A cataract is a clouding of human lens inside the eye, resulting in blurred vision. Cataracts generally affect individuals over the age of 50. While cataracts occur as part of the aging process, many other conditions such as trauma, diabetes, vitamin deficiency or inflammatory diseases can accelerate cataract growth. Cataract surgery is a highly successful method of improving vision with the added benefit that many patients can eliminate their need for glasses after surgery. Cataract surgery involves removal of the cloudy lens, and replacement with an artificial lens, which is called an intraocular lens. For decades, these intraocular lenses were of a fixed focus variety, meaning that they would focus on one point in space. Reading glasses were required for near and intermediate vision with these older intraocular lenses. One of Dr. Dell’s primary areas of research is the development of intraocular lenses to eliminate the need for reading glasses. In 2001, Dr. Dell performed a series of operations using special intraocular lenses that could focus both at distance and near. This FDA-sponsored clinical research led to full FDA approval of the first of these lenses in 2003. At Dell Laser Consultants we refer to these special implant lenses as Full Focus® intraocular lenses. Dr. Dell has personally trained hundreds of U.S. surgeons certified to use these advanced Full Focus® implant lenses, and he has lectured around the world on their use. Today, there are several varieties of these advanced intraocular lenses including the Tecnis Multifocal, Symfony, ReStor, Crystalens, Trulign, and others. We now have impant lenses that can correct nearsightedness, farsightedness, and astigmatism. Our doctors will assess the best technology available for your eyes and make a specific recommendation for the best Full Focus® technology to achieve your visual goals.
