Anterior segment surgery has experienced a huge development in the last 25 years. Presently, in spite of this accelerated development, new technologies have emerged that have impacted considerably the surgery of the crystalline lens, the cornea and its pathologies. Corneal blindness, corneal debilitating diseases (corneal ectatic disease), corneal opacities, post infectious or traumatic problems and complication of cataract surgery has increased the rate of performance of corneal surgery, with corneal blindness still being a worldwide problem. Concerning the crystalline lens, cataract surgery is the most widely performed surgical procedure in the human being, and every step forward in this surgery affects millions of people around the world every year. Corneal surgery has been opened to a new stage of development thanks to the introduction of femtosecond laser technology, corneal crosslinking procedures, better knowledge of corneal biomechanics, improvements in corneal transplantation, development of corneal regenerating techniques, new antiinflammatory and immunological medication and a better knowledge about the ocular surface biological behaviour. Crystalline lens and cataract surgery have experienced a major recent impact with the introduction of femtosecond lasers for cataract surgery, and the so‐called premium IOLs. Jointly, they represent a large step forward in the outcomes that are expected for cataract surgery, in which not only vision research is expected but also the spectacle independent condition for far and for near. Different models of accommodative lenses, multifocal lenses and other technologies have approached this refractive purpose. In this presentation the actual trends based on evidence based knowledge about the immediate evolution of corneal and crystalline lens surgery, the recent developments in the knowledge of the corneal diopter in normal and diseased conditions and the implementation that cataract surgery and IOL technology is undergoing today will be explained. The concept of eye modelling with modern customization of all these procedures through a global modern eye based on recent knowledge will be also outlined.
