One-Year Clinical Results and Quality of Vision After Implantation of Preloaded Trifocal IOL
Narrative Responses:
Purpose
To evaluate visual and optical performances of cataract eyes after phacoemulsification and trifocal Intraocular Lens (IOL) (AT LISA tri 839MP, Carl Zeiss Meditec) implantation.
Methods
21 eyes of 14 patients (7 female 7 male ( 7 bilateral implantation)) mean age: 69.52 ± 6.98 years underwent uncomplicated phacoemulsification and trifocal IOL (AT LISA tri839MP, Carl Zeiss Meditec) implantation. Preloaded IOL was implanted using a BLUEMIXS 180 injector. Postoperatively, the following visual and refractive parameters were measured: distance (5m) near (30cm) and intermediate (70 cm) visual acuity, corneal topography and aberrometry, contrast sensitivity and defocus curve. Regular follow-up examinations were performed up to 1 YEAR after surgery.
Results
Preoperative distance Uncorrected Visual Acuity (UCVA) was 0.32 ± 0.29. At 1 YEAR, distance UCVA was 0.95 ± 0.05, monocular near vision was 20/22 and binocular near vision 20/17.33( 17 bilateral implantation)
Monocular intermediate vision was 20/30.83, binocular intermediate vision 20/22.
Conclusion
AT LISA tri 839MP provided satisfactory distance and near as well as intermediate visual acuity. This lens also improved quality of vision through remarkable diffraction efficiency while maintaining contrast sensitivity.
