A Prospective, randomized, controlled, post-marketing clinical study to assess clinical performance and safety of EYECRYL Sert intraocular lens (IOL) versus TECNIS EyhanceTM IOL in patients with planned age-related cataract surgery

Presbyopia is one of the most common causes of vision impairment, affecting an estimated 2 billion people, globally . Presbyopia has been associated with negative impacts on quality of life in people aged 40 and above from developing and developed nations alike – because it causes difficulties with reading and with accomplishing near vision tasks.

Non-invasive methods of correcting presbyopia have been used for many years. While bifocal or multifocal progressive addition lenses, monofocal or bifocal contact lenses can provide satisfactory distance and near vision to presbyopes without the potential risks of a surgical procedure, they cannot restore or substitute the true process of accommodation of a younger individual.

Among the surgical options, presbyopia correction can be achieved with excimer or femtosecond laser ablation on cornea (LASIK, PRK, Presbylasik, Supracor, Intracor, etc.), Another recent corneal approach is the insertion of inlays, both artificial and made of corneal tissue in order to change the central curvature of the cornea.

Lens extraction with implantation of multifocal, monofocal (monovision) or accommodative intraocular lenses is another method for correction of presbyopia and has started to become the preferred method for presbyopic correction, particularly in a cataract-aged population. Multifocal IOLs provides good distance and near vision but usually provide not sufficient intermediate vision . Moreover, they might be linked to visually significant light-related experiences that could be highly uncomfortable and necessitate extremely careful patient selection. Therefore, monofocal IOLs continue to be the most commonly used intraocular lenses in cataract surgery. However, there exists a need for an IOL that can provide a favorable compromise between clear distance and intermediate vision, while also addressing issues related to light sensitivity.

The introduction of the newest IOLs with extended depth of focus (EDOF) technology facilitated a relatively favorable visual performance across intermediate, far, and near distances.

This study seeks to compare a new Advanced Monofocal IOL with extended depth of focus vision, the EYECRYL Sert intraocular lens with the TECNIS EyhanceTM IOL.
