Table 4 Influence of coma on orientation of refractive astigmatism

From: Assessment of refractive astigmatism and simulated therapeutic refractive surgery strategies in coma-like-aberrations-dominant corneal optics

	Axis of Coma	Axis of DA	TCL + LA	Coma	RA
1	94	98	WTR	Vertical	ATR
2	84	85	WTR	Vertical	ATR
3	97	92	ATR	Vertical	ATR↑
4	93	84	ATR	Vertical	ATR↑
5	119	114	ATR	Vertical	ATR↑
6	84	82	ATR	Vertical	ATR↑
7	51	64	WTR	Oblique	Oblique
8	34	68	WTR	Oblique	Oblique
9	115	81	WTR	Vertical	ATR
10	45	55	Oblique	Oblique	ATR
11	76	106	WTR	Vertical	WTR↓

DA = discrepant astigmatism; TCA = total corneal astigmatism, LA = lenticular astigmatism, RA = refractive astigmatism, WTR = with the rule, ATR = against the rule
↑: increased amplitude of astigmatism
↓: decreased amplitude of astigmatism
