An intraocular lens, known as an IOL, is implanted directly in the eye. It is used to replace the eye’s natural crystalline lens when it becomes clouded over by a cataract. IOLs are also used as a form of refractive surgery to enhance the optical power of your eye. The following three IOLs are used to replace lenses damaged by cataracts and presbyopia (middle-aged vision). Crystalens® This procedure takes 15-45 minute per eye and is done with local anesthetic. It is ideal if you require good night vision, and don’t mind the possibility of having to wear reading glasses despite your IOL. You can usually resume your normal activities the day after surgery. Distance recovery is immediate, but you should allow weeks for computer and reading distance to recover fully. Benefits • Stable, long term outcomes
• Best clarity of vision
• Eye focus is similar to natural focus
• Good distance vision, computer vision, and night vision Limitations Crystalens is a more difficult procedure and can have poor improvement for reading-range vision. It can also take your eyes up to a year to fully adapt. ReSTOR® This procedure takes several hours to complete both eye. It requires local anesthesia, and you can return to your normal activities the next day. However, most surgeons advise taking one or two days off work. You can immediately enjoy improved general, computer and reading distance vision. Benefits • Near and far focusing is improved so greatly, that you may no longer need glasses or contacts again
• Ideal for reading small print and seeing objects close up
• Good distance vision Limitations ReSTOR can have poor results for improvement in computer distance and night vision. Clarity is also not as crisp as with other IOLs. You may still need glasses to read small print. ReZoom™ This procedure takes about 15 to 45 minutes for each eye and uses local anesthetic. There is a wait of three to eight days before the second eye is corrected. ReZoom also enables you to resume your normal activities the day following surgery. Complete vision recovery takes anywhere from one to two weeks, while your eyes adjust to their new lenses. ReZoom creates multiple focal points, so distance is improved at all distances. Benefits • Immediate improvements to general, computer and reading distance vision
• Best independence from glasses and contact lenses compared to other IOLs
• Good overall vision quality Limitations ReZoom may make only moderate improvements to computer distance vision. Reading range vision is improved, but only moderately. Night vision and clarity can be poor. You may also experience temporary halos or glare, and still need glasses to read fine print. Am I a good candidate? If you are in overall good health and are suffering from cataracts or presbyopia, you may be a good candidate for lens implant surgery. If you have chronic infections, uncontrolled diabetes, or any other type of health problems, you may possibly still have this surgery—but your condition must be under control first. If you have had previous refractive surgery such as LASIK, you may be a candidate for IOL surgery, providing your eyes are now in good health. Your initial examination and consultation will determine your candidacy for these procedures. If you are interested in implantable lenses, you can learn more about them at Horizon Eye Care. The experienced staff will be happy to answer your questions and can schedule your initial consultation. Clear vision may be just a click or two away.
