Abstract:

Objective To compare visual performance of two types of rotationally asymmetric segmental-refractive multifocal intraocular lens (IOL). Design Retrospective case series. Participants 40 cases of cataract which got phacoemulsification combined with two types of rotationally asymmetric segmental-refractive multifocal intraocular lens implantation in Beijing Tongren Eye Center from October, 2015 to May, 2016. Methods Two types of rotationally asymmetric segmental-refractive multifocal IOL were implanted in capsular bags after phacoemulsification for cataract patients. A total of 40 patients (40 eyes) were analyzed with 20 patients (20 eyes) in each group. Three months postoperatively, the uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), corrected distance visual acuity (CDVA), corrected intermediate visual acuity (CIVA), corrected near visual acuity (CNVA), refractive power, and subjective symptom questionnaires were compared. Main Outcome Measures UDVA, UIVA, UNVA, CDVA, CIVA, CNVA, refractive power, subjective symptom questionnaires. Results Three months postoperatively, no significant differences in UDVA, CDVA, UIVA, CIVA or CNVA were found between the two groups (all P>0.05). The UNVA of MF 30 group was 0.26±0.14 (Logmar)，and the UNVA of MF 15 group was 0.36±0.13 (Logmar). The UNVA of MF 30 group was significantly better than MF 15 group (P=0.03). The subjective symptom questionnaire also did not demonstrate any significant differences (P>0.05). Conclusions Rotational asymmetric regional refractive multifocal intraocular lens MF 30 can get better near vision than MF15. (Ophthalmol CHN, 2017, 26: 248-252)
