Abstract Details


Following cataract surgery, postoperative presbyopia remains a challenge. Accommodative IOLs have been developed to overcome loss of accommodation after intra-ocular lens implantation.To evaluate the interest of optimized -power accomodative implants in cataract surgery.


Centre Hospitalier National d'Ophtalmologie des Quinze-Vingts Paris-France


20 eyes of 15 patients underwent phacoemulsification cataract surgery with the implementation of an accommodative implant with optimized power (group 1). The refractive outcome of 20 eyes from 17 patients who underwent cataract surgery with placement of a standard emmetropic monofocal implant (group 2) was also evaluated and compared to group 1. Refractive and visual acuity results, objective measurement of the accommodation amplitude by the HD Analyzer system and partial coherence interferometry (IOLMaster®, Carl Zeiss) optical movements ACD (anterior chamber depth), as well as patient satisfaction, were analyzed.


Best distance visual acuity without correction was 0.97 ± 0.04 in group 1 versus 0.79 ± 0.11 in group 2. In intermediate and near-visions without correction, average visual acuity was better in group 1 compared to group 2. Absolute refractive error was 0.03 ± 0.06D in group 1 versus 0.20 ± 0.21D in group 2. Objective refraction ranged from -0.25D to + 0.25D in 90% in group 1 versus 64% of the eyes in group 2. Similarly, 96% and 75% of patients reported not being dependent on glasses in group 1 and 2 respectively.


Optimized power-optimized accomodation implants with 0.01D would have good visual and refractive results, with good patient satisfaction.
