Soft contact lens movement changes over time, initially decreasing then increasing after 8 hours. Early assessment at 5 minutes best predicts long-term lens mobility.

Area of Science:

  • Ophthalmology
  • Biomedical Engineering
  • Corneal Physiology

Background:

  • On-eye hydrogel lens movement is crucial for optimal fit and corneal health.
  • The dynamic changes in soft contact lens mobility over time remain under-investigated.

Purpose of the Study:

  • To characterize the time-course of soft contact lens movement on the eye.
  • To determine the optimal time for assessing lens mobility in clinical settings.

Main Methods:

  • 26 subjects wore hydrogel lenses (38% or 67% water content).
  • Video slitlamp recordings captured lens movement at 5-minute intervals for 30 minutes and after 8 hours.
  • Statistical analysis compared lens mobility based on water content and wearer experience.

Main Results:

  • Lens mobility showed a biphasic pattern: decreasing significantly in the first 25 minutes, then increasing after 8 hours.
  • No significant differences in mobility were found between high/low water content lenses or experienced/neophyte wearers.
  • Lens movement after 8 hours was best predicted at 5 minutes post-insertion (77% accuracy within +/- 0.25 mm).

Conclusions:

  • Soft contact lens movement exhibits significant temporal changes during wear.
  • Assessing lens mobility 5 minutes after insertion provides optimal predictability for 8-hour wear.
  • Clinical assessment at 5 minutes may not fully represent real-world lens mobility in approximately 25% of patients.
