Area of Science:

  • Ophthalmology
  • Medical Devices
  • Clinical Trials

Background:

  • Hyperopia, a refractive error, can be treated with intraocular lenses.
  • Phakic intraocular lenses offer a surgical option for vision correction.

Purpose of the Study:

  • To assess the short-term safety and efficacy of the STAAR Surgical Implantable Contact Lens (ICL) for hyperopia treatment.
  • Evaluate the performance of a plate haptic posterior chamber phakic IOL in a U.S. FDA Phase I clinical study.

Main Methods:

  • A prospective U.S. FDA Phase I clinical study involving 10 hyperopic patients (mean +6.63 D).
  • Patients received a single STAAR Surgical ICL in one eye.
  • Follow-up examinations occurred at multiple time points up to 6 months post-surgery.

Main Results:

  • At 6 months, 70% of eyes achieved uncorrected visual acuity of 20/20 or better.
  • 100% of eyes achieved 20/40 or better uncorrected visual acuity.
  • 80% of eyes were within +/-0.50 D of emmetropia, with no reported complications.

Conclusions:

  • The STAAR Surgical ICL demonstrates short-term safety and efficacy in treating hyperopia.
  • The plate haptic posterior chamber phakic IOL is a predictable option for hyperopic correction.
  • Results support the use of this ICL for hyperopia management.
