Crystalens for Cataract & Reading Vision

Reading Vision after Forties

Presbyopia is a common condition that can affect people as early as their forties. As one ages, the eye loses flexibility and experiences difficulty focusing through a range of distances. With this condition people struggle with close range vision, also known as farsightedness and can no longer read without eyeglasses.

Cataracts

Cataract Removal Laser SurgeryAnother common age-related eye problem affecting millions is cataracts. Cataracts resulting in a clouding of the eye’s lens, called the crystalline lens, impair not only the flexibility of the eye, making it impossible to focus properly, but also produce a clouded vision at all focal ranges. The once transparent lens becomes opaque, as though covered by a gauze curtain, preventing the proper amount of light to enter the eye. Initial symptoms include a glare coming from light sources at night and a pronounced reduction of visual clarity in low-light situations.

The IOC Procedure

Cataract Removal Laser SurgeryThe procedure used to remove cataracts has become quick and straightforward with today’s technologically advanced equipment. The process takes less than half an hour, is painless with the use of local anesthesia, and has a very high rate of success with few, if any, complications. A small incision is made to facilitate lens removal. Once the natural lens is removed, normally through a process called extracapsular cataract extraction (ECCE), the clouded lens is discarded, leaving most of the lens capsule in place. Once the natural lens is taken out, a new transparent, synthetic lens replaces it. This process is called an IOC, or intraocular lens (IOL) implant, which is permanently affixed to the eye.

History of IOC

The first IOC was performed in 1960 by a Russian ophthalmologist named Svyatoslav Nikolayevich Fyodorov, who was credited with discovering the cure for cataracts. He was also recognized for developing a new technique for curing early-stage glaucoma and for his widely known technique used for curing myopia by reshaping the eye’s cornea, a procedure called Radial Keratotomy.

The Crystalens Technology

From those beginnings in 1960, cataract surgical techniques have advanced greatly, especially in the design and function of the synthetic lenses now being implanted. Gaining FDA approval in 2003, the Crystalens is now the preferred intraocular lens (IOL) used in the treatment of cataracts and presbyopia. In contrast to the older static-type lenses, the Crystalens has the ability to move with the muscles of the eyes, improving not only clarity of sight but also focus in all ranges of vision — near, far and everything in between. Most patients also experience an enhanced vibrancy of colors in their environment.
