If you fit a patient with contact lenses for extended wear you should: 

1. make them aware that extended wear increases their risk of microbial keratitis
2. tell them the signs of possible complications to look out for and what to do in these circumstances
3. ensure they attend for regular contact lens check-ups
4. provide them with an out-of-hours contact number for emergencies, as well as the number of the local eye casualty department.

You must teach the patient how to remove their contact lenses. If the patient has extended wear contact lenses and, because of a disability, is unable to handle them, you must teach their carer how to remove the lenses.¹⁶⁰

The frequency of contact lens check-ups depends upon factors including the patient’s:

1. clinical status
2. history
3. type of contact lens
4. modality of wear.

Because of the increased risk of complications, you should carry out contact lens check-ups for patients wearing lenses on an extended wear basis more frequently than those wearing contact lenses on a daily wear basis.
