Keratoconus as refractive surgery: Thinking outside the ‘cone’
Keratoconus as refractive surgery: Thinking outside the ‘cone’In this first of a two-part series, Arun C. Gulani, MD, MS, explains how approaching keratoconus as a refractive surgery will change the way both ophthalmologists and patients will approach this condition to bring in a new era of not only relieving but also enhancing the lifestyle of this patient population. In Part 2, Dr. Gulani will share strategies and cases of patients with keratoconus with different case scenarios in action.
How endothelial cell loss in DSEK compares to PKAt the 10-year time point after Descemet stripping endothelial keratoplasty, the endothelial cell density is comparable to that after penetrating keratoplasty at the same time.
Selective two-photon collagen crosslinking: Why more is better
Selective two-photon collagen crosslinking: Why more is betterSelective two-photon collagen crosslinking has been shown to stiffen any three-dimensional region inside corneal tissue without damaging surrounding tissues.
Which is superior: LASIK or contact lenses?Steven Dell, MD, and Steve Schallhorn, MD, compared the visual and subjective outcomes in patients who wear contact lenses with those who underwent wavefront-guided LASIK for the correction of myopia and astigmatism.
Determining best cases for IOL implantation in childrenWhen the topic of IOL implantation is on the table, the age of the patient does make a difference, according to pediatric expert Courtney Kraus, MD, who spoke at the Wilmer Eye Institute’s 27th annual Current Concepts in Ophthalmology conference.
Finding the ideal mix-and-match IOL strategyTwo clinicians explore why an optimal visual solution for patients may be using both a low-add multifocal and an extended-range-of-vision lens.
Why IOL power selection requires ‘different’ thinkingWhile the accuracy of IOL power selection has advanced since the early days of phacoemulsification, the selection of the proper IOL power is always in the background when a surgeon performs cataract surgery, Dr. Hill said.
Genetic, environmental twin studies provide clues to myopiaWith myopia on the rise, greater understanding of genetic and environmental factors is needed to refine interventions that may curtail disease progression.
How myopia shaped the attitudes of Theodore Roosevelt and Ronald Reagan
How myopia shaped the attitudes of Theodore Roosevelt and Ronald ReaganSevere myopia affected the attitudes of both Theodore Roosevelt and Ronald Reagan, but in opposite ways, according to biographer Edmund Morris. “Since both of them became aware of their myopia in their early teens, it was obviously a formative experience for both of them,” Morris told Ophthalmology Times.
Presbyopia therapy: Comparison of corneal versus lens-based optionsThe authors assess the quantitative and qualitative aspects of vision following various lens- and corneal-based therapies for presbyopia. In many cases the KAMRA corneal inlay offers a long-term solution. It can easily be removed if the patient is not satisfied with the outcome.
