Self-rated quality of vision and optical phenomena intensity of diffractive presbyopia-correcting IOLs: EDoF, trifocal vs panfocal.

PURPOSE: To investigate the self-rated quality of vision (SQV) and optical phenomena intensity of 3 diffractive multifocal intraocular lenses (mIOLs).

SETTING

Department of Ophthalmology, Goethe University Frankfurt, Germany.

DESIGN

Prospective comparative case series.

METHODS

Patients who had bilateral implantation of a diffractive extended depth-of-focus (EDoF), trifocal, or panfocal mIOL were assessed. Outcome parameters were SQV, symptom intensity of optical phenomena under 3 lighting conditions, quality of everyday lifestyle activities, spectacle independence (SI), and contrast sensitivity (CS).

RESULTS

The study comprised 108 eyes. The 3 lenses provided good total SQV under all lighting conditions. EDoF patients reported a slightly better total SQV (EDoF: 9.8 ± 6.67, trifocal: 22.2 ± 7.09, panfocal: 19.6 ± 16.25 visual analog scale, P = .041). A similar percentage of patients reported the presence of optical phenomena with no difference between mIOLs ( P > .05). EDoF, trifocal, and panfocal patients rated symptom intensity of optical phenomena mild to moderate under all lighting conditions; however, EDoF patients reported a lower symptom intensity of halos ( P < .05). Reported quality of everyday lifestyle activities and CS were comparable ( P < .05). All panfocal and trifocal patients (100%) achieved complete SI, whereas almost half (44%) of the EDoF patients used reading spectacles.

CONCLUSIONS

Diffractive EDoF, trifocal, and panfocal mIOLs provided good total SQV with mild to moderate intensity of optical phenomena under all lighting conditions. EDoF patients experienced the same percentage of optical phenomena but reported a weaker symptom intensity of halos and better night-driving ability. EDoF patients would all choose the same IOL, although a significant number of them needed reading spectacles, indicating that SI is not the main factor that determines patient selection of IOLs.
