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

Irritation / reduced comfort

Deposits Complications

• Reduced visual acuity

• Increased potential for infection / inflammation

• Shorten wearing time (CL intolerance)

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

34

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
