2. 1.Poor maintenance
- lens should be cleaned & disinfect after use
- clean the casing
- wash hands before touch CL
2.Over-extended wear
- wear more than 14 hours

3. 3.Wearing contact lens in polluted
environment
- Dust, smoke can contribute to lens
contamination
3.Incomplete blinking
- can cause contact lens drying because reduction
of tear exchange between lens and cornea
- recommended blinking exercise
4.Use of drugs
- antihistamine, diuretics reduce tear production

4. 3.Smoking
- Lipid layer of tear film deteriorates due to
smoking
4.Wear contact lens without professional
control
- Especially those who buy through internet. No
aftercare

5. COMMON
SYMPTOMS
Pain Reduce in VA
Conjunctival
hyperemia
CL intolerance

6. LID
oBLEPHRITIS
oCHALAZION

7. CORNEA
 SUPERFICIAL PUNCTATE
KERATITIS
 CORNEAL EDEMA
 NEOVASCULARIZATION

9. CONJUCTIVA
GIANT PAPILLARY
CONJUNCTIVITIS
RED EYE

10. PREVENTION
a)Correct selection of CL candidate
- practice good hygiene
- look at the occupation of the CL
wearer ( determine if the patient is
exposed to chemicals or dusty
environment)
- whether the candidate is responsible
or not

11. b)Accurate selection of contact lenses
c)Give complete education on CL:
: care
: handling
: wearing hours
d)Patient is able to come for aftercare
e)Plan for contact lens change

12. CASE STUDY
SUBJECTIVE:
o A 32 year-old woman
o Good general health
o Takes birth control pills
o Worn disposable extended-wear soft lenses
for 2 years on a continuous 7-day-wear
regimen. Lenses are removed after 1 week,
with one night sleep without lenses
o She disinfects her lenses and uses them
again for a second week before discarding.

13. Objective:
RE LE
VA 6/6 6/6
SLIT LAMP Grade 2 bulbar redness
Grade 2 epithelial microcysts with
mild staining
Assessment:
Grade 2 epithelial microcysts secondary to
long-term extended wear

14. Plan:
1.Discontinue extended wear. Revert to daily
wear.
2.Continue use of disposable lenses, with lens
replacement at 2-week intervals.
3.Follow-up in 6 weeks; monitor number of
microcysts.
