2020 paper presentation
Purpose
To report an overview of the optical characteristics and clinical performance of a new trifocal Enlighten IOL over a one year period, treating presbyopia concurrent with cataract surgery.
Methods
Prospective, consecutive adult patients undergoing bilateral cataract surgery with bilateral implantation of the study IOL, in a private practice in El Salvador. A total of 20 eyes in 10 patients underwent: monocular defocus curve; monocular and binocular uncorrected visual acuity in photopic and mesonic conditions, for far (4m), intermediate (60 cm) and near (33 cm) distances and binocular contrast sensitivity. Patients completes a one month, 3 months, 6 months and 12 months follow up after surgery.
Results
20 eyes of 10 patients were analyzed. Mean binocular uncorrected visual acuity in photopic conditions was 0.03 LogMAR for far, 0.12 for intermediate and 0.02 for near distances. All patients achieved a binocular uncorrected visual acuity better than 0.3 LogMAR (20/30 Snellen) for distance and near vision and 94.8% of patients for intermediate vision. Mesopic bioncular visual acuity values were similar. Monocular defocus curves showed best visual acuity at a vergence of 0.00D. 94.8% of the patients reportes never using spectacle correction.
Conclusion
This new trifocal Enlighten IOL achieved excellent uncorrected distance, intermediate and near vision without compromising the quality of vision. The similar values achieved in mesonic and photopic conditions of binocular uncorrected visual acuity and contrast sensitivity suggest low pupillary dependence for light distribution.
