Astigmatism, toric lens, corneal curvature, contact lens - A State of Sight #7

Isaac Porter, MD explains that astigmatism is an uneven curvature of the eye that can be corrected with glasses, contact lenses, LASIK, or cataract surgery with toric lens implants. Astigmatism is very common and many patients do not understand what it is. In this episode of A State of Sight, astigmatism is clearly defined in an understandable way.

LASIK vs. PRK, laser vision correction, LASEK, epi-LASIK - A State of Sight #6

Isaac Porter, MD explains the differences between LASIK and PRK and the advantages of each procedure in A State of Sight. Many patients will have a choice between LASIK and PRK when they decide to have laser vision correction. In this episode, Dr. Porter outlines the differences that can help patients decide between the two procedures. Some patients with thin corneas may not qualify for LASIK, so their only option is PRK. Others with outer layer corneal haze (anterior basement membrane dystrophy) may benefit more from PRK than LASIK. LASIK may be preferred in patients that are very nearsighted to reduce the risk of haze after surgery.
