Abstract
Increasingly, patients desire spectacle independence postcataract surgery, for which multifocal intraocular lens (IOL) implantation is widely performed. However, multifocal IOLs have certain drawbacks: fixed focal change, increased photic phenomena, and unsuitability for use in aberrated eyes. Monovision is an option, but can only achieve fixed focal points as well. An alternative IOL that bridges the gap between providing an extended depth of focus (DOF) and decreasing induced aberrations is the IC-8 Apthera IOL, which utilizes small aperture technology to provide a continuous DOF with good near, intermediate and distance vision in eyes with up to 1.50D of preoperative astigmatism. Importantly, the IC-8 IOL has shown potential for use in aberrated eyes, demonstrating increased visual acuity at all distances, good contrast sensitivity, minimal photic phenomena, and high levels of spectacle independence in patients with corneal irregularities and higher order aberrations, especially postrefractive surgery. The IC-8 IOL has also been able to achieve good centration and positional stability, which is key for good visual outcomes and spectacle independence after surgery. This paper aims to bring together relevant literature to review the outcomes of IC-8 IOL.
