Outcome Measures

Primary Outcomes (2)

  • Elevated Intraocular Pressure (IOP) in Primary Eyes ≥ 30 mmHg

    The number of primary (first implanted) eyes that have elevated intraocular pressure measuring ≥ 30 mmHg as assessed with applanation tonometry which is a noninvasive test that measures the pressure inside the eye by flattening a part of the cornea.

    1-6 hours postoperatively

  • Elevated Intraocular Pressure (IOP) in Primary Eyes ≥ 40 mmHG

    The number of primary (first implanted) eyes that have elevated intraocular pressure measuring ≥ 40 mmHG as assessed with applanation tonometry which is a noninvasive test that measures the pressure inside the eye by flattening a part of the cornea.

    1-6 hours postoperatively

Secondary Outcomes (2)

  • Elevated Intraocular Pressure (IOP) in Fellow Eyes ≥ 30 mmHg

    1-6 hours postoperatively

  • Elevated Intraocular Pressure (IOP) in Fellow Eyes ≥ 40 mmHG

    1-6 hours postoperatively

Other Outcomes (8)

  • Cumulative Rates of Increased Intraocular Pressure (IOP) in All Eyes Attributed to Retained OVD

    1-6 hours postoperatively

  • Cumulative Rates in Increased Intraocular Pressure (IOP) in All Eyes Attributed to Other Causes

    1-6 hours postoperatively

  • Cumulative Rates of Increased Intraocular Pressure (IOP) in All Eyes Attributed to Retained OVD

Study Arms (1)

EVO ICL

OTHER

STAAR EVO implantable collamer lens (ICL) for the correction or reduction of myopia or myopia with astigmatism.

Device: EVO ICL

Interventions

EVO ICLDEVICE

The EVO ICL is intended to be implanted within the posterior chamber, directly behind the iris, and in front of the anterior capsule of the human crystalline lens.

EVO ICL

Eligibility Criteria

Age21 Years - 45 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Moderate to high myopia correctable with available EVO ICL powers.
  • Moderate to high myopic with astigmatism correctable with available EVO ICL powers.
  • Stable refractive history within 0.50 D cylinder for 1 year prior to implantation.
  • Stable refractive history within 0.50 D for spherical equivalent 1 year prior to implantation.
  • Able and willing to return for scheduled follow-up examinations after surgery.
  • Able to read, understand and provide written informed consent on the Institutional Review Board (IRB) approved informed consent form (ICF) and provide authorization as appropriate for local privacy regulations.

You may not qualify if:

  • Ocular hypertension or glaucoma.
  • Insulin dependent diabetes or diabetic retinopathy.
  • History of previous ocular surgery.
  • Monocular.
  • Pregnant or nursing women, or those who plan to become pregnant over the course of this clinical study or has another condition with associated fluctuation of hormones that could lead to refractive changes.
