Bonus questions:
1. The keratometry reading of a myopic eye of 5 Diopters is 43 Diopters and 41 Diopters horizontally and vertically respectively. What is the expected average k-reading after refractive surgery in general?
a) 38
b) 40
c) 41
d) 45
Ans: 38D
a) 38
b) 40
c) 41
d) 45
Ans: 38D
(Hint: Predicted avg k = avg pre-op k - 80% of Ref error)
Mind that if it is hyperopia of 5D, predicted avg k = 47D, because Post-op k = avg pre-op k + 100% of Ref Error)
2. The typical irregular against-the-rule astigmatism in which the topographic steepening nasally and temporally connects inferiorly is seen in
2. The typical irregular against-the-rule astigmatism in which the topographic steepening nasally and temporally connects inferiorly is seen in
a) Keratoconus
b) Post-pk
c) PMD
d) Keratoglobus
Ans: Pellucid Marginal Degeneration (PMD), the topographic impression is also called kissing pigeon appearance, as it resembles the beaks of pigeon joined at the center.
