CL wearing scheudle for new patient
◦ Start with 2 hours on first day
◦ Increase by 1-2 hours/day
◦ Maximum of 10 hours/day before follow up
◦ Arrive for follow up with contact lenses in eyes
CL wearing scheudle for experinced patient
◦ Maximum of 14 hours/day
◦ Glasses are necessary for backup and days off
Soft CL care systems
◦ Estimated risk of CL-associated infection is 60 times greater in a CL wearer vs a non-lens wearer
◦ CL prevents clearance of microorganisms from the ocular surface
◦ Risk is significantly increased in wearers who: Don’t regularly disinfect their CLs
Don’t properly use the storage case
Don’t wash their hands
- Hygiene regimen
◦ ‘Rubbing and rinsing’ is more effective in removing microbes than rinsing alone
Removes loosely bound deposits on lenses
Reduces levels of microorganisms on the lenses
The Evolution of Soft Lens Care Systems
◦ Historically, was complex and time-consuming
Heat (1972)
◦ Changed with the introduction of multipurpose solutions (MPS)
Majority of soft CL wearers are prescribed MPS Remaining use peroxide based care system
