Purpose
To evaluate the clinical outcomes after cataract surgery with the implantation of a new extended-depth-of-focus (EDOF) intraocular lens (IOL) (Alcon AcrySof IQ Vivity) in extreme cases (eyes with previous corneal refractive surgery and keratoconus).
Setting
Methods
In a prospective case series, 14 eyes of 7 patients undergoing cataract surgery with AcrySof IQ Vivity implantation were enrolled: 4 patients with previous myopic LASIK, 2 patients with previous hyperopic LASIK and 1 patient with keratoconus. The outcomes in terms of distance, intermediate and near visual acuity (VA), refraction, defocus curve, photic phenomena and spectacle independence were evaluated at 3-months follow-up.
Results
Monocular uncorrected distance VA and distance-corrected intermediate and near VA improved in all the patients. Refractive results were good, with 10 of the 14 eyes with 0.50 D of the target. A functional VA of 0.3 LogMAR or better was obtained in all the patients for vergence demands of +0.50 to -3.00 D. The frequency, severity and bothersomeness of different visual symptoms, including glare and haloes was low. After surgery, none of the patients required the use of spectacles for any distance.
Conclusion
The EDOF IOL studied provided an effective visual rehabilitation, resulting in an improved distance, intermediate and near VA, low prevalence of photic phenomena and high spectacle independence. Even in selected extreme cases, EDOF IOLs may be an effective alternative to standard monofocal IOLs.
