Purpose:
To compare the visual outcome findings between a new monofocal intraocular lens (IOL) (Tecnis Eyhance) and extended depth of focus (EDOF) IOL (Appasamy Supraphob Infocus).
Methods:
This prospective comparative interventional study evaluated 31 patients after implantation of Tecnis Eyhance (15 patients) and Supraphob EDOF IOL (16 patients). The uncorrected and corrected distance and intermediate and near visual acuity were measured at postoperative day 1, 1 week, 4 week, and 3 months. Contrast sensitivity, incidence of halos and glares, and patient satisfaction were assessed at 3 months postoperatively.
Results:
The Tecnis Eyhance (n = 15) and Supraphob EDOF (n = 16) group were comparable with respect to all preoperative parameters including biometry, visual acuity, and cataract status. The average age distribution of participants was 56 ± 6 years. Postoperatively, both groups had similar distance and intermediate vision, but the near vision was significantly better in the EDOF group (P < 0.01) as compared to Tecnis Eyhance at 3 months. The contrast sensitivity and patient satisfaction were similar in both the groups. The incidence of halos and glares was present in the EDOF group, but it was statistically insignificant.
Conclusion:
The Tecnis Eyhance and Supraphob EDOF both were effective in improving distance and intermediate vision, but the near vision was significantly better in the EDOF group. Both the groups retained good contrast sensitivity and the majority of patients were satisfied.
