Scharioth Macula Lens for patients with high myopia: a novel approach to achieve spectacle independence (binocular trifocal monovision)

We aimed to test a novel concept based on multiple IOL-implantation, targeting spectacle independence for patients with high and excessive myopia (26.0 mm < axial length; 6.0 D < refractive error). Therefore, we introduced the first results of five patients with high myopia. After clear lens extraction, one eye was targeted to emmetropia, and the other to mild myopia by implanting monofocal capsular bag IOLs with appropriate refractive powers in each case. The emmetropic eye was aimed to result in magnification and improved distance vision, while the mild myopic eye was supposed to ensure good intermediate vision. Thereafter, a Scharioth Macula Lens (SML) was implanted into the emmetropic eye in order to achieve sharp near vision. Visual acuity curves and defocus curves were plotted postoperatively. According to our results, this new concept seems to be an efficient approach of achieving appropriate uncorrected vision at all distances, by creating binocular trifocal monovision.
