The History of Intraocular Lenses
MetadataShow full item record
The striking improvement in lens quality is obvious when comparing intraocular lenses manufactured in the 1970s with those produced in the late 1980s and the 1990s. The current lenses have excellent finish quality and flawlessly engineered configuration of the lens optics. A major part of success in present day intraocular lenses is due to sequestration of the IOL. Current methods of fixation isolate the IOL away from the sensitive tissues of the eye, which virtually eliminates postoperative complications. Since most intraocular lenses currently being used have only been on available for a few years, it is difficult to assess their long term advantages and disadvantages. There is however an estimated success rate approaching 980/0 with the current lenses. Although manufacturers are still striving to design the perfect lens, it will be difficult to improve on this rate of success.
