Contact lens check-ups

Sub-sections

Key points

  • When you examine a contact lens wearer you should carry out all the required key assessments, record your findings and communicate them to the patient.
  • You should give the same level of care to patients wearing powered or zero-powered lenses.
  • If you are asked to re-issue or revalidate a patient’s contact lens specification you are responsible for the specification and should check the lenses they are wearing.

Principles of contact lens check-ups

A332
When examining a wearer of contact lenses you must regularly assess the general ocular status of the patient.
A333
If you carry out a contact lens check-up and re-issue the patient’s specification for the same or different contact lenses you are considered to be fitting the patient with contact lenses.93 In this situation you must not fit a patient with contact lenses unless they have an up-to-date spectacle prescription.94
A334
You should give patients wearing powered or zero-powered contact lenses the same degree of care.

Examining contact lens wearers

A335
When you examine a contact lens wearer you should: 
  1. assess the patient’s wearing patterns and wearing times
  2. identify any symptoms they experience while wearing lenses or any signs noted during wear or after lens removal
  3. record the patient’s current care system
  4. measure the refractive status and acuities with the lens on the patient’s eye, including astigmatic elements as appropriate
  5. assess the lens fit and the condition of the lenses themselves
  6. on removal of the lenses, examine the eye and adnexa as required to detect any contact lens related adverse effects. This will include the use of appropriate topical drugs and diagnostic agents
  7. include additional tests which are indicated by the history, risk factors or other information
  8. perform other tests such as keratometry, as required to identify changes from baseline
  9. determine the best spectacle visual acuities following lens removal, if appropriate
  10. assess the patient’s compliance with the care system and general contact lens related hygiene, irrespective of lens type, and
  11. discuss clinical findings and advise the patient of the need for:
    • regular follow-up care, which may have become less obvious over time to existing wearers, and
    • a contact lens assessment before the contact lens specification expires. This is essential to the further supply of contact lenses.
A336
If a patient is considering a new type of lens, you may perform the tests and assessments which are relevant to new wearers. See section on Fitting contact lenses
A337
You should schedule contact lens check-ups according to the patient’s clinical needs. These would normally be every 12 months but may be more or less frequent depending on the type of lens and modality of wear. 

Re-issuing the contact lens specification

A338
A patient might ask you to re-issue or revalidate their specification. In this case, you should tell the patient that you cannot do this unless you know what lenses the patient is wearing. This is because you are responsible for the content of the specification and, therefore, for ensuring that all details on it are correct. Where you have doubts about the specification of the current lenses the patient is wearing, you may need to re-fit the patient.

Routine eye examination

A339
You should remember that there is an ongoing responsibility for the total optometric care of the patient and this would include periodic eye examinations. Where the eye examination is not combined with the contact lens check-up you should explain this to the patient and tell them when a full examination is required.
