Dynamic Ladas Super Surface helps optimize and refine IOL calculations

Historically, we have been advised to optimize specific IOL formulae for our patients in order to better predict the postoperative refraction and to deliver better visual outcomes. This means that we need to analyze our patient data and then make adjustments so that future IOL calculations are more accurate.The idea is that there are differences in calibration of the devices used in biometry and even differences in surgical techniques that can influence the IOL power calculation and thus the postoperative refractive result. This makes sense because if one keratometer reads 0.5 D different than another, there may be about a 0.5 D difference in IOL power if all other factors are equal. Surgical technique typically refers to steps that affect the effective lens position such as the overlap of the capsulorrhexis over the optic edge in order to secure it. A large, non-overlapping capsulorrhexis may allow the IOL optic to come forward, thereby resulting in a more myopic outcome.
