IOL implantation

Performing cataract surgery with phaco in patients with previous implantationsThis case study presents the results and advantages of phacoemulsification, which Dr Dieter W Klass and his team applied after previous implantation of an iris-fixated phakic IOL (pIOL) (Artisan, Ophtec) for the correction of high myopia without explantation of the pIOL.
Increasing IOL power prediction accuracyIn a multicenter trial including 162 eyes undergoing cataract surgery with implantation of a variety of IOL types, use of intraoperative aberrometry to guide IOL spherical power selection minimized residual refractive error.
Glaucoma risk may increase after cataract removal in early infancy
Glaucoma risk may increase after cataract removal in early infancyGlaucoma is more likely to develop in children who undergo cataract surgery when they are 6 weeks or younger.
Tool allows cataract extraction, IOL implantation, silicone oil removal in one-stage procedureA new instrument can be used during cataract surgery to remove silicone oil placed in the vitreous cavity during prior surgery for complicated retinal detachment.
IOL centration stable 30 days after implantation, study confirmsOphthalmologists spend significant amounts of time during cataract surgery trying to precisely center an implanted IOL to achieve the best possible vision after surgery. The high success rate of cataract surgery suggests that in most cases, they succeed.
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.
Comparing laser-assisted vs. conventional refractive cataract surgery
Comparing laser-assisted vs. conventional refractive cataract surgeryCataract surgery is one of the most commonly performed medical procedures and the leading diagnosis for outpatient surgery visits (3 million) in the U.S. In the past decade, the introductions of presbyopic and toric intraocular lenses (IOLs) have elevated cataract surgery into a refractive procedure. The latest introduction of femtosecond laser-assisted cataract surgery may further improve the predictability and safety of refractive cataract surgery and enhance refractive outcomes.
The pros and cons of clear lens exchangeMore and more well-informed individuals are requesting lens extraction for refractive purposes even though their natural lenses are clear.
Abbot receives CE Mark for Tecnis Symfony extended range of vision IOLAbbott recently announced it has received CE Marking (Conformité Européenne) in Europe for the Tecnis Symfony extended range of vision intraocular lens (IOL) for the treatment of cataract patients who may also have presbyopia.
Visualization, guidance goes 3DThree-dimensional (3D) visualization and guidance may be the future of lens IOL implantation. Douglas Koch, MD, posed two questions: Can surgeons eliminate marking for toric IOLs and eliminate the oculars on the microscope as well?
