Patient history
A careful history of the patient is necessary to determine eligibility prior to fitting the patient with EW silicone hydrogel contact lenses. Patients should provide detailed information regarding their past ocular and general health. Motivational factors and compliance with instructions need to be assessed and addressed when the patient history is recorded. EW contra indications include: • diabetes • compromised immune system • conditions that require steroid or other systemic medication • Severe seasonal allergies • Previous reactions to solutions or to hydrogel contact lenses. Caution is advised with patients who have had previous episodes of CLARE or CLPU. The risk of recurrence needs to be taken in account in these cases.
