Like clothes, lenses need cleaning on removal not before wearing. GP storage solutions, in particular, contain wetting agents, which should not be washed off.
Tap water is to be avoided as, the chlorine and mineral content can react with the preservatives contained in soaking solutions, some times causing whitish particulate deposition.
Scratches can be caused by small particles or even lint from towels remaining on palm and fingers.
Storage Case Hygiene
The easiest patient non-compliance behavior is resistance to changing a dirty case. Over 70% of cases are contaminated from overuse and 23% (nearlt 1 in 4) of all contact lens wearers never replace their lens cases. The storage case, which is handled after washing hands, prior to lens wear. If not maintained clean, is a source which tends to create lens wear problems. Frequent cleaning or replacement of the storage container is an inexpensive way of ensuring scratch and contamination free lenses.
All the items referred to are small in themselves, however !!!
A reasonable amount of time needs to be spent with the patient explaining these MINOR POINTS in order to AVOID MAJOR PROBLEMS later.
One more item needs to be addressed and that is of new lenses being ordered to the old specifications of lenses the patient has been wearing. This inevitably leads to problems. Copying old lenses may look like a convenient short cut but in the long run it is better to have the patient come to you after about 3 to 4 days without wearing lenses for an evaluation of the fit before ordering a new lens or a pair.
The trial lens fits well – The prescription lens does not.
More often than not the trial set lenses are mixed up. The trial lens, which fits well, is stored in the container carrying the label of a different lens. This can easily happen if 2/3 nlenses are taken out of the Trial Set for trials and then returned to the trial set mailer or vial.
