In trained hand it is safer because of reduced risk of injury & infection to eye.
No. this surgery is best performed in early stages of cataract and there is no need for the cataract to get matured. Hence the patient need not wait till a near stage of blindness. Also harder the cataract, the harder it is for the surgeon to remove it.
Since this surgery involves very few loss of working days and early resumption of routine activities, this surgery proves to be cheaper.
Yes, this can be performed without any difficulty or any effect on the previously operated eye.
Yes, it is a surgery of choice for them.
No, there are few exceptions specially if the cataract is very mature and hard.
Usually the Spectacles are required for near vision and occasionally for distance vision.
Crystalens is an intraocular lens that, unlike a standard IOL, can treat both a person’s cataracts and a person’s presbyopia (loss of near and intermediate focusing ability). You probably noticed in your forties that you started to lose some of your up-close vision and had to start wearing reading glasses; this was due to a loss of accommodation. Crystalens is designed to recreate your accommodation and reduce or eliminate wearing glasses. With the unique Crystalens, you can enjoy activities such as: reading a book, working on the computer, and driving a car.
Crystalens replaces the eye’s natural lens and is designed to mimic the eye’s natural focusing ability, thereby enabling vision across a broad range of distances comparable to a healthy eye. As with the natural lens, Crystalens accommodates, or moves and flexes, in response to ciliary muscle contractions in the eye. These contractions drive forward movements of the lens so the eye can maintain a clear image as it focuses on near, intermediate and far objects.
In the past, cataract surgery was only able to treat a patient's cataracts, so patients would still be dependent on glasses for most of their daily activities, especially for up-close and intermediate activities. Crystalens will correct more than just your cataracts. Crystalens can offer you a fuller range of vision and reduce or eliminate your dependence on glasses.
If your eyes are healthy, you have not had previous cataract surgery and you have no major health problems, you may be an excellent candidate for Crystalens. Your doctor will perform a thorough exam and advise if Crystalens is right for you.
Crystalens is the only accommodating intraocular lens on the United States market. As with the natural lens, Crystalens accommodates, or moves and flexes using an innovative design, in response to ciliary eye muscle contractions. These contractions drive forward movement of the lens as it focuses on near, intermediate and far objects.
No surgeon can guarantee 20/20 vision because everybody’s eyes function differently. However, our patients have been reporting excellent results and most enjoy the majority of their activities without glasses.
Since everyone’s vision, expectations, and lifestyles differ, it is difficult to determine how much you will be dependent on glasses. If you are like the majority of Crystalens patients, you should be able to experience the same quality vision you did when you were younger, with minimal or no dependence on glasses after Crystalens surgery.
Crystalens works similarly to your natural lens in that it delivers 100% of available light rays at all distances -- near, far, and intermediate. Unlike many multifocal IOLs on the market, lighting conditions have very little impact on patients with Crystalens. Crystalens directs all available light received by the eye to a single focal point, resulting in quality of vision comparable to a healthy natural lens. Patients have reported very minimal disturbances. However, it is recommended that you use good lighting when reading.
All IOLs, including standard monofocal IOLs, can create some degree of halos and glare. Glare and halos have sometimes been observed with the Crystalens. However, unlike a multifocal IOL, Crystalens works similarly to your natural lens in the way it delivers available light rays at all distances -- near, far, and intermediate. As a result, Crystalens patients typically experience fewer halos and less glare than a multifocal IOL patient.
Insurance coverage varies greatly from policy to policy. Generally speaking, private insurance and Medicare will cover the cataract surgical procedure and may also allow a certain additional amount for a standard lens implant. With Crystalens, you are receiving an additional benefit of presbyopia correction that will allow you to enjoy a fuller range of vision with decreased dependence on glasses. You will be responsible for paying for the presbyopia correcting portion of the surgery, which is not covered by Medicare.
In the Crystalens clinical trials, patients reported good intermediate vision. Most Crystalens patients are able to see their computers, dashboards and anything else at arm’s length without glasses.
Crystalens surgery is permanent and there is no evidence that the lens will stop working over time. Patients have had Crystalens implanted in their eyes for nearly 7 years with no change in its ability to flex. It is an extremely well-tested and durable design. In fact, there is clinical evidence to support that most patients' vision continues to improve with time.
Every patient is different and only your surgeon can fully explain the details of your Crystalens procedure. However, the following information may be helpful for most patients.
Typically cataracts will develop in both eyes, and we recommend that the surgery be done in both eyes. Usually you will have surgery on the second eye within 2 weeks of the first eye.
Cataract surgery is typically an outpatient surgery. The actual surgery itself is approximately 15-20 minutes.
No. Topical anesthetic drops will be placed in your eye and oral medications may be administered to help you relax.
Typically you will be able to return to normal activities within several days. You should be able to drive and return to work within 2-3 days. Your eyes may be sensitive to the touch for a few days, and you should avoid strenuous activity and rubbing your eye. It is important to avoid lifting or straining that would increase pressure on your eye. You can shower, but avoid getting soap in your eyes. Refrain from eye makeup for several weeks. You should also avoid public pools and hot tubs.
Patients vary widely in how they are affected during the recovery phase. For example, for some patients it takes longer for their near vision to come into focus, while others achieve great near vision almost immediately. The best way to learn about the recovery period is to talk to your surgeon about the procedure.
Your doctor will advise you based on your procedure. Typically, the doctor will see you one day after surgery, after 2-4 weeks and again around 3-6 months after surgery. Thereafter, an annual exam is sufficient.
Once your cataracts are removed and replaced with an IOL, you will never need to have cataract surgery again. Occasionally, several months after the lens has been placed in the eye, your vision may start to become cloudy again. This can happen with any type of IOL. This is sometimes called a secondary cataract and refers to the clouding of the membrane that surrounds the implant. Your surgeon will go in and quickly remove the clouded cells. This is done painlessly in an outpatient environment and usually takes just a few minutes
