Comparison on Outcomes of Four IOLs in Patients With Cataracts

Comparison on Visual and Refractive Outcomes of Four Different Types of IOL in Patients With Cataracts

The objective of this study was to compare the objective visual outcomes and subjective fuctional vision of four different intraocular lens (IOL) in patients underwent cataracts surgery. This was a retrospective study. Patients with age-related cataract underwent phacoemulsification combined with IOLs implantation. Patients were divided into 4 groups. Uncorrected distant visual acuity(UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA),and the best corrected visual acuity (BCVA) 1 month and 3 months after the surgery were determined. The defocus curve, contrast sensitivity, and customized VF-14-oriented Visual Function Index questionnaire were performed 3 months postoperatively. Kruskal-Wallis test and generalized estimating equation(GEE) were used to analyze and compare the difference between objective visual outcomes and subjective visual quality among different groups.

This was a retrospective study. Patients with age-related cataract underwent phacoemulsification combined with IOLs implantation. Patients were divided into group A (TECNIS PCB00 IOL), Group B (HumanOptics Diff-Aay IOL), Group C (TECNIS Symfony ZXR00 IOL) and group D (ZEISS AT LISA tri 839MP IOL). Uncorrected distant visual acuity(UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA),and the best corrected visual acuity (BCVA) 1 month and 3 months after the surgery were determined.
