CASE REPORT
A fifty-eight year old presented for re-evaluation of multifocal contact lenses. She had
been previously successfully wearing translating bitoric multifocal GP lenses. As an
anesthesiologist, these lenses were causing decreased comfort, intermittent dryness
and intermittent blur due to her very specific visual tasks.
Multifocal soft toric lenses were attempted without success.
She currently wears her progressive addition lenses for work but finds these may also
cause blur depending on the operating room set up.
Her past ocular history was unremarkable for other eye conditions. No previous injury
or significant ocular or systemic disease in either eye. All ocular findings were unremarkable
including dilated fundus exam. |

PLAN
Custom Stable Aurora multifocal lenses were recommended as an evolutionary step, to
address her task specific focal distances, symptoms of dryness and increase stability of
her visual correction.
Lenses were selected based on diagnostic fit from a Custom Stable Elite 14.8 fitting set
and over-refraction. |
