Abstract Details

Purpose:

To evaluate long-term results of presbyopic lens exchange (PRELEX) with trifocal intraocular lens (IOL) regarding to objective visual quality, contrast sensitivity, subjective performance, laser capsulotomies and laser enhancements.

Setting:

Neovize Eye Clinic, Brno, Czech Republic

Methods:

Retrospective study randomly selected 60 patients after binocular PRELEX with  implantation of trifocal IOL, AT LISA® tri 839 MP (30 patients) and PanOptix®(30 patients) was performed 30-36 months after surgery. Uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), corrected distance visual acuity (CDVA), and distance corrected near visual acuity (DCNVA) was determined binocularly. Contrast sensitivity was determined under photopic and mesopic conditions. Subjective satisfaction with near and intermediate vision was evaluated using standardized Near Activity Visual Questionnaire (NAVQ). Number of laser capsulotomies and laser enhancements were also assessed.

Results:

Mean binocular UDVA was 0.10±0.14 log MAR (AT LISA® tri) and 0.12±0.12 (PanOptix®), mean binocular CDVA was -0.08±0.09 (AT LISA® tri) and -0.09±0.08 (PanOptix®), mean DCNVA was 0.07±0.10 (AT LISA® tri) and 0.08±0.12 (PanOptix®). Contrast sensitivity was similar in both group. Subjective satisfaction expressed by Rasch score was high - AT LISA® tri group (18.59), Pan Optix® group (19.51). Higher rate of YAG laser capsulotomies were found in AT LISA® tri group (18%) comparing to PanOptix® group (2,4%). Laser enhancement was performed in 5 eyes with AT LISA® tri, and in 1 eye with PanOptix®.

Conclusions:

Long-term results of PRELEX surgery with two types of diffractive trifocal IOLs proved stable level of visual functions and high subjective satisfaction. Higher rate of YAG laser capsulotomies in AT LISA® tri 893 MP group probably depends on material of trifocal IOL. The amount of laser enhancements were insignificant in our study group.
