VIVA

1. Refractive index – definition,
2. Refractive indices of structure in the eye, silicon oil
3. Diffraction - pin hole
4. Snell’s Law 
5. Total internal reflection
6. IOL -three piece, refractive power in air and eye
7. 2.2 pan retinal I/O lens – magnification and back vertex power
8. Lasers

Refraction

1. 15 min for vision, retinoscopy and subjective
2. Asked to do JCC in front of examiners
3. Duochrome in front of examiners
4. Muscle balance for near and distance
5. RE –5.00/0.50@25 LE-5.00@0.25@170
6. BVD - importance and for whom
7. Near vision –Age 60 – be add +2.25 N5 at 40cms
8. Importance of varifocals
9. Focimetry for her glasses – ran out of time

OSCE

1. Left eye with proptosis and dilated episcleral vessels. Was asked to do HERTELS
2. Pupils LE RAPD
3. S/L – corneal guttae and pigments on the endothelium
4. Direct ophthalmoscopy – RE optic atrophy
5. I/O peripheral pigmentation 
6. Cover test – left exotropia with left latent nystagmus
7. Left SO palsy – Parks three step test 
8. Visual fields - peripheral vision with white pin.
