Convenience Health Quality Value
Consumer Demand
3
Consumers indicate that a "healthier lens" is the most
important need
4
In their own words, consumers described"healthier" …
What does "health" mean to consumers?
"will not cause infection""better for you, better for your eyes""comfortable, lubricated, safe""optimal perfection, clean and pure""worry free, infection free""healthier body, vision, lifestyle""less strain, less maintenance, less infection""fewer side effects, won't cause problems"
5
Contact Lens that is better than spectacles Contact lens that is free from all complications Contact lens that can be worn in the eye for
longer duration without removal
The Goals of Contact Lens Research
6
Parameter Changes Physiologic compromise leading to tear film disruption and red eye reaction Contact Lens deposits Patient compliance Contamination with Microorganisms
Conventional Contact Lenses
7
Deposits/Films Solution related hypersensitivity Contact lens induced papillary conjunctivitis Old, dirty and contaminated case Compliance
Challenges to successful practice
8
Irritation / reduced comfort
Deposits Complications
• Reduced visual acuity
• Increased potential for infection / inflammation
• Shorten wearing time (CL intolerance)

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

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”.
Frequent Replacement Program (FRP)/Planned Replacement Program (PRP)

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

Disposable Contact Lenses – Patient Selection
Disposable Contact Lenses – Patient Selection
31
• 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
Ideal Candidate for Disposable Lenses

Identifying a suitable PRP lens for your patientIdentifying a suitable PRP lens for your patient
yCounsel your patient on disposable modality
yDetermine wear time: DW/ FW/ EW/ CW schedule
yDetermine replacement schedule
yHow to choose a suitable PRP?
yThickness: For new patients - lens handling is important,
choose slightly thicker lens
yIonicity: Choose between ionic & non-ionic materials,
based on patient’s depositing response
yWater content: Choose between HW & LW based on
patient’s needs
33
y Suggest silicone hydrogels, for patients that complain of
end of the day dryness & discomfort with CLs (eg: Software
professionals, & those working in AC environments)
y Advice to use lubricating eye drops when required
y For glare-free, crisp vision even at night, choose CLs that
correct spherical aberrations (Eg: PureVision from B&L) y Select appropriate vision correction i.e. spherical CL vs.
toric CL
y Affordability

Fitting Disposable & FRP lensesFitting Disposable & FRP lenses
yFitting is similar to other SCL fitting
yFitting procedure much simpler with disposables, because
of Unifit base curves (usually 8.6mm or 8.5mm)
ySimilar patient management
yReinforce compliance with replacement & wear schedule
yEducate on cleaning procedures, avoid neglecting any part
of the procedure
35
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
