Treating Patients in Los Angeles & Orange County
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.
Another 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 IOL Procedure
The 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 IOL, or intraocular lens (IOL) implant, which is permanently affixed to the eye.
History of IOL
The first IOL 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.
CATALYS LASER ASSISTED CATARACT SUGERY
For patients in need of cataract surgery, the Los Angeles-based laser eye surgeons of Laser Eye Center proudly offer the Catalys precision laser system. This cutting edge technology allows for laser assisted cataract surgery that includes liquid optics with an integral guidance system for the surgeon. Older techniques involve using an ultrasonic hand-held machine with a steel tip to break apart the cataract-affected lens in the eye.
The Catalys also uses a proprietary 3D imaging system to map the surface of the eye, allowing the surgeon to customize treatment for the patient. As such, the femtosecond laser pulses are delivered to the eye with extraordinary precision. This system also provides a gentle dock for the patient, minimizing rise in eye pressure during the surgery and lessening ocular redness after the surgery.
Laser assisted cataract surgery provides a predictable, noninvasive technique to an age old problem. The advanced features of the Catalys system allows our surgeons to deliver quality results, time and time again.
