What Are Cataracts?

Diabetic retinopathy is caused by blocked blood flow to the eye, causing ischemia or increased permeability of the blood vessels in the eye. Macular edema is caused by swelling in the eye due to the increased permeability, and both of these are common causes of vision loss of those with diabetes. Some factors that can be seen in the retina from a fundoscopic exam that can cause these issues (all of which were detected in our patient), are micro-aneurysms, intrarenal hemorrhages, and hard exudates. All three of these can disrupt the blood-retinal barrier, causing issues with blood flow and swelling. Additionally, lipids and proteins both play important roles in the eye, and if there is improper breakdown of these molecules, they can make deposits in the outer layer eye. The more deposits (hard exudates) a patient has, the larger affect it can have on their vision.

The damage caused by glaucoma can't be reversed. But treatment and regular checkups can help slow or prevent vision loss. The goal of glaucoma treatment is to lower pressure in your eye. Depending on your situation, your options may include eye drops, laser treatment or surgery.

It’s usually a buildup of pressure inside your eye. Glaucoma tends to be inherited and may not show up until later in life. The increase pressure, called intraocular pressure, can damage the optic nerve, which transmits images to your brain. If the damage continues, glaucoma can lead to permanent vision loss. Without treatment, glaucoma can cause total permanent blindness within a few years. Most people with glaucoma have no early symptoms or pain. People need to see a eye doctor regularly so he/she can diagnose and treat glaucoma, before long-term visual loss

Post-cataract endophthalmitis is a rare but serious complication.1 Recent studies show a rate of postoperative endophthalmitis after cataract surgery of 0.04% to 0.29%.2-4 However, it remains the most important concern for surgeons, because it can have devastating consequences on vision.5 It is recently reported that 9% of patients with endophthalmitis have a poor ocular prognosis (visual acuity <20/100).6

Defects in the shape of the lens, or inadequate filling of the vitreous humor, can result in inadequate vision. Age and disease also play their part in reducing human vision. Thus, perfect vision at birth may require correction as early as grade school, and will almost certainly require correction by the age of retirement.

Individuals are risk for cataracts are those affected with a disease such as diabetes, smoking or alcohol use, or prolonged sunlight exposure. Symptoms are cloudy or blurry vision, fading color, glare, poor night vision, double image in one eye, and frequent eyeglasses prescription changes. Treatment depends upon when cataract is detected. Early detection can be improved with eyeglasses, better lighting, glare sunglasses, or magnifying. If this does not work surgery is used. The lens is replaced with an artificial

A cataract is a obscuring of the lens in the eye that affects the power of vision. Mostly cataract are associated with ageing. Cataracts are very common in older people. It can arise either in both eyes and one eye. It is not communicative, hence it cannot be transmitted from one eye to other.

If you still have vision problems after surgery, your doctor may follow up with a LASIK procedure after your eyes have healed.

There are different surgical options to address residual refractive errors that frequently occur after corneal transplantation. None of them appear as a perfect option and corneal surgeons should tailor a specific plan for each patient individually. Many factors affect the surgeon's choice of the best surgical option including the ocular condition, patient requirements, surgeon skills and the available technology. The ocular condition as well as the type of refractive error and its degree remain the most important factors in the choice of the refractive intervention.

If you notice any changes in your vision, it is important that you make an appointment for an eye exam as soon as possible. You should also see your doctor right away if you develop sudden changes in your vision, such as flashes of light or double vision, sudden headaches or sudden eye pain. If your doctor recommends cataract surgery, it is up to you and your doctor to decide when the surgery may be right for you. Although cataracts do not harm your eyes, they can worsen, especially in people with diabetes. Delaying cataract surgery will not affect how well your vision recovers after the surgery and if you choose not to have cataract surgery, your eye doctor will typically recommend periodic follow-up exams to make sure the cataract isn’t

Cataract is known as a build-up of protein clouding the eye lens which distorts or blocks the light entering the eye. When new lens cells form on the outside of the lens, all older cells are compacted into the center of the lens which therefore causes Cataract. Cataract can be partial or complete, stationary or progressive, hard or soft. There are 3 types of cataract known as Nuclear Sclerosis, Cortical Cataracts, Posterior Subcapsular cataracts. But the most common type of cataract is Nuclear sclerosis. Which involves in the central part of the lens. Sclerotic is due to the condensation of the lens nucleus which deposition of brown pigment within the lens. Cataract can be first presenting during birth or early childhood which is a result of hereditary enzymes defect. At first cataract can be very undetectable, but later it will grow and you will have exhibiting

In this article, “Three surgeon-innovators share their LenSx[R] Laser Pearls". Dr. LaBorwit et. al restates "Rudimentary cataract surgery is centuries old, primarily taking the form of couching, then evolving with early attempts with intraocular lens (IOL) implantation starting in the mid-1700s"(pS1). It discusses how the technical advances of the last few years have propelled surgical procedures into a bright new era. It provides practices that have embraced this new approach to cataract surgery and the errors how best to incorporate it by laser technology into their patient flows. This source is a benefit for my source because it contains how laser eyes optimized both their technique and the reproduction of their outcomes. It gives agreeable

Patients can resume normal activity such as reading, walking, eating, and watching television the evening of surgery.The eye may be patched, depending upon whether anesthesia was local or topical. The eye is typically examined on the first post-operative day. Many surgeons allow resumption of driving at the level immediately prior to surgery at this time, as long as continued patching is not required. Sutures are removed at 6 to 12 weeks if there is suture-induced astigmatism. (Jacobs, 2015)

Cataract is the leading cause of blindness in the world [1] . Cataract is a clouding of the lens in the eye that affects vision [2]. Cataract can occur in either or both eyes. It cannot spread from one eye to the other [2] .Cataracts generally form very slowly. Signs and symptoms of a cataract may include:

If you have cataracts, you may be able to put up with cloudy vision for a few years, but eventually, you'll probably need surgery to remove the cataracts and improve your vision. That's because cataracts continue to grow and your vision gets progressively worse over the years. At some point, your vision may become so impaired you have difficulty driving at night, or you may increase your risk of falling. Cataract surgery is very common and it is a relatively safe procedure. It is even being done with lasers now, which lowers the risks further. Here are a few things to know about having your cataracts removed with a laser.
