How safe is the implantation of a 1stQ AddOn Sulcus IOL?

Sulcus-fixated 1stQ AddOn intraocular lenses offer the option of correcting refractive errors or extending the range of vision without exchanging the primary capsular bag lens. This article summarises the published evidence on safety, stability, intraocular pressure (IOP), pigment dispersion, interlenticular opacification and reversibility.

What does the dominant eye reveal? Initial observations on ocular dominance using RALV^®

Understanding Subjective IOL Perception Better – Initial Insights with RALV^® from the Data Collection at DOC 2025

The question of the optimal distribution of near additions in the MIOL setting is as old as the multifocal lens itself. It becomes particularly interesting when considering the role of eye dominance — both motor and sensory.

As part of this year’s DOC Congress, we investigated this question through a data collection study.
