Abstract Details

Purpose:

To evaluate the long-term refractive stability and patient satisfaction after bilateral implantation of trifocal intraocular lenses (IOLs).

Setting:

Clinical

Methods:

The medical records of the patients who underwent bilateral cataract surgery with AT LISA tri IOL (Zeiss, AT LISA® Tri 839MP) implantation and were followed up more than 12 months were reviewed. The MAE (mean average error) at one month and one year after surgery were calculated, and visual symptoms and satisfaction scores were evaluated. According to the presence of visual symptoms including glare, halo and starburst, patients were divided into three groups for each symptom (group1: none, group2: sometimes have, group3: always have), and kappa distance, photopic angle kappa, and mesopic angle kappa were compared among three groups.

Results:

Thirty two eyes of 16 patients were included. The MAE was -0.04±0.11 at one month, and 0.11±0.36 at one year. 85.3% of patients were were satisfied after IOL implantation. Glare and starburst were the most annoying symptoms that unsatisfied patients complained of. Three groups (group1: none, group2: sometimes have, group3: always have) for glare, halo, and starburst showed no significant difference in kappa distance (p=0.312 for glare, p=0.152 for halo, p=0.701 for starburst), photopic angle kappa (p=0.832 for glare, p=0.380 for halo, p=0.230 for starburst), and mesopic angle kappa (p=0.430 for glare, p=0.125 for halo, p=0.147 for starburst).

Conclusions:

The AT LISA tri IOL showed excellent long term refractive predictability, stability, and high satisfaction. Glare and starburst were two visual symptoms not well-tolerated by unsatisfied patients, and the position of pupil was not related with visual symptoms.
