Despite benefits, multifocal IOLs can cause fixed focal shift, increased photic phenomena, and limited suitability in eyes with existing corneal aberrations. Monovision offers an alternative but achieves fixed focal points.

Mehta2,3,4*  \nAbstract:  \nIncreasingly, 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.  \nKeywords:  \nAberrated cornea, astigmatism, cataract, centration, extended depth of focus intraocular lens, IC‑8 intraocular lens, intraocular lens, presbyopia, small aperture intraocular lens  \nIntroduction  \nToday, cataract remains the leading cause  \nof blindness worldwide, accounting for 35% of blindness cases worldwide in 2015.[1] While the incidence of cataracts causing severe visual impairment has seen a decline in the past few decades, with the prevalence of cataract blindness decreasing by 11.4%, and moderate-to-severe visual impairment decreasing by 20.2% from 1990 to 2010, rates of cataract surgery have conversely been increasing, with 8 million such surgeries being performed in the United States and European Union yearly. [2-5] This can be attributed to the significant increases in visual function and quality of life that patients receive from cataract surgery.[6-9]  \nAlongside these trends, there has been a shift in patient expectations, with greater  \nThis is an open access article distributed under the terms of the Creative Commons Attribution-NonCommercialNoDerivatives 4.0 License (CC BY-NC-ND), where it is permissible to download and share the work provided it is properly cited.
