Orthokeratology uses special rigid contact lenses to temporarily correct myopia and astigmatism. This method

Area of Science:

  • Ophthalmology
  • Optometry
  • Corneal Reshaping

Background:

  • Orthokeratology offers a non-surgical approach to vision correction.
  • Rigid gas permeable lenses with specific designs are key to this process.

Purpose of the Study:

  • To describe the essential features of tetra-curve reverse geometry back surface design rigid contact lenses used in orthokeratology.
  • To list favorable and unfavorable clinical characteristics for orthokeratology.
  • To highlight the role of videokeratoscopy in assessing corneal health during orthokeratology.

Main Methods:

  • Description of tetra-curve reverse geometry back surface design rigid contact lenses.
  • Empirical fitting or diagnostic lens fitting of reverse geometry lenses.
  • Utilization of videokeratoscopy for evaluating corneal distortion.

Main Results:

  • Tetra-curve reverse geometry lenses are designed for myopia and astigmatism reduction.
  • Specific patient and lens characteristics influence orthokeratology success.
  • Videokeratoscopy aids in identifying issues like poor lens centration and resultant corneal distortion.

Conclusions:

  • Rigid lenses with reverse geometry designs are effective in orthokeratology.
  • Understanding lens design and patient factors is crucial for successful outcomes.
  • Videokeratoscopy is a valuable tool for monitoring corneal adaptation and ensuring optimal lens fit.
