Using the most up to date methods and instrumentation, cataract surgery is typically performed using a small incision, phaecoemulsification technique. This means that the cataract surgery is accomplished using the smallest possible incision, and removal of the lens material is accomplished using an ultrasonic needle. There is a common misconception that cataract surgery is done using a laser. This is not the case, and has never been the case. The use of laser energy produces too much heat to be adapted for this purpose, and would cause irreversible damage to the delicate tissues inside the eye.
Intraocular lens come in a variety of materials and designs. Your surgeon generally chooses a lens made of a material that is best suited to your individual situation. All intraocular lenses used in our practice are coated with UV filters. Some lenses are yellow in color. These lenses are theoretically better at blocking the light rays in the blue spectrum which are thought to be related to the development of macular degeneration in some patients. Some intraocular lenses are designed to be multifocal in certain lighting circumstances, which may enable patients to see both at distance and near without the aid of spectacles. This effect has been shown in all patients in whom the lens has been implanted, and it is once again important for patients to realize that while cataract surgery with intraocular lens implantation frequently results in a reduced dependency on eye glasses it is never guaranteed to eliminate this need totally.

Following proper dilation of the pupil and preparation of the surgical area using betadine or other cleansers, a topical anesthetic is administered to the surface of the eye. An incision of 2.5 to 3 millimeters in length is then created at the junction of the cornea (the clear domed structure on the front of the eye) and the sclera (the white part of the eye).
Another dose of anesthetic is then administered inside the eye through this incision. The front part of the lens envelope, know as the lens capsule, is carefully opened so that the lens material can be removed. This is accomplished using a needle-like ultrasonic device, which pulverizes the hardened and yellowed lens proteins. The pulverized material is simultaneously vacuumed from the eye.
Once all of the cataract material has been removed, and assuming that the lens capsule which was opened at the beginning of the surgery remains strong enough to support the lens implant, a folded intraocular lens specifically chosen by the surgeon to suit your individual needs is then inserted through the original incision and maneuvered into the lens capsule and then centered. The lens will remain inside your eye in this location without moving. Intraocular lenses cannot be felt or sensed in any way by the patient.
In most cases, once the lens is centered within the lens capsule, the instruments are removed, and the surgery is therefore complete. Under most normal circumstances stitches (or sutures) are not required to keep the incision sealed. Should the incision require a suture to be placed for proper sealing, this suture is generally removed within the first week following surgery.
Recovery from surgery is generally very quick, with most patients achieving noticeably better vision within the first 24 hours of the procedure. Patients are generally asked to use two different eye medications, administered as drops several times daily for the first few weeks after surgery. It is important that during the first 7 post-operative days patients refrain from strenuous activity such as lifting weights for exercise or lifting other heavy objects. Patients should also refrain from eye rubbing during the first few weeks following surgery.
If glasses are required following surgery to achieve the best possible vision either for close up work such as reading, or for distance purposes, these will be prescribed three to four weeks after surgery when full recovery is expected. If both eyes are scheduled to have surgery within a few weeks of each other, then glasses, if needed, will be prescribed following full recovery of the second eye.
The AcrySof ReSTOR lens is a foldable IOL that represents breakthrough technology because of its unique, patented optic design, which allows patients to experience the highest level of freedom from glasses ever achieved in IOL clinical trials.
The AcrySof ReSTOR IOL uses a combination of three complementary technologies: apodization, diffraction and refraction, to allow patients to experience a full range of high-quality vision without the need for reading glasses or bifocals. This range of vision without glasses is achieved through the optical properties of the IOL.
The benefit for patients is a high level of spectacle freedom. Alcon has patented the application of apodization technology to an IOL, making the AcrySof ReSTOR lens the first and only apodized diffractive IOL.
During U.S. clinical trials, the results with ReSTOR were remarkable:
We provide the technology that makes freedom from all glasses possible when Lasik does not apply.
The ReSTOR lens, a multifocal implant with so-called apodized diffractive lens, the CrystaLens, an accommodative implant, and the ReZoom lens which is another multifocal lens do much to free people of the need for glasses not only for long vision but also for reading and intermediate vision.The Verisyse lens implant and the Visian ICL implant both are designed to bring excellent distance vision for people who do not have cataracts and whose eyes are too nearsighted to be adequately helped with LASIK.
The Center for Corrective Surgery are proud to announce the arrival of this amazing new implantable contact lens that can correct beyond the actual limits of lasers. If you are a highly nearsighted patient this may be the procedure for you. If you have been told you cannot have LASIK this might also be a procedure for you. We are committed to the latest technology at our center and this new lens simply can provide the same benefits that LASIK has brought to millions.
Introducing a solution for patients with high amounts of nearsightedness. The ICL is a revolutionary refractive lens that can correct vision up to –15 diopters of nearsightedness. The ICL procedure has been repeatedly improved through years of studies and continued refinement. This lens is a posterior chamber implant that is situated behind the iris and in front of the natural crystalline lens. It is also know as a Phakic IOL. The surgery is performed on an outpatient basis, which means that a patient has surgery and leaves the same day.
Prior to the surgery a surgeon will make two microscopic holes in the iris. Your eye will be numbed with a light, topical or local anesthetic. Once the eye is numbed the surgeon will make 2 side port incisions and one main temporal incision that is critical to the insertion process. Next the surgeon will insert the ICL through the main temporal incision and place the lens behind the iris and in front of the crystalline lens. This insertion procedure is typically performed one eye at a time. There is very little discomfort and normally no pain associated with the procedure. Some drops or perhaps oral medication may be prescribed and a visit is usually scheduled the day after surgery. Patients will be advised to arrange for someone to drive them to and from surgery.
Individuals who suffer from extreme nearsightedness will have a solution for their poor vision. The ICL provides an opportunity to those individuals who are not candidates for lasik eye surgery. Some people cannot have lasik for reasons ranging from high prescriptions to thin corneas. The ICL will now give these patients the opportunity to experience the same lifestyle change that lasik has brought to millions.
You're likely a good candidate for ICL if:
As a rule, damage caused by glaucoma cannot be reversed. Eye drops, pills, laser, and surgical operations are used to prevent or slow further damage from occurring.With any type of glaucoma, periodic examinations are very important to prevent vision loss. Because glaucoma can worsen without you being aware of it, your treatment may need to be changed over time.
Glaucoma is usually controlled with eye drops taken several times a day, sometimes in combination with pills. These medications decrease eye pressure, either by slowing the production of aqueous fluid within the eye or by improving the flow leaving the drainage angle. For these medications to work, you must take them regularly and continuously. It is also important to tell all of your doctors about the eye medications you are using. Glaucoma medications can have side effects. You should notify your eye doctor immediately if you think you may be experiencing side effects.
Some eye drops may cause:
* A stinging sensation
* Red eyes
* Blurred vision
* Changes in pulse, heartbeat or breathing
Pills sometimes cause:
* Tingling of fingers and toes;
* Loss of appetite;
* Bowel irregularities;
* Kidney stones;
* Anemia or easy bleeding.
Laser surgery treatments may be effective for different types of glaucoma. The laser is usually used in one of two ways.
In open-angle glaucoma, the drain itself is treated. The laser is used to enlarge the drain (trabeculoplasty) to help control eye pressure.
In angle-closure glaucoma, the laser creates a hole in the iris (iridotomy) to improve the flow of aqueous fluid to the drain.
When operative surgery is needed to control glaucoma, your ophthalmologist, a surgery trained eye MD uses miniature instruments to create a new drainage channel for the aqueous fluid to leave the eye. The new channel helps to lower the pressure. Though serious complications of modern glaucoma surgery are rare, they can occur, as with any surgery. Surgery is recommended only if your ophthalmologist feels that it is safer to operate than to allow optic nerve damage to continue.
Treatment for glaucoma requires a “team” made up of both you and your doctor. Your eye doctor can prescribe treatment for glaucoma, but only you can make sure you take your eye drops or pills. Never stop taking or change your medications without first consulting your eye doctor. Frequent eye examinations and tests are critical to monitor your eyes for any changes. Remember, it is your vision, and you must do your part to maintain it. Loss of vision can be prevented. Regular medical eye exams may help prevent unnecessary vision loss.
You should have an examination:
* Every 2 years
* If you are age 39 and over.
* If you are age 50 and over
* If a family member has glaucoma
* If you are of African ancestry
* If you have had a serious eye injury in the past
* If you are taking steroid medications
The FDA approved the CrystalLens accommodative intraocular lens on November 15, 2003. Our center has been awaiting the approval of this lens which helps us correct the vision of one group of people whose eyes are beyond the range of lasik.The CrystalLens helps those who want to be rid of the need for bifocals and whose eyeglass prescription is beyond the range of LASIK. The lens actually moves minutely back and forth within the eye as a result of the action of the eye’s focusing muscles.
