Approximately 3.5 million cataract operations are performed in the US each year, making it one of the most commonly performed surgical procedures in the country. Cataract surgery is highly successful in restoring vision and improving quality of life for patients.

If someone has already had successful cataract surgery and requires LASIK to improve myopia (nearsightedness), hyperopia (farsightedness) or astigmatism, the LASIK procedure would reshape the front of the cornea and should not adversely affect the prior cataract removal and lens implant surgery if LASIK is done after the eye has completely healed from cataract surgery.

However, for someone who has previously had LASIK and is now considering cataract surgery, it is not so simple. LASIK reshapes the cornea and corneal measurements are used to calculate the intraocular lens used to replace the cataract. Unfortunately, the calculations currently used do not work as well after LASIK (or other refractive surgery). So, anyone who has previously had corneal refractive surgery prior to cataract surgery may need it again after cataract surgery.

For further questions, you should ask your surgeon.

role of risk factors in visual outcome after cataract surgery

Continuing to smoke after surgery greatly heightens a person's risks of complications, such as infections in the surgical incision. In one study, more than half of patients who continued smoking after surgery developed complications compared to less than 20 percent who quit. Plus, fewer complications means less time in the hospital for patients who kick the habit.

a cataract is steep rapids formed by cliffs in a river.

A cataract is caused by an opacity of the crystalline lens. The lens becomes cloudy and will not allow proper light to transmit through it. It is like having a dirty windshield. You won't see any better, until you have it surgically removed. Many people believe that cataracts are caused by exposure to ultraviolet light. That is why most people in the coastal regions have a higher tendency to have cataracts- they are outside more often. And usually cataracts are found in older adults- because their eyes have been exposed to the ultraviolet light for a number of years. But cataracts cal also be caused by other things, not just ultraviolet light. An annual dilated eye exam should be performed by an Optometrist or Ophthalmologist to check for refractive errors and any diseases or problems with the eye.

Why would you need contacts after the surgery? You need to ask your doctor about this one.

The only thing that helps cataracts is surgical removal. If somebody tells you a pill or drop can reverse the effects of a cataract, they are lying to you. Most insurance companies will not cover the cost of a cataract surgery unless your vision is worse than 20/40 in the affected eye. But that all depends on your insurance company.

Flash Burn and Blindness

Pellegra is associated with a deficiency of the B vitamin -- niacin . To cure it, one would add niacin to their diet. The body can also make niacin from the amino acid (a protein building block), tryptophan. Pellegra is rare unless there is an overall deficiency of food, vitamin and mineral intake including tryptophan and niacin.

A new floater after cataract surgery could indicate presence of retinal tear or hole. When associated with flashes of light or a "curtain" over the visual field, floaters are especially concerning. Retinal holes or tears may lead to retinal detachment and eventually, loss of vision, if not properly managed. Therefore, it is important to let one's eye surgeon know of any significant eye problems after surgery for early detection and treatment.

Genetic defects or an infection or disease in the mother during pregnancy are among the causes of congenital cataracts.

YAG capsulotomy is most often used for this type of cataract.

A cataract landform is a riverine or fluvial feature, where the river tumbles down over a series of boulders or small waterfalls.

Each insurance plan is different. And there are many, many plans within BCBS. If you are covered by your employer with BCBS, the benefits and exclusions are decided upon by your provider. Before you make any decisions about your healthcare, you need to go straight to the horse's mouth. If you are already covered by BCBS, call the Member Services line on the back of your card. They can tell you if a certain diagnosis is covered or not. You should have received a benefits booklet at the time you signed up for the health insurance that also explains all the covered benefits and those that are excluded. If you are just shopping for individual insurance, BCBS will determine if you are eligible for any particular procedure, or if you have already had several large claims for a certain illness, they may add a "rider" to your policy that says they won't pay for that particular diagnosis for a certain length of time, if ever. Group health insurance that is employer-provided is usually the most comprehensive.
