Cataract surgery is quite routine these days. Generally you will be asked not to eat for a certain time before the surgery, and may be given eyedrops to use prior to your appointment. At the hospital or eye clinic, the eye will be numbed with an injection or eyedrops and the area around your eye will be cleansed. Most people are awake through surgery but may be given something to help them relax. The doctor will use tiny incisions to reach the lens of the eye, which will be broken up and removed. A new lens will be inserted. The operation takes less than an hour most of the time. After the operation, you will be able to rest and recover, and a patch may be placed over your eye. Most people can go home afterward, although someone else will need to drive. There will be no stitches to remove later, but you will have to use special eyedrops to prevent infection, and probably have to sleep with a shield over the eye. You will be given a list of things not to do, like rubbing the eye or bending over to pick up objects or lift any heavy objects. Healing will take eight weeks, and your doctor will monitor your progress.

Healthy Humans answeredSee All 2 AnswersIn adult-onset diabetes mellitus, cataracts are very common. The two reasons for this increased prevalence is the fact that high blood sugars affect the health of the lens of the eye, and diabetics are evaluated more often than the rest of the population.
High levels of blood sugar eventually get into the fluid in the eye-raising the level of the sugar in the crystalline lens. This will draw water into the lens and the lens will swell. Also, sugar will form alcohol in the lens creating lens opacities, which we call cataracts. The cataract is actually a break down of the protein structure in the lens, and high sugar and alcohol content will increase this phenomenon. The same is true for people who indulge in excess alcohol.
For this reason, all diabetics should try to maintain a normal blood sugar. Furthermore, the UV portion of sunlight creates cataracts. Many medications such as steroids accelerate cataract formation. So always ask your pharmacist whether you are taking a photosensitizing medication. The good news is that sunglasses will block sun related cataract formation. Look for sunglasses that block UVA and UVB.
Insurance companies and family practitioners request an annual eye exam for all diabetics. Therefore, it is far more likely that early cataract formation is detected in this group of people.Remember through nutrition and specific supplementation cataracts can be stopped in many cases.

Sigma Nursing answeredSee All 2 AnswersUnfortunately, there are no medications that can help treat cataracts. At least for awhile, eyeglasses and contacts can help with some of the vision problems that result from a cataract. However, surgery is the only successful treatment option to successfully get rid of a cataract and restore a person's vision

Itching and mild discomfort are normal after a cataract surgery. Some fluid discharge is also common. Your eye may be sensitive to light and touch. If you have discomfort, your doctor can suggest treatment. After one or two days, moderate discomfort should disappear.
For a few days after surgery, your doctor may ask you to use eyedrops to help healing and decrease the risk of infection. Ask your doctor about how to use your eyedrops, how often to use them, and what effects they can have. You will need to wear an eye shield or eyeglasses to help protect your eye. Avoid rubbing or pressing on your eye.
When you are home, try not to bend from the waist to pick up objects on the floor. Do not lift any heavy objects. You can walk, climb stairs and do light household chores.
In most cases, healing will be complete within eight weeks. Your doctor will schedule exams to check on your progress.

The prognosis for cataracts is quite good. Cataracts are not known to cause death. They are generally easily treated via lens replacement surgery. This surgery is well tolerated and generally leads to substantial improvment in people's lives.

See All 2 AnswersDuring cataract surgery, the actual structure that forms the cataract is removed, and an implant is put in its place. That cataract cannot come back. However, after cataract surgery, sometimes the thin layer that sits behind the implant can become cloudy, and some people refer to this as a "second cataract." This thin cloudy layer can be addressed in the office with a laser procedure.

Cataract surgery is an elective, outpatient surgery in which a clouded lens in the front portion of the eye is surgically removed and replaced by an artificial lens. It is typically performed under light sedation and not general anesthesia.
In the eye the lens helps to focus eyesight. A cataract is the clouding of this lens, which is normally clear. The clouding of the lens is a result of aging and can be accelerated by sun exposure over time. This progressively blurs and clouds vision.

The time for cataract surgery is when the visual impairment reaches the point of altering your life activities (like driving at night or seeing street signs), or interferes with your ability to read, watch TV, or do other activities that are important in your daily life. Cataract surgery is one of the safest major surgeries that can be performed, with a success rate of greater than 98%, but complications and risks can be associated with every operation. Cataract surgery is rarely an emergency and can often be delayed, but remember, the longer one delays cataract surgery, the more dense (hard) the cataract will become, and this will make the operation more difficult for your eye doctor to perform in a safe manner.
