Patient satisfaction after EDOF intraocular lens implantation in vitrectomized eyes

PURPOSE

To report patient satisfaction after unilateral/bilateral extended depth-of-focus (EDOF) intraocular lens (IOL) implantation in a young population after vitrectomy.

METHODS

Patients that underwent phaco-vitrectomy or phaco following vitrectomy with an AT LARA EDOF IOL, aged between 18 and 75 years, were asked to fill out a questionnaire to assess overall visual quality, near vision quality, and visual disturbances. The questionnaire was based on the Catquest, NAVQ, and APPLES questionnaires.

RESULTS

A total of 89 participants (average age 56.7 years) filled out the questionnaire of which 53.9% received a unilateral EDOF IOL. The most common indications for vitrectomy were retinal detachments (38.2%), floaters (36.0%), and epiretinal membranes (16.9%). The Catquest and NAVQ score respectively showed a good overall satisfaction (3.44/4.0), a good intermediate vision (3.55/4.0), and an average near vision (2.75/4.0). The APPLES score showed acceptable visual disturbances. There were no differences between the unilateral and bilateral group, except for a higher spectacle dependency in the unilateral group (40% vs. 10.6%). Participants that underwent vitrectomy in case of floaters reported lower satisfaction rates. Other variables, like the pre-operative refraction, had no impact on both satisfaction and visual disturbances.

CONCLUSION

Both unilateral and bilateral implantation of the AT LARA EDOF IOL showed a high satisfaction with no differences between both groups, except for a lower spectacle use in the latter. Hence, The AT LARA seems to be a possible choice in patients undergoing vitrectomy at a younger age, even for unilateral use.

Clinical Outcomes, Contrast Sensitivity, Reading Performance and Patient Satisfaction Following Bilateral Implantation of AT LARA 829MP EDoF IOLs

Purpose

To evaluate the visual outcomes, contrast sensitivity, reading performance and patient satisfaction after bilateral implantation of AT LARA extended depth of focus (EDoF) intraocular lenses (IOLs).

Methods

Patients undergoing phacoemulsification for age-related cataract and satisfying the eligibility criteria underwent bilateral implantation with AT LARA EDoF IOLs (Carl Zeiss Meditec, Jena, Germany). At follow-up visits of 1, 3, 6 and 12 months, binocular uncorrected and corrected distance, intermediate and near visual acuity, reading performance, defocus curve, contrast sensitivity and patient satisfaction for dysphotopsia and spectacle independence were evaluated.

Results

A total of 60 eyes from 30 patients with a mean age of 65.40±7.71 years were included in the study. At 12 months, 83% of patients (n=25) had binocular cumulative uncorrected distance visual acuity (UDVA) of 20/20 or better. Postoperative spherical equivalent refraction accuracy was within ±0.50 D for 95% of eyes (n=57) and refractive cylinder accuracy was within ≤0.50 D in 95% of eyes (n=57). The mean binocular uncorrected near visual acuity (UNVA) was 0.16±0.09 logMAR, and the mean uncorrected intermediate visual acuity (UIVA) at 60 and 80 cm was 0.01±0.09 and 0.03±0.08 logMAR, respectively, at 12 months. Reading speeds at 40, 60 and 80 cm showed improvement over time. No patient had complaints of severe dysphotopsia and none of the patients required glasses for any activity. No eye underwent YAG-laser capsulotomy for significant posterior capsule opacification at the end of mean follow-up.

Conclusion

In our limited experience of 30 patients at 12 months, AT LARA EDoF IOLs resulted in excellent visual outcomes for uncorrected distance, intermediate and near visual acuity. The incidence of dysphotopsia and spectacle dependence was low, resulting in good patient satisfaction.
