Can Cataract Lens Be Replaced
Cataract: 48 M from VT asks: Is there any danger in me not having my lens replaced, it has a cataract.? ANS: Yes you may be blinded at night by car lights and kill yourself or others. But your eye Dr who knows what your cataract looks like and is doing. Listen to them. But usually no danger until it begins to affect vision esp night lights. ...Read more
Occurs whent here is a clouding (or change in protein composition) of the normally clear lens (which is located behind the pupil and iris) inside the eye. Cataracts are most commonly due to aging, but can be congenital (born with it), due to trauma or uveitis (eye inflammation). Can be worsened by long-term topical steroid ...Read more
Usually: Lenses are rarely put in the wrong place after cataract surgery, even when it is complicated and there are problems. Lenses get out of place when there are variations in the internal anatomy of the eye, fragile components which are unpredictable and some degrees of trauma. These can usually be fixed at a second surgery. ...Read more
Yes: With the right selection of patient to receive this lens and the proper expectations of the type of vision to be expected, this has been a helpful addition to this surgery. It is gradually becoming more commonplace and the available lenses are continuously being improved. Note that it is an extra personal expense not covered by insurance or medicare. Discuss with you eye surgeon. ...Read more
Can you tell me if you've seen anyone who undergone cataract surgery and replaced the lens with accommodative iol. How do you feel the result?
Accommodative IOL: Crystalens & Trulign Toric (by Bausch + Lomb) are only FDA-approved intraocular lenses (IOLs) that use a method called accommodation (IOL tried to mimic back & forth movement of natural lens in capsular bag). These pts should see better at near & intermediate without glasses compared to those who had a monofocal IOL: more info: eyedoc2020 blogspot com ...Read more
I wear eyeglasses for distance. If I get cataract surgery to replace the lens, only, will I still need eyeglasses after cataract surgery?
Is Intraocular lens medically necessary for 70yr old's cataract removal? Doc is forcing mom to replace her natural lens during cataract surgery.
Absolutely. If your mom doesn't get an implant after her surgery, she will be blind without wearing either contact lenses or ultra thick glasses with power of greater than +10. Intraocular lens implants are one of the miracles of modern medicine. They are absolutely necessary, not luxuries fit only for a wealthy young person.

Multifocal vision: The new iol (intraocular lenses) are of 2 kinds, one allow you to see far and near (like a bifocal contact lens) and the other corrects for astigmatism. There is I believe one on the way that might do both but not yet on the market. Since cataract patients are senior the multifocal lens is a great advantage (but somewhat costly). ...Read more
Several Options: There are many lens choices for vision correction. Although the standard monofocal implant has stood the test of time (63 years to be exact), it has limited ability to provide you with glasses freedom. Toric implants correct astigmatism, while multifocal and accommodating lenses can provide distance and reading vision without glasses. Ask your eye surgeon about which may work best for you. ...Read more
Liquified!: The lens, and the cataract that is forming in the lens, is liquified by a process called phakoemulsification. That liquid is rinsed and drained out, so that the lens of the eye is gone. ...Read more
Premium IOL: Toric iols correct astigmatism. Multifocal and accommodative iols correct presbyopia. Multifocals provide better reading compared to accommodative iols but can result in a degradation in the overall quality of vision and produce side affects such as haloes around lights. Accommodative iols are monofocal so there is no degradation in the quality of vision but don't perform as well for near. ...Read more
Will need watching: If a cataract is removed in a baby, either a lens implant is placed during surgery, or contact lenses and/or glasses are prescribed afterwards. It is difficult to accurately predict the exact prescription needed in infants because their eyes may continue to grow, causing a change in their prescription. Regardless of which method is used, close follow-up is needed to avoid losing vision over time. ...Read more
Yes, that is routine: A cataract is the clouding of the eye's natural lens. Virtually all cataract surgery involves removing the cloudy lens and placing an artificial intra-ocular lens (iol) implant in its place. There are some newer more advanced iols that act like intraocular invisible bifocals to minimize need for postoperative glasses (multifocal iols) or to treat pre-exisiting astigmatism (toric iol). ...Read more
Possibly: I assume you mean intraocular lens implants. If the lenses have not been properly inserted, are multifocal, or if there is a residual refractive error, this may occur, although it is fairly uncommon. Another cause could be opacification of the membrane behind the implant, which can be cleared with the use of a laser. ...Read more
NO: No.Get a more detailed answer ›
There are 3 key options for cataract surgery: monofocal (give you ability to see 1 distance); multifocal (see multiple distances but risk of glare/halos); accommodative lenses (allow multiple distances; less risk of glare; but may not work as well for reading vision especially over time).

Yes: Contact lenses are like glasses in that they correct any refractive error. If a cataract is causing a refractive error (i.e. Myopia) without decreasing the sharpness much due to cloudiness, then contact lenses will help. Otherwise if the cataract is too cloudy, then contact lenses may not make the vision any better. ...Read more
Sometimes: It depends on the focusing of your eyes with your lens implants. Many patients now are able to achieve freedom from glasses or contact lenses with modern cataract surgery. Nearsightedness (myopia), farsightedness (hyperopia) and astigmatism can usually be corrected if desired. Some patients opt for implants that can correct presbyopia as well. ...Read more
Based on the amount:
If an Intra-ocular Lens Implant becomes displaced, the approach to repair (+/- surgery) depends on several factors.
1. Anterior Chamber vs. Posterior Chamber
2. Displaced (Subluxed) vs. Dislocated
3. Involvement of any other ocular structures
4. Level of the Intra-ocular Pressure
Bottom line: Please seek evaluation with your Ophthalmic Surgeon. ...Read more
Ask your doctor: You can research the lenses and then discuss your desires with your surgeon. Your surgeon should be able to describe the pros/cons of each lens and help you decide which is right for you. ...Read more
NO: Contact lens wearing will not slow the natural progression of cataracts! ...Read more
Promising: Exciting new technology......Shows promise but long term results are not yet known. ...Read more
Unlikely: When you have cataract surgery your doctor is removing the cloudy lens (the cataract) and implanting a clear, artificial lens. Our goal as surgeons is to give you the best vision possible. Talk to your doctor about the options of artificial lens implants available to you to meet your needs. Once a cataract is removed it does not return. ...Read more
Is it possible to have an allergy to acrylic cataract lenses they put in surgically to correct cataracts?
Probably not: "allergic reactions" do not occur to either silicone or acrylic intraocular lenses. Very rarely people have issues where the lenses need to be removed or exchanged for a different material (silicone for acrylic or vice-a-versa) but this is exceedingly rare. In these situations there are usually other factors in the eye contributing to the need for exchange and not an allergic reaction. ...Read more
