A person has 30 % lens opacity on one eye. How do we correct his opacity ( cataract ) without a lens implant

A cataract is a natural aging condition of the lens.  The lens is the part of your eye that changes shape to allow you to focus to see things when you hold them close to you.  The lens is basically a sack with a bunch of cells in the center.  Over time, these cells grow and divide causing the sack to be more and more stuffed full off cells.  As the number of cells in the lens increases, the body can no longer get enough nutrients into all the cells and their metabolism slows.  These cells all pump water out of the lens to keep it dehydrated and clear.  So as their metabolism slows, water accumulated in between the cells of the lens causing it to become cloudy.  In fact, the word "cataract" in latin means "waterfall" because that is what the Romans and early doctors described the vision as becoming.\n\nTo treat a cataract, the best current solution is cataract surgery.  They don't take out the whole lens, just the cells and water in the center (leaving the sack there to hold the implant lens in place).  It is most commonly currently done with only a 3 mm incision.  Most surgeons will finish the procedure in about 10 minutes and there is no pain.  These are done in the US with about a 99+% success rate.  The implant lens they put in will be focused for your eye, so usually little or no eyeglass prescription needed after the procedure (except for reading glasses).  \n\nI know surgery is scary, but as surgeries go this is one of the easiest to go through.  Also, this approach is too quick, easy and successful to want to play around trying anything else.

Well, in a matter of speaking. Those of us who are myopic (nearsighted) become so dependent upon our glasses or contacts, that we really can't see without them once we start wearing them.

Consider laser vision correction or contact lenses

It's fine. You don't even need glasses at that point unless your having trouble with night-vision. You don't really need glasses until your 20/30 at least. :)

I am not sure about this, but your lens may be beginning to cloud, which can lead to blindness or a cataract....I highly recommend that you see your eye doctor immediately. Problems with the eyes are serious. You should consult a doctor as soon as possible.

Dear Tim,\nOnce you cross 40 years it is not recommended to wear an extended wear contact lenses because your metabolism doesnt permit that. That is one reason why not many companies manufacure bifocal contact lenses with extended wear modality. If you really want a bifocal EW, u can get it done by your own Optometrist but in a Rigid Gas permeable material which will be specifically designed to suit your own need.\n\nJ&J's Acuvue bifocal when earlier lauched was launched as a Flexible wear lens (lenses with which you can take a nap)\nO2 Optix is a silicon hydrogel a newer material which is specifically made for EW modality\n\nJ&J's Acuvue Advanced and Oasis are again next generation EW silicon hydrogel materials.\n\nCIBA vision will soon be launching their new EW multifocal. But God knows how much time it takes.\n\nContact lens availability also depends on the country you live in. If you are in India, you definitely have a very few options left with you even with a multifocal/bifocal lens.\n\nZubin J\nOptometrist

You may or may not need glasses.  Very likely you only need to practice good strain-relief for your eyes (rest them regularly, high quality drops, etc.).  But, to be safe, get an eye exam and tell the ophthalmologist what you are doing on the computer and how long you are doing it.

If you have decided to buy from India, any good ophthalmologist in Bangalore should be able to check your eyes & give you a number for lenses. You could ask for Bausch and Lomb soft contact lenses. They usually suit most people but you might wanna ask your doc which ones are best for you. They usually order for you and give you one for trial for a week or so. \nHowever, I would really recommend that you get your check ups done and buy your lenses where you are gonna live because you may need to go back and forth to your doc in case the lenses are not fitting properly. \nAlso FYI, avoid using Bausch and Lomb's cleaning solutions for a while as there was recent news about some possible contamination that caused blindness in some people in USA. \nAs far as difficulties in wearing contact lenses, it depends how good your lenses are. You really need to be hygienic with those--nothing to sweat about, just follow the directions from your doc. You may consider buying sunglasses for times when you wearing lenses in windy situations.

Absolutely!  I just had it in Feb and it's the most amazing thing in the world to be able to see normally without glasses or contacts.  Do your research first and find a board certified surgeon - this is not the time to look for sale prices.  There is nothing to be scared of, it does not hurt at all and it's done in like 2 minutes per eye.  Good luck!

Partly blind.   If you are partly blind, you must get a certified statement from an eye doctor or registered optometrist that: \nYou cannot see better than 20/200 in the better eye with glasses or contact lenses, or\n\nYour field of vision is not more than 20 degrees. \n\n\n  If your eye condition will never improve beyond these limits, the statement should include this fact. You must keep the statement in your records. \n\n  If your vision can be corrected beyond these limits only by contact lenses that you can wear only briefly because of pain, infection, or ulcers, you can take the higher standard deduction for blindness if you otherwise qualify.

The treatment approach to keratoconus follows an orderly progression from glasses to contact lenses to corneal transplantation.   Glasses are an effective means of correction mild keratoconus.  As the cornea steepens and becomes more irregular, glasses are no longer capable of providing adequate visual improvement.  Corneal transplant surgery is indicated when a person cannot wear contact lenses for an acceptable period of time or when the vision, even with contacts, is unsatisfactory.  Over 90% of corneal transplants are successful with the majority of people obtaining vision of 20/40 or better afterwards with either glasses or contact lenses. A gas permeable contact lens is the most highly effective way to manage keratoconus and 90% of all cases can be managed this way indefinitely. If the cornea becomes too scarred or painful, a corneal transplant may be necessary.

I don't think so.  I have terrible eyesight.  I can't even see the big\n"E" on the eye chart!  I am very nearsighted.  I am in my mid 30's and have had the same prescription for several years now.\nI think it's because I do as much reading as possible without my glasses and I don't wear contacts anymore.  My sister, on the other hand, gets a new prescription every year and it's always worse.  I have heard of some kind of eye exercises advertised on the radio that supposedly restore at least some sight.  I'm sorry I can't be more specific.

This is very bad for the corneas. Abrasions of the corneas with opacities can occur. Tell the person to stop this habit. MD

Yes it is possible but it is time consuming. Basically, you need to create a new layer and try to work with the same color that the surrounding eye is. Then adjust the transparency until it matches closely and doesn't look odd at 100%.\n\nOn the other hand, if you download Picasa from Google, there is a red-eye tool and it works very well.

The only proven ways to do this is by laser refractive surgery (LASIK) and orthokeratology (ortho-K).  LASIK uses a laser to reshape the front of the eye (the cornea).  Ortho-K uses gas permeable contact lenses to temporarily flatten the cornea.  Contrary to popular belief, vitamin A and other supplements will not help you with this.  You really should discuss your concerns with your eye doctor.  He/she can recommend options that will work for your eyes.

no- your eyes will stabalise at one level, unfortunetly they wont ever improve. corrective lenses can help as can laser surgery

The person who does not use glasses has an eye that is curved to focus light almost exactly on the retina.  The person who does use glasses has eyes that focus light either in front of or behind the retina, and the glasses change the focus of the system to coincide with the retina as in a person who does not require vision correction.
