Small-aperture optics are a dynamic, physiologic solution to the problem of presbyopia. They are effective throughout the range of accommodation loss and in pseudophakia. The small-aperture corneal inlay has proven to be a safe and effective solution for presbyopes with healthy lenses. The new category of small-aperture IOLs is likely to continue to expand as we learn more about how these IOLs can not only extend the depth of focus and reduce HOAs from peripheral light rays, but (in the case of the IC-8) also correct refractive error and provide tolerance to residual error. Additionally, small-aperture lenses provide new opportunities for the therapeutic treatment of eyes with irregular astigmatism or other abnormalities.
