management of refractive errors prescription of spectacles

by shukla yogesh

the management of refractive errors and prescription of spectacles depicts refraction and treatment of refractive errors in the field of ophthalmology, particularly to increase the yield of satisfied patients and sharpen the judgment and skills of the superspecialists or ophthalmologist. proper evaluation of refractive errors and spectacle prescription is an integral part of ophthalmic practice. even a patient with early cataract can be very suitably corrected with spectacles and continue his daily work for a long-time. the book possesses clinical points that can aid in finding the refractive error properly and translating it into the best possible pair of glasses. though certain relevant refraction tests and procedures are mentioned or described, the book additionally discusses various types of lenses available in the market, which one to prescribe, suitability of individual patient, and how to prescribe.

irregular astigmatism diagnosis and treatment

by ming wang (editor)
since the advent of keratorefractive surgery and its rising popularity, irregular astigmatism has become an increasingly important issue for ophthalmologists and optometrists. despite the success of lasik and prk, there are more and more patients experiencing visual quality problems due to the non-physiological modification of the corneal structure. among these complications, irregular astigmatism is perhaps the most difficult to treat.

the first of its kind, irregular astigmatism: diagnosis and treatment synthesizes our knowledge and understanding of irregular astigmatism and addresses state-of-the-art technology in management and treatment. dr. ming wang, assisted by dr. tracy swartz, has led a team of internationally known experts in the field to produce this innovative, comprehensive, and logically presented text, which includes more than 300 illustrations to supplement the information provided.

inside you will find:
history and optics of regular and irregular astigmatisms
useful criteria for diagnosis and classification
current state-of-the-art technologies for treatment
suggestions for future direction in treatment technology
every physician who performs keratorefractive surgery understands that in reducing a patient’s refractive error, there is a possibility of creating irreversible effects on visual quality. irregular astigmatism: diagnosis and treatment is intended to help prevent and reduce the iatrogenic creation of irregular astigmatism, as well as provide effective treatment when postoperative complications do arise.

complications discussed include:
decentered treatment
small optical zone
central island
oblate cornea
destablized cornea
in addition, this text systematically separates two distinctly different etiological groups of irregular astigmatism—that of a structurally stable cornea and that of a structurally unstable weak cornea—and comprehensively presents all treatment modalities for each.

treatment technologies addressed include:
uv corneal cross-linking
intacs intracorneal rings
penetrating and lamellar keratoplasties
custom wavefront- and topography-driven treatments
lens surgery and toric iol

with the maturation of keratorefractive technology in recent years, effective treatment for iatrogenic irregular astigmatism is quickly developing. irregular astigmatism: diagnosis and treatment provides everything refractive surgeons, ophthalmologists, and optometrists need to know about this important topic.
