PresbyLASIK versus multifocal refractive IOLs
January 1st 2008PresbyLASIK treatment uses the principles of LASIK surgery to create a multifocal corneal surface aimed at reducing near vision spectacle dependence in presbyopic patients. This treatment constitutes the next step in the correction of presbyopia after monovision LASIK.1-3 Among the presbyLASIK techniques, central presbyLASIK 4 creates a central area, which is hyperpositive for near vision leaving the midperipheral cornea for far vision. 5 Positive clinical results of this surgical technique have been recently reported 4 and also tested objectively with a light propagation algorithm. 6
Laser thermokeratoplasty the ideal choice for presbyopes?
January 1st 2008The development of the excimer laser has allowed more and more refractive surgical procedures to be developed, treating ever-expanding indications. As such, LASIK remains the most popular procedure for surgeons seeking to correct myopia. But what about hyperopia, which is traditionally thought to be more difficult to treat?
Acri.LISA Toric 466 TD: a multitalented IOL
January 1st 2008Ophthalmic surgeons have been implanting multifocal lenses for several years, not only in cataract surgery, but also to offset the accommodation lost as a consequence of age. With the newest generation of lenses, more than 80% of refractive and cataract patients can now enjoy life without glasses.
The new generation Crystalens better than the rest?
January 1st 2008The first generation Crystalens accommodating intraocular lens (IOL) (eyeonics) was approved by the FDA in November 2003 and has since undergone two revisions. The first involved modification of the lens optic to a "square" rather than smooth edge in order to reduce the incidence of asymmetric capsular fibrosis, which could cause capsular contraction and IOL tilt
Finding it hard to educate patients about presbyopia-correcting IOLs?
January 1st 2008Presbyopia Correcting IOLs (PCIOLs) are perhaps the most significant technological advancement in recent ophthalmic history. These lenses not only provide patients with the option of seeing near, intermediate, and distant objects without dependence on glasses for most of their daily activities - they could also become the single most important cornerstone for building a successful ophthalmic practice, both now and in the foreseeable future.
