Abstract Details

Purpose:

To evaluate visual outcomes of a segmental refractive multifocal intraocular lens (LENTIS® Mplus X LS-313 MF 30) after cataract surgery at a three month follow-up examination.

Setting:

Department of Ophthalmology, Goethe University, Frankfurt, Germany.

Methods:

Twenty-two eyes of eleven patients were included in this prospective study. Distance, intermediate (80cm) and near (40cm) visual acuity, contrast sensitivity (CS) (Optec 6500), reading skills (Radner Reading Charts), defocus curves and a questionnaire of subjective quality of vision, optical phenomena and spectacle independence were evaluated 3 months after surgery. Inclusion criteria were bilateral cataract, age >45 years, corneal astigmatism <0.75D postoperatively, pupil size 3 to 6 mm (mesopic), center shift <1mm (Pentacam HR). Patients who had refractive surgery, irregular astigmatism, strabismus, amblyopia, ocular surgery other than cataract surgery or potential postoperative BCDVA worse than 0.3 logMAR were excluded.

Results:

The mean postoperative monocular uncorrected visual acuity (logMAR) was 0.06±0.14 logMAR at distance, 0.20±0.19 logMAR at 80cm and 0.13±0.12 logMAR at 40cm. Distance corrected visual acuity was -0.03±0.10 logMAR at distance, 0.17±0.21 logMAR at 80cm and 0.11±0.13 logMAR at 40cm. All included patients reported independence of spectacles after surgery. The mean patient satisfaction (scale 0, satisfied to 100, dissatisfied) was 10.9±9.8 (photopic) and 25.0±18.0 (mesopic). The CS at 6 cycles per degree under photopic conditions was 1.77±0.22 logCS without glare, 1.62±1.85 logCS with glare and under mesopic conditions 1.30±0.49 logCS without glare and 0.73±0.70 logCS with glare.

Conclusions:

This multifocal IOL provides good distance (<0.1 logMAR), intermediate and near visual acuity. None of the patients needed spectacles three months postoperatively. Contrast sensitivity was shown to be good during daytime with and without glare. Patients were satisfied after cataract surgery.
