Intro on what is cataracts (link to previous article)
As mentioned in the previous article here(link) cataracts are another cause of vision impairment amongst the elderly. Cataracts appear as protein in the eye starts to degenerate due to age, which causes a cloudy appearance, due to a protein deficiency in the eye which causes a cloudy or foggy appearance. This obstructs the vision of the person.
How does cataract surgery work
A cataract surgery is basically extracting the bad part, the cataract, and inserting a new artificial lens. The way it works is a simple process.
Step 1 – The ophthalmologist will use a laser called a LenSx to make an incision in the cornea(transparent part of the eye that covers the front).
Step 2 – After making the incision in the cornea, the LenSx will make a circular opening in the front of the lens.
Step 3 – Next the LenSx breaks apart the cataract into smaller pieces. This is to aid with the removal.
Step 4 – The surgeon will then proceed to remove the cataract with an ultrasonic probe via suction.
Step 5 – Thereafter the ophthalmologist inserts a new lens through the micro-incision. The lens to be inserted will either be a monofocal or multifocal IOL.
Step 6 – when the surgery is completed the surgeon will check the focus on the retina to insure the focus is clear.
Who are suitable and not suitable candidates
In order to determine whether you are eligible for a cataract surgery you would need to be examined by a certified ophthalmologist. But even before that if you suspect you might suffer from cataracts you could check to see how many the following are applicable to you:
- Are you over the age of 40; and
- Do you have double vision in one eye
- Do you see colors as being very faded
- Are you sensitive to light?
- Do you have poor night vision?
If some of these are present you might need to see a doctor.
Unfortunately not everyone will be able to get cataract surgery as some people might be disqualified due to a variety of reasons:
- Individuals with pre-existing eye conditions
- Advanced diabetes
- Corneal diseases
- Macular degeneration
Even though no current preventive treatment for cataracts exists and surgery being the only option, a conservative approach to cataracts is still advised. A conservative approach to cataracts means that ophthalmologists will make absolutely sure that a candidate is eligible for and absolutely needs to have surgical intervention.
Ophthalmologists will run a series of extensive tests. The first test will be conducted to determine the presence of pre-existing conditions or comorbidities that might hamper the final outcome. In some cases the ophthalmologists might determine that a patient is too young and might need to wait some more time in order to have the cataract removed for optimal results.

Do you have a spam problem on this website; I also am a blogger, and I was wondering your situation; many of us have developed some nice procedures and we are looking to trade methods with others, be sure to shoot me an email if interested.
Great blog you have here but I was curious if you knew of any discussion boards that cover the same topics discussed in this article? I’d really love to be a part of community where I can get opinions from other experienced people that share the same interest. If you have any suggestions, please let me know. Bless you!
Thanks for the ideas you reveal through this website. In addition, several young women who seem to become pregnant will not even attempt to get medical health insurance because they have anxiety they would not qualify. Although a lot of states currently require that insurers supply coverage in spite of the pre-existing conditions. Costs on these kind of guaranteed programs are usually larger, but when considering the high cost of health care bills it may be your safer strategy to use to protect your current financial potential.
I must thank you for the efforts you’ve put in writing this website. I really hope to see the same high-grade blog posts from you in the future as well. In fact, your creative writing abilities has motivated me to get my own, personal site now 😉
