Vector Analysis Applications to Photorefractive Surgery
- MedicineInternational ophthalmology clinics
- 2003
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
- MedicineThe British journal of ophthalmology
- 2002
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

Combining refractive and topographic data in corneal refractive surgery for astigmatism: a new method based on polar value analysis and mathematical optimization.
- Physics, MedicineActa ophthalmologica

ACCEPTANCE OF WEAK CYLINDERS AT PARADOXIC AXES

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.
