Purpose
To evaluate the visual outcome and quality of vision in patients undergoing cataract surgery with implantation of purely refractive extended depth of focus intra-ocular lens.
Setting
This prospective study was conducted at tertiary eye hospital on 50 patients undergoing phacoemulsification with extended depth of focus intraocular lens.
The tenets of the Declaration of Helsinki were followed, and institutional ethics approval was obtained from the ethics committee. Informed consent was obtained from all patients before the procedure.
Methods
in this prospective study 50 patients ( 50 eyes) underwent phacoemulsification with purely refractive extended depth of focus intraocular lens. patients with immature senile cataract with normal fundus examination were included in the study while patients with any history of ocular trauma, pupillary abnormalities, any ocular anomaly and retinopathy were excluded from the study. Uncorrected visual acuity for distance, intermediate distance were recorded on day 1, day 7 and 1 month post operatively. and patient satisfaction was evaulated by filling of the forms.
Results
After the surgery on day 1 uncorrected distance visual acuity was 0. 21 logmar and improved to 0.06 logmar at one month. uncorrected visual acuity for intermediate distance recorded was 0.16 logmar. 10 percent of patients reported moderate glare and halos with none reporting severe dysphotopsia. 90% of patients achieved a refractive outcome within ± 0.50 dioptres of the intended target,. Patient's satisfaction was high while reducing spectacle dependence.
Conclusions
in our study, Purely refractive extended depth of focus intraocular lens provided excellent distance visual acuity with good intermediate distance while maintaining quality of vision by reducing dysphotosias and spectacle dependence. These IOls tend to bridge the gap between monofocals and multifocal IOls by providing extended range of vison. These EDOF IOLs are next generation IOLs with purely refractive design to provide increased range of vision for intermediate distance while having good distance vision and minmal dysphotopsia and spectacle dependence
