Comparative Compliance Of Patients After Implantation Of Different Types Of Multifocal Iols

To compare visual outcomes after implantation of three models of trifocal diffractive intraocular lenses (IOLs) and a deep-focus monofocal lens using various vision assessment systems.

A total of 106 patients without severe somatic pathology and accompanying eye diseases were selected.

The first group included 25 patients (40 eyes) - Liberty multifocal IOL . The second group consisted of 24 patients (40 eyes) - Tecnis Synergy multifocal IOL , the third group consisted of 27 patients (40 eyes) with the monofocal deep focus lens Tecnis Eyhance  and the fourth group consisted of 30 patients (40 eyes) with the Panoptix multifocal IOL. 

The following tests were conducted to assess the postoperative condition: visual acuity at distances of 5 m, 80 cm, 60 cm, 40 cm, and 30 cm.

To assess patient satisfaction with their vision in the postoperative period, a questionnaire consisting of 7 questions was used:

How often were you bothered by glare? How often did you notice halos? Are you satisfied with the quality of your vision at different focal distances? How often did you experience poor vision in low light conditions? How often did you have difficulty focusing? Do you have to wear glasses periodically?How often did you have difficulty judging distance or depth perception?

(0 - no manifestation, 1 - mild manifestation, 2 - frequent manifestation, 3 - very frequent manifestation.)

Visual acuity above 0.9 at near (30 cm) and distance (5 m) was detected in 101 patients (95.1%).The mean visual acuity at a distance of 80 cm was 0.6±0.21.

The frequency of glare occurrence was:AcrySof PANOPTIX (20 points - rare,10 points - frequent),Liberty -(6 - rare,12 - frequent and 9 points - very frequent) and Tecnis Synergy -(11 - rare,4 points - frequent).

The frequency of halo occurrence was:AcrySof PANOPTIX - (10 points - rare,30 - very frequent),Liberty -(5 points - rare,45 - very frequent) and Tecnis Synergy -(5 - rare,9 points - very frequent).

Worsening of vision in twilight was noted in 58.6% of patients, however, this was of concern to 13.9% of the subjects due to the low intensity of the symptom, which was manifested in 19.1%.

The visual acuity at far, intermediate, and near distances measured by using visometry at distances of 5 m, 80 cm, 60 cm, 40 cm, and 30 cm was higher in the Tecnis SYNERGY group compared to the other three groups.

When using three models of trifocal IOLs and a deep focus monofocal lens, we observed high levels of subjective satisfaction with the quality of vision at all distances, which was 92.5% in the Tecnis SYNERGY group, 90.85% in the Liberty group, 89.5% in the Panoptix group, and 85.90% in the Tecnis Eyhance group. Postoperative glasses correction was lower in the Tecnis SYNERGY group (3.6%) and in the group of patients implanted with Liberty 677MY (4.5%) compared to the other groups (10.1%).
