Clinical evidence for Class III ophthalmic implants, that survives Article 61.

IOLs, MIGS and retinal implants that once enjoyed easy access now face intense scrutiny. Historical literature is no longer defensible. Here is the evidence strategy that holds up.

The paradigm shift

Why ophthalmic evidence just got harder.

Devices that once enjoyed straightforward access — intraocular lenses (IOLs), minimally invasive glaucoma surgery (MIGS) devices — now face intense clinical scrutiny under the strict framework of MDCG 2020-6. Sufficient clinical evidence is no longer just a regulatory hurdle; it is the determinant of commercial viability. Relying solely on historical literature is no longer defensible.

The four pillars of Class III ophthalmic evidence.

01

Article 61 investigation

A pre-market clinical investigation is strictly mandatory for novel Class III ophthalmic implants, designed and executed entirely in accordance with ISO 14155.

02

The equivalence barrier

Claiming equivalence for a Class III device now requires a legal contract ensuring ongoing access to the technical documentation of the presumed equivalent device.

03

Objective endpoint capture

Ophthalmic trials demand specialised capture: OCT imaging, strict IOP measurement protocols, and specular microscopy for endothelial cell counts.

04

Continuous PMCF

A CE mark is only the beginning. Long-term PMCF through registries or prospective observational cohorts is mandatory.

By device category

Notified Bodies scrutinise by mechanism of action.

01 / 03

Intraocular lenses (IOLs)

Refractive and cataract IOLs are judged on visual acuity outcomes, refractive predictability, and safety endpoints including endothelial cell loss measured by specular microscopy. A prospective investigation with adequate follow-up is the expectation for novel designs.

02 / 03

MIGS & glaucoma devices

Glaucoma devices hinge on IOP reduction, sustained over time and captured under strict measurement protocols, alongside medication burden and safety. The benefit must be demonstrated, not assumed from mechanism.

03 / 03

Retinal & high-risk implants

Novel retinal implants sit at the top of the risk ladder: a mandatory Article 61 investigation, objective imaging endpoints, and a PMCF architecture designed before the CE mark, not after.

The through-line

  • Objective, instrument-based endpoints over subjective assessment
  • Equivalence only with a contractual right to the predicate’s technical file
  • PMCF designed into the strategy from day one

Questions we hear first

Class III ophthalmic evidence, answered.

Do Class III ophthalmic implants need a pre-market clinical investigation?
Yes. Under EU MDR Article 61, a pre-market clinical investigation is strictly mandatory for novel Class III ophthalmic implants such as many intraocular lenses, retinal implants and glaucoma devices. It must be designed and executed in accordance with ISO 14155, and historical literature alone is no longer a defensible path.
Can I still use equivalence for a Class III ophthalmic device?
Claiming equivalence for a Class III device now requires a legal contract ensuring ongoing access to the full technical documentation of the presumed equivalent device. Without that access, equivalence cannot be substantiated, which is why most novel Class III ophthalmic implants need their own clinical investigation.
What endpoints do ophthalmic trials require?
Ophthalmic trials demand specialised, objective data capture, including OCT imaging, strict intraocular pressure (IOP) measurement protocols, and specular microscopy for endothelial cell counts. Objective endpoints are what let a Notified Body accept the clinical evidence for high-risk ophthalmic devices.
Is PMCF mandatory after CE marking for ophthalmic devices?
Yes. The CE mark is only the beginning. Long-term Post-Market Clinical Follow-up through registries or prospective observational cohorts is mandatory for Class III ophthalmic devices, confirming long-term safety and performance across the device's lifetime.
