EVO/EVO+ Visian Implantable Collamer Lenses for the correction of myopia and myopia with astigmatism

ABSTRACT

Introduction

Intraocular lens implantation in phakic eyes for the correction of refractive error is currently a widespread procedure. The EVO and EVO+ Visian Implantable Collamer Lenses (ICL) are two of the most prevalent lenses implanted. They incorporate a central orifice to avoid the need for iridotomy. The main difference between both ICL is the higher optical diameter zone provided by the EVO+, allowing a better quality of vision at night. This review aims to provide an overview of the current ICL models available for correcting myopia and myopic astigmatism.

Areas Covered

During the last decade, more than 100 scientific papers analyzing the performance of EVO and EVO+ lenses have been published. This review describes the objective visual performance achieved with the implantation of central hole ICL lenses and the subjective perception of the patients implanted with these lenses. In addition, the safety and the potential complications associated with undergoing an EVO and EVO+ ICL implantation have been addressed.

Expert Opinion

Refractive surgeons and candidates to undergo ICL implantation should be aware of the excellent safety and visual outcomes provided by the implantation of central hole ICL lenses. However, future research could address minor issues currently not resolved.

Article highlights

• EVO and EVO+ Visian Implantable Collamer Lenses (ICL) incorporate a central hole to allow aqueous humor circulation avoiding laser iridotomy and reducing the prevalence of related complications.

• The implantation of EVO and EVO+ ICL is a safe, effective, and predictable procedure widely used for the correction of myopia and myopia with astigmatism.

• Dysphotopic phenomena could be perceived after ICL implantation although it is expected to progressively disappear during the medium postoperative period.

• The ocular structures and lens integrity should be monitored in order to guarantee long-term safety on a yearly basis eye examination.
