Insertion, removal and care

Insertion, removal and care

• Week 11

2
Insertion and removal

• Insertion of gas perm lenses is very similar to
  soft CLs.
• It is imperative to look straight ahead while
  putting the lens on the eye.
• Wherever the lens gets placed, is where it stays.

3
Insertion and removal

• Rigid, gas perm lenses DO NOT center on the eye
  like a soft lens.
• If you look away while placing it on the eye, it
  will need to be recentered.
• Patients must be taught how to recenter the lens.
• While the lens is decentered, it will be very
  uncomfortable. Patients must used very gentle
  pressure so as not to break the lens or scratch
  the cornea.

Insertion and removal

• The removal of a gas perm lens is different than
  removal of a soft CL.
• The CL has to be forced or squeezed out of the
  eye by the lids.
• Gas perm lenses bounce, so your hand or a towel
  should be under the eye to catch the lens.
• There are also suction cups that aid in the
  removal of the lens. One should be very careful
  while using the suction cup not to land on the
  conjunctiva instead of the lens.

5
Insertion and removal

• You are the person responsible for teaching the
  patient how to insert and remove the lenses.
• Make sure you take the time to make sure the
  patient is comfortable and capable of insertion
  and removal and able to relocate the lens if it
  get dislocated.

6
Rigid lens care

• Gas perm lenses have different cleaning systems
  than soft CLs but are equally important.
• Boston is the most commonly used.
• There is a cleaner that removes surface debris
  and disinfects the lens by rubbing directly on
  the lens.
• Lubricant for storing the CL in the case and
  rewetting, if needed.

7
Rigid lens care

• Gas perm lenses are not disposable and can last
  for up to 5 years. Protein from tears can build
  up on the lens and cause the lens to be
  uncomfortable and blurry.
• This can be removed with an enzymatic cleaner
  that is purchased separately.
• The lenses simply soak in the solution or if the
  protein is severe it can be buffed off.
