8.  Irritation / reduced comfort
• Reduced visual acuity
• Shorten wearing time (CL
intolerance)
• Increased potential for
infection / inflammation

obstacles to successful contact lens
wear?

11. Disposable Contact Lenses
“Designed to be thrown away after one use and not
to be laundered or refilled”
(Concise Oxford Dictionary)

12. Frequent Replacement Program (FRP)/
Planned Replacement Program (PRP)
FRP/PRP Lenses
“Intended to be worn &
disinfected, on a daily wear basis and
replaced between 1 month and 3
months”
However some lenses are now
approved for extended wear &
Continuous Wear basis”.

13. Disposables and FRP lenses
Objectives
 Deposit free lens wear
 Optimal wetting properties
 Optimal Ocular health
 Safe wear without many complications
To minimize, if not to eliminate, the need for the soft
contact lenses to be handled and disinfected

23. Classification based on
Wear time
 Daily Wear: - Wear during wake hours;
Requires daily removal & care.
 Extended Wear - Wear up to 7 days/ 6 nights,
(Flexible Wear): without daily removal & care*.
 Continuous Wear: - Wear up to 30 days/ 29 nights,
without daily removal & care*.
*Silicone Hydrogels

26. FDA Classification of Lens Materials
Group Water Content Charge
I Low (< 50%) Non Ionic
II High (> 50%) Non Ionic
III Low Ionic
IV High Ionic
27

27. Protein Uptake of Lens Materials
~ 26x more
deposits than
I, II, & III
28

28. Implications of Lens Material Classification
Ionicity
 Ionic materials have grater tendency to attract deposits
compared to Non-ionic materials
Water Content
 Deposition: LWC deposits less than HWC lenses
 Handling: HWC lenses are more flexible than LWC lenses
 Oxygen flow: HWC transmit more oxygen than LWC
lenses
 Dehydration: HWC has greater dehydration potential
than LWC

29. Disposable Contact Lenses
– Patient Selection
30

30. Ideal Candidate for Disposable Lenses
• Conventional lens wearers
• Frequent protein deposit build up in CLs
• Former CL wearer (*ask reason for drop-out)
• Active lifestyle
• Living in environmentally polluted areas
• Ideal for those who seek convenience
• Business travelers/ part time wearers/ young professionals
• Patients with solution sensitivity
• Patients who want to wear CLs for extended periods
31

31. Identifying a suitable PRP lens for your patient
Counsel your patient on disposable modality
Determine wear time: DW/ FW/ EW/ CW schedule
Determine replacement schedule
How to choose a suitable PRP?
Thickness: For new patients - lens handling is important, choose
slightly thicker lens
Ionicity: Choose between ionic & non-ionic materials, based on
patient’s depositing response
Water content: Choose between HW & LW based on patient’s
needs
32

32. Identifying a suitable PRP lens for your patient
 Suggest silicone hydrogels, for patients that complain of end of
the day dryness & discomfort with CLs (eg: Software professionals,
& those working in AC environments)
 Advice to use lubricating eye drops when required
 For glare-free, crisp vision even at night, choose CLs that correct
spherical aberrations (Eg: PureVision from B&L)
 Select appropriate vision correction i.e. spherical CL vs. toric CL
 Affordability
33

33. Fitting Disposable & FRP lenses
Fitting is similar to other SCL fitting
Fitting procedure much simpler with disposables, because
of Unifit base curves (usually 8.6mm or 8.5mm)
Similar patient management
Reinforce compliance with replacement & wear schedule
Educate on cleaning procedures, avoid neglecting any
part of the procedure

34. Summary
For Healthy Eyes - Choose Disposable/Frequent
replacement Lenses
 Disposable lenses - a fast growing segment
 First choice for new wearers, traditional wearers
 Better choice for healthier CL wear
 Refit choice for patients with complaints of poor
handling, lens tearing & lens dryness
