Abstract: Purpose: To evaluate the visual and refractive outcomes of a hydrophobic foldable extended depth of focus (EDOF) intraocular lens (IOL) following phacoemulsification. Methods: This prospective study included patients who underwent phacoemulsification with implantation of the extended depth of focus (EDOF) intraocular lens (IOL) between January 2023 and December 2023 at RGK Eye Care Center. Preoperative and postoperative visual acuity, refraction, and spectacle independence were assessed. The primary outcome measures were uncorrected distance visual acuity (UDVA) and uncorrected near visual acuity (UNVA). Postoperative follow-up was conducted at 1 month. Statistical analysis was performed using paired t-tests and chi-square tests to assess significance. Results: A total of 111 eyes from 111 patients (57 males, 54 females) were included. The mean age was 63.7 ? 9.6 years (range: 38?95). The mean UDVA improved significantly from preoperative values to postoperative values (p < 0.05). Postoperative UDVA outcomes were: 6/6 in 33.3% of patients, 6/9 in 31.5%, and 6/12 in 3.6%. Postoperative UNVA outcomes were: N5 in 10.8%, N6 in 71.2%, and N8 in 3.6%. Spectacle independence was achieved in 63.1% of patients for distance and 39.6% for near vision. Mean postoperative astigmatism was 0.38 ? 0.33 D. No significant complications were observed. Conclusion: The extended depth of focus (EDOF) intraocular lens (IOL)demonstrated excellent visual outcomes, with significant improvement in UDVA and UNVA, and a high rate of spectacle independence. These findings are consistent with previous studies evaluating EDOF IOLs [1,2].
