Clinical Performance Of The Extended Range Of Vision Intraocular Lens Vivity In Patients With Previous Corneal Laser Refractive Surgery

To evaluate the first clinical outcomes with a new model of extended range of vision intraocular lens (IOL) in eyes with previous corneal laser refractive surgery.

Prospective one-arm observational descriptive study enrolling a total of 24 eyes of 15 patients ranging in age from 46 to 76 years old. All of them had been operated on previously of corneal laser refractive surgery and underwent cataract surgery with implantation of the extended range of vision IOL Vivity from Alcon. Results in terms of uncorrected and corrected distance visual acuity (UDVA, CDVA), uncorrected and distance-corrected intermediate (UIVA, DCIVA) and near visual acuity (UNVA, DCNVA) and binocular defocus curve were evaluated during a 3-month follow-up.

At 3 months, mean UDVA and CDVA were 0.13±0.10 and 0.02±0.08 logMAR, respectively. Likewise, mean UIVA, DCIVA, UNVA and DCIVA were 0.05±0.10, 0.08±0.08, 0.13±0.08 and 0.23±0.08 logMAR, respectively. All eyes achieved a 3-month postoperative DCIVA of 20/32 or better. All these visual parameters experienced a significant improvement from 1 to 3 months postoperatively (p<0.05). Regarding the binocular defocus curve, visual acuity levels of 20/32 or better were found for the range of defocus from +0.50 to -2.00 D in all patients. A total of 66.7% of patients achieved at the end of the follow-up a complete spectacle independence.

The extended range of vision IOL Vivity can provide a successful distance, intermediate and near visual restoration in eyes with previous corneal laser refractive surgery.
