# Comparative Study of Two Multifocal Intraocular Lens With Different Add Power

**NCT ID:** [NCT02424162](https://clinicaltrials.gov/study/NCT02424162)

## Key Facts

- **Status:** COMPLETED
- **Phase:** NA
- **Study Type:** INTERVENTIONAL
- **Target Enrollment:** 43
- **Lead Sponsor:** Yonsei University
- **Conditions:** Cataract
- **Start Date:** 2014-11-11
- **Completion Date:** 2015-11-03
- **CT.gov Last Update:** 2019-02-18

## Brief Summary

This study will compare cataract patients with implantation of diffractive multifocal IOL with an additional power of +2.75 diopters (Group 1) and with +3.25 diopters (Group 2). Evaluations will be performed 1 and 3 months following cataract surgery, including measurement of uncorrected distance visual acuity (UDVA), refractive error (manifest refraction \[MR\]), and uncorrected near visual acuity (UNVA) at 33, 40, and 50 cm. At 3 months, internal aberrations and contrast sensitivity will be evaluated and subjects will complete a questionnaire on outcomes satisfaction, visual symptoms, and spectacle use.

## Eligibility

- **Minimum age:** 18 Years
- **Maximum age:** 80 Years
- **Sex:** ALL
- **Healthy Volunteers:** No

```
Inclusion Criteria:

* age \>= 18
* cataract patients with lens opacities classification higher than grade III
* patients who desire to be spectacle indepence for distance and near vision

Exclusion Criteria:

* previous ocular surgery or trauma
* presence of corneal opacities
* fundus abnormalities
* glaucoma
* uveitis
* amblyopia
* systemic disease
* posterior capsule rupture during cataract surgery
```

## Arms

- **2.75 group** (EXPERIMENTAL) — Patients with 2.75 diopters multifocal intraocular lens
- **3.25 group** (ACTIVE_COMPARATOR) — Patients with +3.25 diopters multifocal intraocular lens

## Interventions

- **+2.75 diopters multifocal intraocular lens** (DEVICE)
- **+3.25 diopters multifocal intraocular lens** (DEVICE)

## Primary Outcomes

- **Visual Acuity** _(time frame: 3 months)_ — Uncorrected distance visual acuity and uncorrected near visual acuity

## Secondary Outcomes

- **Contrast sensitivity measured by the Functional Acuity Contrast Test (FACT) of the Optec 6500 view-in test system** _(time frame: 3 months)_
- **internal aberration measured by the ray-tracing aberrometer** _(time frame: 3 months)_

## Locations (1)

- Institute of Vision Research, Department of Ophthalmology, Yonsei University College of Medicine, Seoul, South Korea
