Abstract

   

Aim of the study was to find out whether the implantation of the multifocal lenses, can be recommended categorically, to expect a good spectacle-free vision in cataract patients.

Materials and Methods: consisted of a prospective study in which 50 eyes of cataract patients were implanted with multifocal lenses. Criteria like visual improvement, spectacle-free vision, glare, diplopia and de-centration of the lens were used, to assess the result of this prospective study.

Conclusion: The study undoubtedly concluded that implantation of multifocal can be recommended, to expect post-operatively in cataract patients a spectacle-free 6/6 and N5 vision, with a condition that the lens should be heparin surface modified lens, as in our study more than 90% of the patients achieved unaided 6/6 vision and unaided N5 of near vision.
