complains of poor vision and reduced comfort. Upon SL eval you find the lenses riding
high under the upper lid.
Possible GPC, deposits on lens, lenses old and loosing it's retention.
A computer operator returns for a F/U visit and complains of blurred vision and lens
awareness.
Lenses drying out
A previous lens wearer notices one lens is more comfortable than the other. Upon
inspection, you find the lens exhibits excessive movement on the up-gaze. The pt's VA
is down in that eye.
Lens inside out
A DW pt's lenses are 1 year old. The pt notices increased lens awareness, red, itchy
eyes and a present discharge.
Lens deposits, possible infection or inflammation such as GPC

Arcus Senilis
A previous RGP pt wants to try soft lenses. With the soft lenses as well as with her
glasses, the pt's VA is down, but she sees well with RGP's. K's:
43.50@175/49.75@045 -> 45.00@180/48.50@075
Spectacle blur and irregular astigmatism
A pt returns for a 2 wk recheck. Using NaF1 and the SL you find staining around the
limbus. Initial K's: 43.50@180/43.75@090 -> 43.75@180/44.00@090. F/U K's:
44.00@180/44.25@090 -> 44.50@180/44.75@090.
Edema from a tight fitting lens
Which series of questions should be asked to gain knowledge about the pt's current
CL?
- How old are the current CL?
- How many hours/day do they wear the CL?
- Do they sleep with the CL?
- Are the CL dry at anytime during the day or end of day?
- Any problems inserting or removing?
- On a scale of 1-10, 10=Great, how comfortable are the CL?
- What solution is being used?
- Any medication changes?
- Do they uses= eyedrops, if yes, why, and what kind?
- How many unopened CL do they have left?
How would you practically perform a pt's VA/OR?
1. Wash hands and clean occluder
2. Instruct pt on where to stand (20 feet) and how to hold occluder.
3. Checked pt's distance VA Binocularly -> Monocularly
4. Perform OR starting with +0.25D binocular -> Monocular. Move on to -0.25D.
5. Checked pt's near VA Binocularly -> Monocularly.
