This purpose of this study is to assess the safety and effectiveness of Restasis® ophthalmic
emulsion versus emulsion alone( Refresh Dry Eye therapy) both for the treatment of brittle
nails and for the enhancement of normal nail growth and texture. The investigators think that
daily application of Restasis® to nails and nail beds in patients with brittle nails will
enhance nail growth and improve nail texture in both affected and unaffected nails.
