Abstract

Objective  To compare pseudoaccommodation after cataract phacoemulsification combined with the implantation of different intraocular lenses (IOLs). Methods  In a prospective study, 73 patients (82 eyes) who had received IOL implants after cataract extraction were divided into three groups according to the implanted IOL: group 1, monofocal IOL, 28 patients, 32 eyes; group 2, multifocal IOL, 24 patients, 27 eyes; and group 3, accommodative IOL, 21 patients, 23 eyes. The uncorrected distance, intermediate and near visual acuity; best-corrected distance and near visual acuity; and pseudoaccommodation (respectively measured by Integrated Refractometer and iTrace Visual Function Analyzer 3.1) were measured. The data were collected at 3, 7, 30 and 90 days after surgery, and analyzed by a single-factor analysis of variance. Results  The differences in the best-corrected distance visual acuity, near visual acuity and uncorrected distance visual acuity was not statistically significant, while uncorrected intermediate distance visual acuity of group 3 was better than groups 1 and 2 (F=4.50, P<0.05). The near visual acuity of groups 2 and 3 was better than group 1 (F=26.06, P<0.05). Subjective pseudoaccommodation of group 2 was 2.67±0.49 D and objective pseudoaccommodation was 0.93±0.42 D. Subjective pseudoaccommodation of group 3 was 3.0±0.78 D and objective pseudoaccommodation was 0.91±0.58 D. Both groups had better pseudoaccommodation than group 1 with 1.78±0.26 D for subjective pseudoaccommodation (F=18.51, P<0.05) and 0.37±0.22 D for objective pseudoaccommodation (F=7.39, P<0.05). Conclusion  Multifocal and accommodative IOLs can temporarily provide better visual acuity and pseudoaccommodation.
