Visual Results In Patients Who Undergone Bilateral Phacoemulsification With Vivity Lens And Istent Inject W Implant

To study the visual results in patients operated on using a Vivity® intraocular lens and I-Stent inject® implant bilaterally and simultaneously.

Patients with ocular hypertension or glaucoma who underwent surgery for bilateral cataract with implantation of a Vivity intraocular lens in both eyes and simultaneously injection of i-Stent in at least one eye, with a minimum follow-up of 1 year, were identified.

Prior to cataract surgery, patients in our clinic undergo a comprehensive evaluation included binocular uncorrected visual acuity for distance, intermediate (66 cm) and near (40 cm) distances and binocular distance corrected contrast sensitivity.

Patients were then asked to answer a questionnaire of an estimation of their spectacle use under good and low lighting conditions for distance, intermediate and near distances, the incidence of halos and glare, their difficulties when driving at night and the Catquest-9 questionnaire.

In order to compare visual outcomes and patient satisfaction with subjects with no ocular pathology, a historical group of patients bilaterally implanted with a Vivity intraocular lens in our center was used. 

68 patients were included in the study and their mean age was 72.58 years. The diagnosis of the 134 eyes included was primary open-angle glaucoma in 76 eyes, OHT in 28 eyes and pseudoexfoliation with glaucoma in 23 eyes.

The mean visual acuity in LogMar went from 0.25 corrected before surgery to uncorrected post-surgery acuities of -0.03 in distance vision, 0.09 in intermediate and 0.17 in near. The mean spherical equivalent after surgery was -0.11D. Contrast sensitivity satisfaction was also high.

Intraocular pressure decreased by an average of 15.38% per year after surgery and by 12.50% at the end of follow-up. The number of hypotensive drugs went from 1.82 before surgery to 0.22 at one year of follow-up.

Visual results were very good, with mean binocular uncorrected visual acuities better than 0.2 from distance to near vision. Satisfaction with visual function was high, as reported by patients in the Catquest questionnaire, with low difficulties for performing daily activities. Almost half the patients reported that with good light, they never required spectacle correction for near distance. The study group compared favorably with a historical cohort of patients with no ocular pathology implanted with a Vivity IOL with almost no differences.

Cataract intervention with Vivity® lens associated with the placement of I-Stent Inject® implant is a safe and effective option.
