Trial to Investigate the Safety and Effectiveness of the KI-362-US1 (YP2.2VM) Intraocular Lens (IOL) in Adult Participants for Correction of Aphakia Following Cataract Extraction

June 10, 2026 updated by: Kowa Research Institute, Inc.

A Prospective, Multicenter, Open-label, Single-arm Clinical Trial to Investigate the Safety and Effectiveness of the KI-362-US1 (YP2.2VM) IOL for Correction of Aphakia Following Cataract Extraction

A study to learn how well an artificial lens, called an intraocular lens (IOL), works in adults who have cataract surgery. During this type of surgery, the eye's natural lens is removed and replaced with an artificial lens to help restore vision.

The main goal of the study is to evaluate vision after the lens is placed in the eye. About one year after surgery, participants' vision will be measured to understand how clearly they can see.

The study will also look at how the lens performs over time, including how well it remains in place in the eye.

The results of this study will help provide more information about how this lens performs in adults undergoing cataract surgery.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Are able and willing to provide written informed consent, attend all scheduled visits, and comply with all trial procedures and follow-up
  • Have a study eye with visually significant cataract for which phacoemulsification cataract extraction and posterior chamber IOL implantation is indicated
  • Meet all other inclusion criteria outlined in the clinical study protocol

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: KI-362-US1
Participants in this study receive an artificial lens (intraocular lens) implanted in the eye to replace the eye's natural lens that has been removed due to cataract surgery. The lens is delivered using a single-use, preloaded device that helps the surgeon place the lens safely and precisely into the natural lens capsule of the eye.
Device: KI-362-US1 (YP2.2VM)
Injector and one-piece (1P) monofocal IOL

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Proportion of Participants whose BCDVA Achieved 0.30 logMAR or Better at Form 5
Time Frame: Baseline (Form 0) through Visit 5 (Form 5), approximately Days 330-390

A binary outcome of achieving best-corrected distance visual acuity (BCDVA) of 0.30 logarithm of the minimum angle of resolution (logMAR) or better, or not, at postoperative days 330-390 (Form 5)

BCDVA will be measured using Early Treatment Diabetic Retinopathy Study (ETDRS) illuminated charts
Baseline (Form 0) through Visit 5 (Form 5), approximately Days 330-390
Proportion of Participants with Incidence of Selected Ocular Adverse Events
Time Frame: Baseline through end of study (up to 15 months)

This safety outcome measure evaluates whether participants experience any of the following ocular adverse events after treatment, recorded as a binary outcome (occurrence: yes/no). Cumulative adverse events assessed include Cystoid macular edema, Hypopyon, Endophthalmitis, lens dislocation from the posterior chamber, Pupillary block, Retinal detachment, and secondary surgical interventions (excluding posterior capsulotomies).

In addition, persistent adverse events are assessed as present or absent, including corneal stroma edema, persistent Cystoid macular edema, Iritis, and elevated intraocular pressure requiring treatment.
Baseline through end of study (up to 15 months)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Proportion of Participants with Lens Axis Misalignment of <10 degrees From Baseline to Form 4
Time Frame: Baseline (Form 0) through Visit 4 (Form 4), approximately Days 120-180
Evaluation of the rotational stability of the implanted monofocal IOL by assessing changes in lens axis alignment over time. Stability is determined using binary outcomes (yes/no) based on whether the absolute difference in lens position between baseline (Form 0) and follow-up visit (Form 4) remains within predefined thresholds.
