Patients with cataracts have several options for cataract surgery, and now many eye surgeons are sing an innovative procedure using the Crystalens technology. Crystalens is one of the greatest advancements in intraocular technology and vision enhancement in recent years, and is an implantable lens that focuses just like the eye’s natural lens so that the patient can see clearly up close, far away and all the distances in between. In most cases, the doctor is able to restore the patient’s vision to 20/20 or better, which means they can eliminate the need for glasses or contacts altogether.
About Cataract Surgery
Cataract surgery typically involves the complete removal of the existing lens and replacing it with an artificial clear lens, called an intraocular lens (IOL). The procedure is performed within minutes using a microsurgery technique, and typically requires a tiny incision in the eye that is no larger than 3 mm in length.
Cataract surgery is necessary when the cloudiness that develops inside the eye causes a decrease in vision. Cataracts are a result of steady deterioration of the protein structure within the lens of the eye over time, and some of the symptoms include sensitivity to light, decreased night vision, hazy or cloudy vision, and deterioration of long or short vision. The risk of cataracts increases as an individual gets older, and some of the risk factors include smoking and alcohol use, diabetes, and prolonged exposure to sunlight. When deteriorating vision interferes with day-to-day activities, an eye surgeon must perform cataract surgery using the appropriate intraocular lens.
How Crystalens for Cataracts Works
The Crystalens is a single-focus lens made with a specially-formulated solid silicone compound called Biosil. What makes Crystalens different from traditional intraocular lenses is that it engages the muscles of the eye to move and focus on objects at any distance, and can be customized to different strengths depending on the level of vision correction the patient needs.
The Crystalens procedure is performed using a similar technique as traditional cataract surgery, but the procedure is much less painful and can be performed in approximately twenty minutes. The surgeon uses eye drops to numb the eye and removes the damaged lens using a very small incision. The Crystalens is placed over the area where the damaged lens used to be, and there are no stitches required because the healing process starts shortly after placement.
The Crystalens procedure is suitable for anyone with cataracts, but those who have uncontrolled diabetes or chronic infections are not good candidates for any type of cataract surgery. Patients who have undergone other types of surgeries of the eyes can undergo lens replacement.
If a doctor or optometrist suspects that you have a cataract, they will refer you to an eye surgeon for a comprehensive vision assessment. The assessment will include a measurement of eye pressure, an evaluation of the retina, and a measurement of the eye length to determine the correct replacement lens. The eye will be dilated so that the surgeon can examine the eyes for all signs of cataracts.
