Abstract Details

Purpose:

Bifocal and Trifocal IOLs have the advantage of spectacle independence, but patient might complain of halos and glare. IOLs with extended range of vision have the advantage of low visual disturbance, but need some degree of monovision for spectacle independence

Setting:

Universitäts-Augenklinik Graz Sehzentrum für Augenlaser und Augenchirurgie

Methods:

32 Patients (64 eyes) with or without cataract underwent uncomplicated phakoemulsification with IOL (Oculentis Comfort, Oculentis, Germany) implantation. Both eyes were operated on the same day or within 7 days of delay. The average age of the patients was 72,9 ± 13 years. The average power of implanted IOL was 24,45 ± 5,35 D. Target refraction was emmetropia in the dominant and -0,75 ± 0.3 D in the non-dominant eye. Visual tests included UDVA, CDVA, UNVA, CNVA. All test were performed 3 to 6 months after IOL implantation. If the target refraction was not achieved, the patient underwent LASIK.

Results:

56 eyes were within the target refraction ± 0.5D. All patients had a binocular UDVA of 0.0 logMAR. The UDVA of the dominant eye was 0.0 logMAR and that of the non-dominant eye 0.4 - 0.2 logMAR. Binocular uncorrected near visual acuity was 0.4 - 0.7 decimal. Only 2 patients complained needing reading glasses when studying newspaper. All patients were happy with their distance and intermediate vision and 28 out of 32 patients never used reading glasses. 5 patients complained about halos at night, which dissolved when the patient was corrected for the non-dominant eye.

Conclusions:

Mini-monovision with extended depth of field IOLs and anisometropia of 1 D gives a good spectacle independence for all distances for the majority of patients. In cases of halos at night, the patient can be spectacle corrected for night driving.
