EWAP SEPTEMBER 2020 17 FEATURE that delivers light energy to soften blockages of the meibomian glands. Results are maximized when combined with microblepharoexfoliation, she said. Dry eye and premium lenses Dr. Trattler said that premium lenses, especially presbyopia- correcting lenses, can be sensitive to residual astigmatism. Physicians have to be sure that they are getting accurate measurements so that the optimal lens power is selected, he said. This typically requires aggressive treatment of MGD and dry eye first to obtain good measurements. Dr. Trattler also mentioned the Light Adjustable Lens (RxSight), where the measurements and in-lens refractive treatments are done 3–4 weeks after surgery. For patients that receive these lenses, it’s important to pretreat and optimize their ocular surface and continue this treatment until the lens power is locked in. “Especially for patients who are paying out of pocket for a premium lens, we need to nail that refractive outcome, otherwise we’re going to have an unhappy patient,” Dr. Matossian said. Their expectation is beyond perfect because they’re paying thousands of dollars, she added, so tuning up the surface to get more reliable information is important, especially in a subset of patients seeking less dependence on spectacles. If they have very severe dry eye Visually significant corneal staining is common prior to cataract surgery, but patients are often asymptomatic.

This big data is analyzed by pattern recognition based on artificial intelligence leading to highly accurate IOL predictions and providing confi- dence thanks to a unique reliability check. Hill-RBF 2.0 The new version of RBF is based on a bigger dataset consis- ting over 3x the amount of data compared to the previous version. This leads to an impressive outcome of 94.8% within ±0.5 D in all eyes*. In addition the Hill-RBF was complemen- ted with the well-established Abulafia-Koch algorithm for torical applications. * n = 288 / Clinical Study: Sperical Equivalent Results, Steven V.
