Aphakia is a condition in which you’re missing the lens of one or both of your eyes. You can be born that way or lose the lens due to an injury. Or your doctor might remove it during an operation for cataracts. When you have aphakia, it’s hard to see things clearly with the affected eye.
What is Pseudophakia of the eye?
Pseudophakia is a Latin word for false lens. We use this term after placing an artificial lens into the eye. Also known as intraocular IOL, lens implants, or fake eye lenses, this procedure can significantly improve vision after removing cataracts and replacing them with a new lens.
How do they fix cataracts?
During cataract surgery, the clouded lens is removed, and a clear artificial lens is usually implanted. In some cases, however, a cataract may be removed without implanting an artificial lens. Surgical methods used to remove cataracts include: Using an ultrasound probe to break up the lens for removal.
What are the signs of aphakia?
What are the symptoms of aphakia?
- blurry vision.
- trouble focusing on objects.
- changes in color vision, which involves colors appearing faded.
- trouble focusing on an object as your distance from it changes.
- farsightedness, or trouble seeing things up close.
What is the astigmatism?
Overview. Astigmatism (uh-STIG-muh-tiz-um) is a common and generally treatable imperfection in the curvature of the eye that causes blurred distance and near vision. Astigmatism occurs when either the front surface of the eye (cornea) or the lens inside the eye has mismatched curves.
What is the presbyopia?
Presbyopia is the gradual loss of your eyes’ ability to focus on nearby objects. It’s a natural, often annoying part of aging. Presbyopia usually becomes noticeable in your early to mid-40s and continues to worsen until around age 65.

Nonsteroidal anti-inflammatory agents and corticosteroids in various forms can be used, but each type of treatment lacks satisfactory success.
What causes Pseudophakia?
Pseudophakia often occurs during cataract surgery. A cataract causes clouding or blurring of the lens in a person’s eye and is a common condition often related to aging.
What is Aphakia and Pseudophakia?
Aphakia can be corrected by wearing glasses, contact lenses, artificial lens implantation, or refractive corneal surgeries. Eye with artificial lenses are described as pseudophakic.

Why is vitrectomy performed?
Vitrectomy procedures are often done to allow surgeons access to the back of the eye, during operations for retinal conditions. It is also commonly done to drain vitreous fluid that has become cloudy or bloody, or filled with floaters or clumps of tissue.
What happens when the eye lens is removed?
By Tina D. Turner, M.D. Once the natural lens in the eye has been removed, the eye loses its ability to focus light and images clearly on to the retina, the light-sensitive tissue that lines the inside surface of the eye.
Can you see without eye lens?
No, the eye cannot focus properly without a lens. Thick eyeglasses, a contact lens or an intraocular lens must be substituted to restore the eye’s focusing power.
What happens when you have astigmatism?
With astigmatism, the lens of the eye or the cornea, which is the front surface of the eye, has an irregular curve. This can change the way light passes, or refracts, to your retina. This causes blurry, fuzzy, or distorted vision.
Can astigmatism go away naturally?
Can astigmatism go away on its own? Astigmatism will not go away on its own. It will either stay the same or get worse with age. While this reality can seem daunting, the good news is that it can be easily corrected.
Do I need glasses for astigmatism?
Glasses or contacts can correct almost all cases of astigmatism. But if you have only a slight astigmatism and no other vision problems, you may not need them. If you have a common level of astigmatism, you’ll probably have corrective lenses, like glasses or contacts, or surgery.
What does Dr Prince examine the eye with?
The slit lamp examination, in conjunction with pupil dilation, allows your eye doctor to look at the structures of the eye.
Is presbyopia farsighted or nearsighted?
Being farsighted is one of the risk factors for getting premature presbyopia. Farsightedness (hyperopia) is often confused with presbyopia, but the two are different. Presbyopia occurs when the eye’s lens loses flexibility. Farsightedness occurs when the eyeball is too short.
How do you fix presbyopia?

What is Pseudophakia with PCO?
Abstract. Posterior capsule opacification (PCO) is a late complication after the cataract surgery, currently occurring most often. The epithelial cells which migrate to the surface of the posterior capsule participate in the mechanism of PCO formation.
What causes a Pinguecula?
A pinguecula is caused by changes in your conjunctiva tissue. These changes have been linked to irritation caused by sun exposure, dust, and wind, and are more common as we age. These bumps or growths may contain a combination of protein, fat, or calcium, or a combination of the three.
What is it called when your eye turns out?

The refractive lensectomy procedure is performed on an outpatient basis. Only one eye will be treated at a time. After the eye is completely numbed with topical or local anesthesia, the eye’s natural lens will be gently vacuumed out through a tiny incision, less than one eighth of an inch wide.
What happens if lens moves after cataract surgery?
Displacement of the intraocular lens causes changes to vision and, if it falls into the vitreous cavity, it can produce traction due to the eye’s own movement, resulting in retinal detachment and/or vitreous haemorrhage.
How is Pseudophakia different?
