The aim of the study was to compare the postoperative quality of vision among patients who underwent monofocal or enhanced depth of focus (EDOF) intraocular lens (IOL) implantation after ultrasound phacoemulsification cataract surgery (PHACO).
The prospective cohort study enrolled 61 patients of both gender with cataract who underwent PHACO. Exclusion criteria were pre-existing irregular astigmatism, ocular surface disease, previous keratoplasty, refractive surgery or any ocular surgery, ocular surface disease and keratoconus, traumatic corneal scars, diabetic patients, posterior segment diseases, maculopathy, previous or active uveitis that could compromise postoperative best corrected visual acuity (BCVA).
The first group of 31 patients included those with monofocal IOL (Tecnis ZCB00) implanted and the second group of 30 patients were those with EDOF IOL (Tecnis Eyhence) implanted during PHACO. All patients underwent full ophthalmic examination, corneal fluorescein staining, tear film break-up time test (TBUT), contrast sensitivity test (CS), residual astigmatism and visual acuity (VA) assessment on the day of the surgery and 30 days after the surgery. The difference in distance and near BCVA before and after the cataract surgery were examined as well as CS and residual astigmatism. All patients underwent PHACO followed by IOL implantation performed by the same surgeon on Centurion device (Centurion Alcon 2022).
The mean age of patients was 72 ± 12. (females 51% versus male 49%, with no statistically significant difference between gender (Fisher exact test, p-value =0.72). In both groups of patients distance and near BCVA was improved after PHACO (Wilcoxon test, p<0.001) with preoperative distance median BCVA 0,5 ± 0,3 and postoperative BCVA 1,0 (-0,1) (Wilcoxon test, p<0,001) in monofocal IOL group while in EDOF group preoperative distance median BCVA was 0,3 ± 0,1 and postoperative BCVA 1,0 (-0,1) (Wilcoxon test, p<0,001). In monofocal IOL group, 47% of patients could read Jager 4 probably due to pseudoaccomodation while in EDOF group, 87 % of patients reached Jeger 1-2 and had no problems with reading.
There was no difference between residual astigmatism in both groups of patients before and after PHACO (p=0.29, p=0.70). The CS was worse in the EDOF group than in monofocal group (p < 0.05). No one patient mentioned glare and halloes.
The present study has shown that both IOLs provide good distance vision. EDOF IOL provides good distance and intermediate vision without halloes and glare which is important in night driving. However, some patients will still need reading glasses when doing some precise near jobs. With EDOF IOL they feel more comfortable as they can clearly see at communication distance and can fulfil the majority of daily obligations without spectacles.
