Occipital Neuralgia Occipital neuralgia is a headache syndrome that can be either primary or secondary. Secondary headaches are associated with an underlying disease that may include tumor, trauma, infection, systemic disease or hemorrhage.

Intraocular lens Intraocular lens (IOL) is a lens implanted in the eye used to treat cataracts or myopia. The most common type of IOL is the pseudophakic IOL. These are implanted during cataract surgery, after the cloudy crystalline lens (otherwise known as a cataract) has been removed.

Intraocular melanoma Intraocular melanoma is a cancer of the pigment-producing cells (melanocytes) in the middle layer of the eye, called the uveal tract.

Cataract surgery Artificial intraocular lenses are used to replace the eye's natural lens that is removed during cataract surgery. These lenses have been increasing in popularity since the 1960s, but it was not until 1981 that the first U.S. Food and Drug Administration (FDA) approval for this type of product was issued.

Cataracts Toric IOL. Many cataract patients suffer from astigmatism and have required glasses or contact lenses to drive or read for much of their adult lives. Toric lens implants correct for astigmatism and are placed in the patient’s eye during routine cataract surgery just as the other intraocular lenses used here at The Eye Care Institute.

- As these cells grow, the thin, cellophane-like membrane becomes thick and cloudy like wax paper. Since this blocks and blurs light similar to a cataract, it is often called a secondary cataract. Other more technical terms for this condition are posterior capsule opacity or capsule opacity. symptoms Treatment is only necessary if the cloudy membrane affects a person’s vision and lifestyle.

Late congenital syphilitic oculopathy Late congenital syphilitic oculopathy. Late congenital syphilitic oculopathy is a disease of the eye, a manifestation of late congenital syphilis. It can appear as: Interstitial keratitis – this commonly appears between ages 6 and 12. Symptoms include lacrimation and photophobia.

Review ArticleIndications for a systemic work-up in glaucoma Primary glaucomas, by definition, are isolated to the eye without an identifiable ocular or systemic cause and do not require systemic evaluation. However, secondary glaucomas have an underlying cause, which may or may not require a systemic work-up.

- In addition to the loss of optic nerve fibers, primary open-angle glaucoma is characterized by open anterior chamber angles, visual field abnormalities, and intraocular pressure that is too high for the continued health of the eye.

ICL implantation Without glasses, light from objects further than 1/8th of a metre away from the eye is focussed in front of the retina, forming a blurred image. The ICL for high myopia (-8.00D and above) is a negative lens which acts to neutralise the excessive focussing power of the eye allowing clear vision in the distance.

- Intraocular pressure: The pressure created by the continual renewal of fluids within the eye. The intraocular pressure is increased in glaucoma. In acute angle-closure glaucoma, the intraocular pressure rises because the canal into which the fluid in the front part of the eye normally drains is suddenly blocked.ntraocular pressure: The pressure created by the continual renewal of fluids within the eye.

Acute Closed-Angle Glaucoma Acute closed-angle acute glaucoma is the result of sudden and severe increased intraocular pressure due to a blockage of fluid drainage by the iris, the colored part of the eye. Symptoms of acute closed-angle acute closed-angle glaucoma occur suddenly and can rapidly lead to blindness if not treated emergently.

- An intraocular lens is like a contact lens that will be permanently implanted into your eye behind your iris (the blue, green or brown part of the eye). It does not need to be removed or cleaned, and will greatly improve your vision.n intraocular lens (IOL) is a precisely engineered artificial lens that is used to replace the cloudy (cataractous) lens.

- Light rays from near objects diverge as they enter the eye. The AcrySof ® IQ ReSTOR ® Multifocal Toric IOL uses its central apodized diffractive region and +3.0 D correction to focus these rays into a clear image on the retina.

Cataract surgery Intraocular lens implantation: After the removal of the cataract, an intraocular lens (IOL) is usually implanted into the eye, either through a small incision (1.8 mm to 2.8 mm) using a foldable IOL, or through an enlarged incision, using a PMMA (polymethylmethacrylate) lens.

Multifocal Intraocular Lens Implants - Premium IOL's Multifocal Intraocular Lens Implants - Premium IOL's. With age, the natural lens inside the eye becomes less clear. This change leads to a disease/condition known as a cataract*. Cataracts are the leading cause of reversible vision loss in this country. Fortunately, in most cases the cataract is removable and vision can be restored with an intraocular lens (IOL)*.

- Capsular thickening. The capsule is the outer bag of the natural lens that is left behind during surgery to hold the artificial lens or implant. Over time, in some patients, this outer shell becomes cloudy, a condition known as capsular thickening or secondary cataract.The patient will notice vision becoming blurred – just like it did with the original cataract.apsular opacification (secondary cataract) is treated using a YAG laser and this is a brief and painless out-patient procedure. The pupil will be dilated at the time and the laser makes a new clear pathway in the area of the pupil, allowing light to reach the back of the eye.

Overview Nearly everyone who has cataract surgery will be given an artificial lens called an intraocular lens (IOL). These lenses improve your vision by focusing light on the back of your eye. You won't be able to see or feel the lens. It requires no care and becomes a permanent part of your eye.

Overview When placing a primary buckle, this is performed with indirect ophthalmoscopy via the aid of a condensing lens, typically a 20- or 28-D lens. The use of scleral indentation to bring the peripheral retina into view is necessary in order to achieve full visualization.

- With primary glaucoma, both eyes are rarely effected equally or at the same time. The disease usually occurs in one eye months or even years before it affects the second one. Secondary Glaucoma: Secondary glaucoma means that the disease is secondary to, or caused by, another condition. A common example is a penetrating wound to the eye. This often causes an inflammation and the fluid may become too thick to flow out through the drainage pores or it might cause scar tissue to form with the drainage angle, itself, closing.

- 1.57 mid index single vision lenses means that the lens is thinner than standard plastic lenses. It is not the thinnest possible, nor is it impact resistant like Trivex 1.53 m … id index lenses, or polycarbonate. It will be thinner than either of those materials. Single vision means that there is one range of vision.

- 01, 2016. Before intraocular lenses (IOLs) were developed, people had to wear very thick eyeglasses or special contact lenses to be able to see after cataract surgery. Now, with cataract lens replacement, several types of IOL implants are available to help people enjoy improved vision.

Secondary posterior chamber intraocular lens implantation in Fuchsâ heterochromic uveitis Secondary posterior chamber intraocular lens implantation in Fuchs’ heterochromic uveitis. In almost all patients with uveitis requiring cataract surgery, phakoemulsification with intraocular lens (IOL) implantation is the procedure of choice. The need for stringent peri-operative control of uveitis is well-documented.
