AT LISA® tri and AT LISA tri toric from ZEISS represent the next generation of ZEISS multifocal IOLs and are the first trifocal and trifocal toric preloaded true-MICS IOLs for True Living Vision. The near and intermediate additions of the ZEISS AT LISA tri 839MP and ZEISS AT LISA tri toric 939MP
INNOVATIVE TECHNOLOGY
Major studies on ZEISS AT LISA tri conducted from 2011 until today Visual acuity Clinical results show that the ZEISS AT LISA tri 839MP provides excellent intermediate visual acuity The monocular uncorrected and best distance corrected near and intermediate visual acuity Study showed excellent results for uncorrected intermediate vision at 66 cm and 80 cm Refraction Clinical results show that the ZEISS AT LISA tri 839MP provides very good post-operative refractive results. The predictability of the refractive results of the ZEISS AT LISA tri 839MP is excellent. Patient satisfaction The very good refractive outcomes are reflected in the results of the patient satisfaction evaluation in a study. After 6 months, 100 % of the patients were satisfied with their distance and intermediate vision and A high level of patient satisfaction was also reported in many studies. Low levels of halos (15 %) and glare (10 %) were found after 6 months in a study in 34 patients. This might contribute to the high level of patient satisfaction in most studies. Contrast sensitivity In our study, monocular photopic contrast sensitivity of 60 eyes was measured without Ocular Aberrations Total ocular aberrations were significantly reduced after surgery.
Clinical experience with ZEISS AT LISA tri toric 939MP The toric trifocal IOL is designed to make spectacle-free vision available to a broader group of patients. First clinical experiences with ZEISS AT LISA tri toric have confirmed an outstanding performance of this IOL. Reading acuity Subjective reading acuity, measured with the Salzburg Reading Desk was 0.11 logMAR at a preferred Rotational stability In all cases of the study the lenses were stable and within 5 degrees of the intended axis one month |
