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.

Postoperative visual acuity
The uncorrected distant visual acuity(UDVA), the best corrected distant visual acuity (BCVA) (5 m), the uncorrected intermediate visual acuity(UIVA) (80 cm) and the uncorrected near visual acuity(UIVA) (40 cm) were chosen as the index to evaluate the VA. The UDVA and BCVA were examined by logarithmic visual acuity chart. The UIVA and UIVA were examined by using a near eye chart.They were all measured 1 month and 3 months after the surgery.
Time frame: 3 months
Postoperative contrast sensitivity
The contrast sensitivity was used to conduct the assessment by CSV-1000E (VectorVision, USA) under photopic (85 cd/m2) condition at a 2.5m distance. The logarithmic values for 3, 6, 12, and 18 cycles/degree (c/d) were analyzed 3 months postoperatively.
Time frame: 3 months
Postoperative defocus curve
Defocus curve was used to evaluate the visual quality of functional intraocular lens after surgery. The insertion range was -4.0 D \~ + 2.0 D, increasing by 0.5 D. The best corrected distant visual acuity was recorded at each diopter 3 months postoperatively.
Time frame: 3 months
Postoperative eye-related quality of life
Based on the American Questionnaire on Visual Function Index-14 (VF-14), the Chinese-oriented version(VF-12-CN) was used to investigate the postoperative near-vision, visual satisfaction, ocular discomfort, visual disturbance, and subjective feelings of far-vision, middle-vision and near-vision. Each question was divided into 4 levels and the scores ranked from 0 to 3 points. Considering the visual interference such as glare and halo, the evaluation of glare and halo visual interference phenomenon was also added.
Time frame: 3 months after surgery
