Patient GF

Male

Age: 27 Years

History: GF had a diagnosis of PMD for around 7 years, the left eye always being worse than the right. He attempted RGP lenses but could not tolerate them and preferred to manage without spectacles at all, as the astigmatism correction in the left eye caused anisometropic symptoms.

Vision	R: 6/6 pt	L: 6/24
Spectacle Rx	R: Plano/-2.00 x 70 VA 6/6	L: -2.00/-6.00 x 110    VA 6/9 with strong ghosting
Keratometry	R: 7.73 x 68/7.30 x 158	L: 7.23 x 111/6.37 x 21

Aberrometry:

Aberrometry shows that the main HOA is coma for both eyes which is the main reason for the visual symptom of ghosting.
