Extended Depth Of Focus (Edof) Intraocular Lenses In Patients With Ocular Comorbidities

To evaluate the visual outcomes of Extended Depth of Focus (EDOF) intraocular lenses (IOLs) in patients with pre-existing ocular comorbidities. Patients with a history of retinal detachment surgery or macular hole repair may experience altered macular function, potentially affecting postoperative vision. Similarly, those with previous corneal refractive surgery require careful preoperative assessment to ensure appropriate lens power calculations. In cases of glaucoma, where contrast sensitivity is already compromised, EDOF lenses may still be a viable option but should be carefully considered in advanced disease stages.

This study included 10 patients who underwent EDOF IOL implantation. All patients had a history of one or more ocular comorbidities, including previous macular hole surgery, previous laser retinopexy for retinal breaks, previous retinal detachment surgery, previous corneal refractive surgery, glaucoma, and age-related macular degeneration. Postoperative evaluations included measurements of uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA), corrected near visual acuity (CNVA), and contrast sensitivity. The follow-up period extended over 12 months.

Postoperative UDVA, CDVA, UNVA, CNVA, contrast sensitivity and glare were analyzed in all patients. The mean postoperative UDVA was 20/25, while the mean CDVA was 20/20. Mean postoperative UNVA was j2 and CNVA was j1. Mean contrast sensitivity score was 7, and mean glare score was 8. All values remained unchanged during the entire follow-up period.

Despite the advantages of improved intermediate vision and reduced dependence on spectacles, challenges remain in optimizing outcomes for patients with ocular comorbidities. Future research should focus on refining patient selection criteria and developing strategies to enhance visual quality in these individuals. Understanding the interplay between EDOF technology and ocular disease is crucial for achieving optimal postoperative satisfaction and visual function in this patient population.
