Abstract Details

Purpose:

To study binocular near, intermediate, distance vision and quality of vision after binocular implantation of toric trifocal IOLs.

Setting:

Single ophthalmology clinic.

Methods:

Patients were recruited after surgery and had a single diagnostic visit between 3 and 6 months after second-eye surgery. A total of 50 eyes of 25 subjects were included in the study. This study included both cataract and RLE eyes. Study subjects were implanted with toric trifocal Acri-Lisa from Carl Zeiss Medical in both eyes. Study subjects IOLs were tested for mon- and bin-ocular uncorrected and best distant corrected vision at near, intermediate and at distance. Moreover, we measured preferred reading distance and visual acuity at preferred reading distance. All study subjects answered a validated questionnaire addressing subjective visual quality.

Results:

Mean Spherical Equivalent (MSE) at the study visit was 0. 024 ± 0.52 D, ranging from -0.75 to + 1.25. Mean uncorrected distance vision (UCDVA) was 0.998 ± 0.152, ranging from 0.7 to 1.2. 75% of eyes had UCVA 1.0 or better. 89% of eyes had a uncorrected distance vision of 0.8 or better. Only 11% of eyes had a difference between UCVA and BCVA of more than 2 lines. Subjective assessment of Quality of Vision using a validated questionnaire showed significant optical side-effects, but subjective patient satisfaction was still very high.

Conclusions:

Implantation of toric trifocal IOLs in patients with significant corneal astigmatism and presbyopia were highly effective and safe. Both astigmatism and presbyopia could be treated with a high degree of patient satisfaction. Even though these patients did not end up with complete emmetropia, the high percentage of subjective patient satisfaction indicate that addressing astigmatism is highly appreciated among patients receiving MFIOLs.
