Vector Analysis Applications to Photorefractive Surgery
TLDR
The methodology in this chapter addresses planning of photoastigmatic refractive surgery as well as the analysis requirements of corneal and refractive astigmatism, andperiodic and frequent analysis of results for ongoing nomogram refinement enables incremental improvement of future treatments and outcomes to be refined.

Astigmatism and the analysis of its surgical correction
TLDR
The nature of astigmatism and its various refractive effects and how this relates to cataract and refractive surgical outcomes is discussed and the use and limitations of vectors and other methods for the analysis of change inAstigmatism after surgery will be discussed along with appropriate statistical methods and suggestions for data presentation.

Vector Planning and Corneal Topographic Astigmatism
The concept of planning refractive laser treatments using parameters other than manifest or wavefront refraction was somewhat of a novelty until topography-guided treatments came to the forefront
Refractive versus corneal changes after photorefracive keratectomy for astigmatism.
TLDR
Success in astigmatism surgery improved, as measured by all parameters, after an additional 20% was applied toAstigmatism treatment magnitude indicated by the VISX computer algorithm.

TLDR
The optimization method described in this article is a consistent reduction in corneal astigmatism towards sphericity, compared to the traditional purely refractive driven treatment, more refractiveAstigmatism will remain in the eye in most cases.

TLDR
Toric ablations with the excimer laser appear to represent a promising strategy for the correction of compound myopic astigmatism that does not rely on creation of deep corneal incisions, excisions, or compression sutures.

ACCEPTANCE OF WEAK CYLINDERS AT PARADOXIC AXES
TLDR
In cases of astigmatism, I refer to instances in which cyclopegia is well effected by homatropine or atropine and in which the question of accommodation does not enter and the sign of the cylinder remains unchanged.
ESTIMATION OF UNCORRECTED VISUAL ACUITY IN MALINGERERS
TLDR
By following the routine about to be described, one may in most cases estimate with reasonable accuracy the uncorrected visual acuity of ametropic persons.
