CL Comfort. - C-116117 ABDO 1-7-2026
- Contact lens discomfort (CLD): the patient has no signs of dry eye but has discomfort with contact lenses, which ceases once the lenses are removed (23%)
- Contact lens associated dry eye (CLADE): the patient has signs of dry eye but only has symptoms while a contact lens is worn
- Contact lens induced dry eye (CLIDE): the patient has signs of dry eye but did not have symptoms until they started to wear contact lenses and their symptoms now persist even after the lens is removed
- Dry eye disease (DED): the patient had signs and symptoms of dry eye before they started contact lens wear, and these signs and symptoms persist even when no lenses are worn
Key takeaways
- Correlation of lens awareness and perceived reduced clarity of vision
- There is no end of day benefit when:
- lenses are replaced during the day
- lenses are removed, soaked in saline and reinserted
- lenses are moved to the conjunctiva and recentred
- There is a small benefit by instilling drops or saline (no difference in benefit)
- 51% cite discomfort for discontinuation of CL wear
- Correlation between MGD and CL discontinuation
- Myopes may struggle with NV
- may routinely remove specs to read
- spec lenses create base in prism to aid convergence
- with CL wear Px are always looking through the optical centres
- Especialy with early presbyopes, this can become syptomatic wear
- Dk/t has no correlation with comfort.
- silicone may take up to 20 minutes for optimal comfort
- Low modulus lenses may be more comfortable (studies vary)
- In primary gaze, the tighter the fit the better the comfort
- Friction with lid wiper epitheliopathy affects comfort
- Lens wettability is important for comfort
