Abstract

The authors conducted a study to see if fewer surface scratches on rigid gas-permeable contact lenses would occur during cleaning if a cotton swab was used instead of the finger (tip/palm) method recommended by the manufacturers. It was observed that while both techniques resulted in surface scratches, the cotton swab method demonstrated fewer scratches overall. It was found that in every case but one, the manufacturer's recommended cleaning process induced scratches that were both higher in number and severity. It was concluded from our study that longer lens life, better optical clarity and an increased resistance to deposit formation could be long term advantages of cotton swab over finger (tip/palm) cleaning.
