Optics: Contact lens
Page 21
Question
An aphakic patient who wears 8.6/13.5/+10.00 soft contact lenses consulted you for a pair of back up glasses.
Q: 1) What do the numbers mean?
8.6________________________
13.5________________________
10.00 ________________________
Q: 2) What is the spectacle power required if the vertex distance is 10 mm?
Q:3) What problems can occur with aphakic spectacle? Mention 4
Page 22
Answer
Q: 1)
8.6 = base curve. 13.5 = diameter . 10.00 = lens power
Q: 2) 9.09 D
Q: 3) Any 4
Ring scotoma .
Pincushion effect.
excessive magnification.
altered depth perception.
weight of the glasses
Page 23
OSPE: 6
Optics: Retinoscopy
Page 24
Retinoscopic finding
Page 25
Question
• a) Convert them into spectacle forms with minus cylinder
notation (assuming that you performed the retinoscopy at a
working distance of 67 cm from the patient).
• b) Convert them into spectacle forms with positive cylinder
notation (assuming that your consultant had an elbow injury
and can only achieved a working distance of 50cm from the
patient)
Page 26
Answer
a. The power crosses translate to spherocylindrical corrections
(with minus cylinder) of
RE +1.50 / - 4.00 X 135
LE -0.75 / -1.25 X 90
As the working distance is 2/3 meter, -1.50 D is subtracted from the above
giving
RE PL / -4.00 X 135
LE -2.25 / -1.25 X 90
Page 27
Answer
b. The power crosses translate to spherocylindrical corrections
(with positive cylinder) of
RE -2.50 / +4.00 X 45
LE -2.00 / +1.25 X 180
As the working distance is now 1/2 meter, -2.00D is subtracted from the
above
RE -4.50 / +4.00 X 45
LE -4.00 / +1.25 X 180
