In the past, patients who had undergone cataract surgery were only able to see with the help of very thick glasses. Even with these bulky lenses, their vision was often still very poor. Today, however, intraocular lenses (IOLs) allow cataracts patients to enjoy sharp, clear vision, reducing or even eliminating the need for glasses. If your vision has been compromised by cataracts, you may benefit from the range of IOLs that we offer at our Philadelphia practice. With monofocal, multifocal, and Toric lenses available, we will work with you to help you choose the right ones for your needs. We also offer the advanced Tecnis Symfony IOLs that allow patients with an extended depth of focus, thus improving visual acuity at near, intermediate, and far distances. Contact us today to schedule your appointment. Our doctors look forward to helping you improve your vision!
Cataracts occur when clumps of protein gather in your natural crystalline lens, causing it to become clouded. When the lens is clouded, vision becomes distorted. If you suffer from cataracts, you may experience blurred vision, double vision, faded colors, halos, and trouble seeing at night. Temporary measures can be taken to maintain vision, but permanent correction of this progressive condition can only be achieved with surgery. Our ophthalmologists remove the damaged lens and replace it with an artificial intraocular lens. We offer both traditional and laser cataract surgery procedures to accommodate our patients.
Monofocal IOLs were the first type of intraocular lens, and they provide vision correction at only one distance. Many patients use these lenses for far distances, and will wear reading glasses, if necessary, for close vision. If you are having cataract surgery performed on both eyes, you may choose to have one eye implanted with a distance-vision IOL and the other implanted with a IOL for near vision. Your eyes will naturally make the adjustments needed to send clear images to your brain. This technique is called monovision, and if you are considering this solution, we advise that you try it with contacts before your cataract surgery.
Multifocal lenses have a series of focal rings, allowing for better vision at both near and far distances, and often reducing reliance on glasses. Side effects with multifocal IOLs are rare, but some patients may experience difficulties with glare and blurred vision. If you frequently drive at night, or rely most frequently on close-up vision for work, you may be better suited for monofocal lenses.
Astigmatism occurs when your cornea is irregularly shaped, distorting your vision at all distances. If you suffer from this condition, Toric IOLs, which are equipped with astigmatism correction, are your best option. For further vision enhancement, you may also choose to undergo limbal relaxing incisions, which reshape your cornea. For your convenience, this procedure can be performed during your cataract surgery, or you can choose to have it performed at a later date.
The Symfony IOL is a unique innovation that provides focus at a range of distances with no "breaks" in between. As the patient changes focus, clarity remains fluid. Meanwhile, the device results in little or no higher-order aberrations. For astigmatic patients, the Symfony IOL is also available in a toric version.
