myopic LASIK and PRK

Vector planning delivers superior outcomes for myopic astigmatismExcimer laser treatments using vector planning resulted in less corneal astigmatism, less refractive cylinder, and better unaided visual acuity postoperatively than treatments using manifest refractive treatment parameters alone, according to Noel Alpins, MD.
New approach to corneal power estimation in eyes with previous corneal refractive surgery and keratoconus eyesThe use of a keratometric index to estimate total corneal power calculation is imprecise, especially in corneas with keratoconus or after myopic laser refractive surgery. The errors can be reduced by using an adjusted keratometric index, consisting of a variable keratometric index that depends on the radius of the anterior corneal surface.
Presbyopia compensation with femtosecond laserThis article discusses the advantages and limitations for surgical compensation of presbyopia with the femtosecond laser using corneal inlays and the Intracor technique.
Anterior segment OCT helps define variations in epithelial thickeningAnterior-segment optical coherence tomography was used to characterize changes in the corneal epithelial thickness patterns after myopic LASIK and PRK.
