Abstract Details

Purpose:

To test the efficacy of a novel concept based on multiple IOL-implantation, aiming spectacle independence for patients with high to excessive myopia.

Setting:

Aurelios Augenzentrum Recklinghausen, Recklinghausen, Germany

Methods:

Five patients with high myopia were included in our proof-of-concept study. 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. 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 ciliary sulcus of the emmetropic eye in order to achieve sharp near vision. Visual acuity curves and defocus curves were plotted for all cases postoperatively.

Results:

Far vision improved significantly after surgery, as best corrected distance vision (BCDVA) improved from the preoperative mean value of 0.51 ± 0.24 (SE = -14.4 ± 4.72 D) to 0.68 ± 0.16, with requiring only an average correction of SE = 0.08 ± 0.65 D. Near vision was assessed by the Radner reading chart: an average improvement of 4 lines (range: 2-8 lines) could be achieved. Final refractive outcome after all surgeries resulted in a SE = -0.13 ± 1.25, while IOP remained unchanged during the whole surgical and follow-up period. No surgery related complication occurred.

Conclusions:

The new concept using the SML in patients with high to excessive myopia (AL <26.0 mm; refractive error <8.0D) seems to be an efficient approach in achieving appropriate vision at all distances, by creating a binocular trifocal monovision. Patients welcomed the visual outcome with high satisfaction, however our initial favourable results with this novel management of high myopia requires further evaluation.
