Area of Science:

  • Ophthalmology
  • Optometry
  • Corneal Physiology

Background:

  • Extended wear contact lenses provide continuous vision correction.
  • Rigid gas permeable (RGP) lenses are an alternative to soft lenses for extended wear.
  • Understanding RGP extended wear is crucial for patient eye health.

Purpose of the Study:

  • To review the literature on rigid gas permeable (RGP) extended wear contact lenses.
  • To discuss the benefits and adverse reactions associated with RGP extended wear.
  • To provide guidelines for successful RGP lens wear and complication prevention.

Main Methods:

  • Systematic literature review of studies on RGP extended wear contact lenses.
  • Analysis of reported benefits and adverse reactions.

  • Synthesis of findings to establish success parameters and prevention guidelines.

    • Main Results:

    • RGP extended wear offers specific advantages for certain patient groups.
    • Potential adverse reactions include microbial keratitis, hypoxia, and inflammatory conditions.
    • Successful wear is associated with appropriate lens design, fitting, and patient adherence.

    Conclusions:

    • Rigid gas permeable (RGP) extended wear is a viable option when managed correctly.
    • Adherence to proposed parameters and guidelines can minimize risks.
    • Further research may refine optimal protocols for RGP extended wear.
