[A new toric diffractive multifocal lens for refractive surgery].

BACKGROUND

Up to now only a combination of lens and corneal surgery in the sense of bioptics could be used in refractive surgery for correcting high myopia, hyperopia or presbyopia in combination with astigmatisms. Since the summer of 2007 the first model of a toric diffractive bifocal intraocular lens is available for correcting combined refractive errors. The first results on 10 eyes from 6 patients are presented in this article.

METHOD: Refractive lens exchange with implantation of a toric diffractive multifocal lens (Acri.LISA toric, Zeiss/(*)Acritec) was performed on 10 eyes from 6 patients (age 25-57 years old). Preoperatively best corrected visual acuity varied between 0.5 and 1.0 in patients with astigmatisms between 1.5 and 5.75 dpt in combination with hyperopia (one patient) or myopia.

RESULTS

Postoperatively uncorrected visual acuity varied between 0.5 and 1.25 and best corrected visual acuity between 0.8 and 1.25. Postoperative refraction as spherical equivalent was 0 to +1.0 dpt with postoperative astigmatisms between 0 and 1.0 dpt. Rotational stability was found in all eyes, early postoperatively and also after 1 year. Patient satisfaction was very high.

CONCLUSIONS

The new toric multifocal lens is a new option in refractive surgery. The first results are very promising but further results and a comparison to the bioptics procedure have to be awaited.
