About this study

Official title: 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.

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 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. 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: 3 months

  2. 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.

    Measured: 3 months

  3. 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.

    Measured: 3 months

  4. 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.

    Measured: 3 months after surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Cataract and Intraocular Lens, run by Shanghai 10th People's Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Postoperative visual acuity (time frame: 3 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Sep 2024.
