2. • Contact lens wear retention research indicates that 26% of new wearers
cease lens wear within the first year, with nearly half of those dropping
out in first 2 months.
• A deep understanding of the patient’s needs alongside meaningful
clinical evaluations are key to success.
• Determining any contradiction to contact lens wear alongside the initial
clinical assessment will provide you with the information needed to help
recommend the most appropriate lens to the patient.
6. SOFT CONTACT LENS OR RIGID
CONTACT LENS?
• SOFT CONTACT LENS
• Advantages
• Greater initial comfort than hard or RGP lenses.
Shorter adaptation period for new wearers.
Ideal for intermittent wear.
Less susceptible to the intrusion of foreign objects under the lens, such as dust.
Less sensitivity to light than with hard or RGP lenses.
Rarely fall out of the eye, making them ideal for sports, particularly contact sports such
as football or basketball.
Available in tinted versions.
7. • Disadvantages
• Less durable than hard or RGP lenses.
May dry out, causing discomfort for some, especially under a hair dryer, in hot rooms, or
in windy, dry weather.
More involved lens care, especially for conventional soft lenses.
Susceptible to more protein or lipid deposits, that reduces lens performance in the long
term.
May absorb chemicals from the environment, which can cause irritation
8. • RIGID CONTACT LENS
• Advantages
• Clear, crisp vision.
• Correct most corneal astigmatism.
• Good durability.
• Good handling characteristics.
• Easier care system than soft contact lenses.
9. • Disadvantages
• Less initial comfort than soft lenses.
• Longer adaptation period required than soft lenses.
• More easily dislodged.
• More susceptible to the intrusion of foreign objects under the lens, such as dust.
• Can scratch and break.
• Intermittent wear is less feasible because adaptation is required if a person takes an
extended break from use.
