Summary

A new soft contact lens, the Soft K, offers improved comfort and vision for keratoconus patients intolerant to rigid gas-permeable lenses. This design is particularly beneficial for athletes and those with mild to moderate irregular corneas.

Area of Science:

  • Ophthalmology
  • Optometry
  • Biomedical Engineering

Background:

  • Contact lenses have been used for refractive correction since the 19th century.
  • Keratoconus management often involves rigid gas-permeable (RGP) lenses.
  • Intolerance or fitting issues with RGP lenses necessitate alternative solutions.

Observation:

  • A new soft contact lens, the Soft K, features a thick, fenestrated design.
  • It is intended for patients with mild to moderate corneal distortion and RGP lens intolerance.
  • Case reports involved fitting three eyes of two patients with mild keratoconus.

Findings:

  • Patients reported significant improvements in comfort and vision quality compared to previous RGP or soft toric lenses.
  • The Soft K lens provided stable correction and a full field-of-view, crucial for athletes.

  • No physiological complications like edema or neovascularization were observed during follow-up.

    • Implications:

    • The Soft K lens is a viable alternative for patients intolerant to RGP lenses.
    • It addresses the needs of individuals in dynamic activities, such as sports.
    • This soft lens design offers a promising option for managing mild to moderate keratoconus with irregular astigmatism.
