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
AnswerQ: 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
OSPE: 6Optics: Retinoscopy
Retinoscopic findingQuestiona) Convert them into spectacle forms with minus cylinder notation (assuming that you performed the retinoscopy at a workingdistance 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 achieveda working distance of 50cm from the patient)
AnswerThe 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 90Answerb. 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 180OSPE:7Glaucoma: Optic disc
