Refractive outcome and patient satisfaction after cataract surgery with mutifocal intraocular lens implantation

Abstract

Purpose: Assessing the recovery of visual acuity (VA) with and without correction and evaluating the patient's satisfaction after cataract surgery and implantation of diffractive multifocal implants AT LISA® 809M (Carl Zeiss Meditec, Goeschwitzer, Germany).

Methods: Retrospective cohort study including 52 eyes of 42 patients with cataracts and a motivation for a spectacle independency after surgery . All patients have been operated by the same experimented surgeon between January 2012 and November 2012. Uncorrected distance (UDVA) and near (UNVA) visual acuities,overall satisfaction,and spectacle independency were evaluated. Global satisfaction was studied by a visual quality of life questionnaire that consist of 5 criteria: news paper reading, computer work, driving night comfort, watching TV and the perception of moving objects. Those 5 aspects were rated from 1 to 5 (from very unsatisfied to very satisfied).

Results: One month after surgery, the mean UDVA increased significantly from 0.83+/-0.44 to 0.12+/-0.09(p<0.001).The mean distance gain was 7.1 lines.The UDVA was more than 0.8(20/25) in 78% of patients.The mean UNVA was 0.21 logmar+/-0.08 with a mean near gain of 4.7 lines.The UNVA was Jeager 1 in 82% of patients.Eighty five percent of patients became completely independent to glasses. Global satisfaction was 85%, in which more than a half were very satisfied ( mean global satisfaction score was 22.22+/-2.95). Seventy three percent of patients easily read newspaper without any correction and 75% who felt comfort watching television were very satisfied. Only one patient encountered problems while driving at night. Finally, 85% worked easily on a computer and no perception disorder due to moving objects have been described.

Conclusions: In our study, refractive results after phacoemulsofication and multifocal IOL implantation were generally effective, predictive and safe, without major dissatisfaction described concerning the quality of life.
