• Exam findings:
– Cornea OD – fleisher’s ring 1+ straie, no scarring
– Cornea OS – clear
– All other findings WNL
• Humphery atlas ordered.
• Keratoconus Dx, OD>>OS – see topography
• Fit last year with Synergeyes A lens, good
correction OD only.
• Final lens: Synergeyes A/ 7.1 (8.4 skirt)/ 2.75/14.5 ---20/25

annual medical exam
Humphery topography 7/2009

• No problems with vision, good comfort of
lens, vision seems stable.
• 20/30 OD (thru hybrid lens)
• 20/25 OS (uncorrected)
• Cornea OD
– 1+ punctate staining central inferior, no scarring
– All other findings WNL
• Plan: Refit OD with steeper BC/different lens
design
•
•
Initial Dx lens: Clearkone 250 vault/-4.50/14.5/ medium skirt
Clearance central and light feather touch in ILZ, good movement
• +3.50 Over-refraction of diagnostic lens =
20/30 vision
• Likely may improve when SPK/PEE resolves
• RTC 2 weeks for contact lens/cornea check
• Decreased Vault: ClearKone 200 vault/-3.00/14.5/ medium skirt,
• Good movement (0.25 MOB) but too much touch central and in ILZ
