The theories behind formulas for calculating IOL power are described, using regression and optical methods. The review emphasizes the importance of establishing a precise estimation of corneal power as well as accurate techniques for the measurement of axial length and for predicting postoperative anterior chamber depth. The review concludes that current improvements in diagnostic and surgical technology, combined with the latest IOL refractive power formulas, make the calculation and selection of appropriate IOL power among the most effective tools in refractive surgery today.

Key words: Corneal curvature, Axial axis, Effective crystal position, Intraocular lens refractive power
