The article emphasizes the need to deliver a consistent and predictable result with lens calculations to achieve the goal of refractive cataract surgery. Biometry issues are key factors influencing lens calculation accuracy. Options for indirectly determining the effective lens position are the Hoffer Q, the Holladay 1 and the SRK/T two-variable theoretical formulae. There is a new seven-variable formula that takes into consideration the standard axial length and keratometry measurements.

    The article examines the effect of femtosecond laser-assisted capsulotomy on effective lens position (ELP). It was found that the ability of the laser to create a perfectly centered, sized, and circular capsulotomy reduces variability in ELP. Predictability in ELP increases with the use of the...
