Patient:24 YO Male College Football Player
Condition: Bilateral Keratoconus

Ocular History:
Undetermined manifest refraction due to high corneal irregularity.

Treatment:
Due to high physical activity and poor GP lens tolerance, lens fit was converted to piggy-back system resulting in BCVA 20/50 OU.

Refit in Kerasoft OU with first fit parameters:
• OD BC 8.40, -4.75 -3.75 X 10, Diameter 15.0, Standard peripheral
• OS BC 8.20, -18.25, Diameter 15.0, Standard peripheral

Outcome:
Dispense visit over-refraction:
• OD +1.25 -1.00 X 45 for 20/20 minus
• OS Plano for 20/20 minus

Remade OD with new lens power
-3.75 -4.50 X 65

Shortly following lens dispense, patient was recruited to a professional practice squad, relocated, and neglected follow-up.

Eight months post-dispense

• Patient reaches out to report a drop in visual acuity.
• The patient was instructed to report to the practitioner’s office at their earliest convenience for evaluation.
• Upon evaluation, Kerasoft lenses exhibit excessive movement along with small over-refraction.
• This decline in lens performance is due to lenses being used beyond their effective duty cycle.
• The patient is informed that Kerasoft lenses must be replaced at a recommended 3-month interval.
• The lenses can perform adequately for up to 6 months, but material degradation will result in poor performance beyond that time.
• New Kerasoft lenses were ordered in the original parameters and in multi-packs.
• Original dispense lens performance was restored by the new lenses and the patient was scheduled for routine follow-up.
