Abstract
Purpose: To assess visual performance and quality of life after implantation of diffractive trifocal IOLs with enhanced depth of focus (Acriva Reviol Tri-ED) compared to monofocal IOLs. Setting: Ophthalmology Clinic, Department of Medicine and Science of Ageing, University “G. d’Annunzio” Chieti-Pescara, Italy. Design: Prospective clinical study. Methods: This study comprised 36 eyes of 18 patients with senile cataract candidates for phacoemulsification and implantation of the Acriva Reviol Tri-ED (Group 1–18 eyes) and the AcrySof IQ Monofocal IOL SN60WF (Group 2–18 eyes). The main outcome measures, over a 6-month follow-up period, were uncorrected and corrected visual acuity at different distances (40, 60 cm and 4 m), defocus curve, contrast sensitivity and wavefront error. Patient satisfaction was evaluated by means of the NEI-RQL-42 questionnaire. Results: At 180 days postoperatively, the difference of the UCDVA and CDVA between the groups was not statistically significant (p = 0.888 and p = 0.843, respectively). The difference between the groups was statistically significant for UCIVA (p = 0.019) and UCNVA (p = 0.036). The mean values of contrast sensitivity under photopic and mesopic conditions were not significantly different between the groups. The RMS of spherical aberration was significantly lower in Group 1 compared to Group 2. The NEI-RQL-42 questionnaire showed statistically significant differences between the groups for the dependence on correction (p < 0.001). Conclusions: The diffractive trifocal IOL with enhanced depth of focus Acriva Reviol Tri-ED was effective in improving functional capacity for intermediate and near vision compared to monofocal IOLs and provided a good quality of vision due to a significant reduction in spherical aberration.
Highlights
The aim of intraocular lenses (IOLs) implantation is to provide a high quality of visual performance and to increase spectacle independence
While traditional multifocal IOLs (MIOLs) provide good near and distance vision but cause difficulty in intermediate vision, trifocal IOLs supply an improvement in intermediate vision without impairing distance and near visual acuity [1]
These results showed that the trifocal IOL used in this study is very effective in providing the al. [15]
Summary
The aim of intraocular lenses (IOLs) implantation is to provide a high quality of visual performance and to increase spectacle independence. While traditional MIOLs provide good near and distance vision but cause difficulty in intermediate vision, trifocal IOLs supply an improvement in intermediate vision without impairing distance and near visual acuity [1]. Technological advancements have been introduced to solve these issues: asphericity of the optics, apodization, refractive rotational asymmetry, lower addition for near vision, trifocal MIOLs, and enhanced depth of focus technology. These technological innovations partially or totally solve these concerns and improve quantity and quality of vision, increasing patient satisfaction and quality of life [2,3]
