Practical Astigmatism. Planning and Analysis

The surgical correction of astigmatism is the last frontier to optimizing visual outcomes for patients. Practical Astigmatism: Planning and Analysis is a comprehensive guide to correcting astigmatism from pre-operative planning to post-operative analysis. This provides readers with unique insight to what actually happened surgically: did the astigmatism over or under correct? Was it on-axis or off-axis? With this book, ophthalmologists will be able to analyze previous procedures with the appropriate nomograms and more often achieve targeted outcomes.

Dr. Noel Alpins has developed the Alpins Method of astigmatism to provide accurate planning and analysis of astigmatism procedures. His method focuses on analyzing refractive and corneal astigmatism parameters and using the results in future surgery to improve visual outcomes. The importance of the ocular residual astigmatism (ORA) is detailed when planning astigmatism surgery.

Practical Astigmatism features vector planning for refractive laser surgery as well as planning and analysis applied to cataract and limbal relaxing incisions, in addition to demonstrating graphical analysis of astigmatism using high quality vector and fan diagrams, as used in scientific journals. In addition, hemidivisional analysis of the irregular cornea, corneal coupling in incisional and excimer laser surgery for mixed astigmatism and toric IOL planning with total corneal power using corneal topographic astigmatism (CorT total) are addressed as well.

Reviews

"For more than two decades, Noel Alpins has been one of our foremost authorities in the implementation and analysis of astigmatism treatment. Now, Noel has organized his many significant contributions into a single comprehensive textbook - a practical road map to navigate our current clinical options". - David F. Chang MD

"For more than three decades I have been listening to, arguing with, and admiring the work of Dr. Noel Alpins in the field of astigmatism". - Robert H. Osher, MD

"Noel is an original thinker who took on and conquered the complexities of astigmatism analysis, publishing the seminal papers on the way". - Dan Z. Reinstein, MD, MA (Cantab), FRCSC, DABO, FRCOphth, FEBO
