Eye Diseases

Learn more about the definitions and symptoms of common eye disorders. Click on a tab on the left below.



A Cataract is a "clouding" of the lens in your eye. As light passes through the cataractous lens, it is diffused or scattered. The result is blurred or defocused vision.


Clouded, blurred or dim vision, difficulty with vision at night, sensitivity to light and glare, seeing "halos" around lights, fading or yellowing of colors, double vision in single eye, frequent changes in eyeglass or contact lens prescription.


If the symptoms of early cataract are not improved with new eyeglasses, anti-glare sunglasses or magnifying lenses, surgery is needed. Surgery involves removing the cloudy lens and replacing it with an artificial lens.

Diabetic Retinopathy

Diabetic Retinopathy

Diabetic Retinopathy is a diabetes complication that affects eyes. It's caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye.


At first, diabetic retinopathy may cause no symptoms. Symptoms include spots or dark strings floating in your vision (floaters), blurred vision, fluctuating vision, impaired color vision, dark or empty areas in your vision or vision loss.


There is no cure for diabetic retinopathy, but laser treatment is usually very effective at preventing vision loss if it is done before the retina has been severely damaged. Surgical removal of the vitreous gel may also help improve vision.



Pressure buildup in the eye is proven to be a major risk factor for Glaucoma. If Glaucoma is left untreated it may lead to blindness.


Blurred vision, appearance of rainbow-colored circles, severe eye and head pain, nausea, vomiting or sudden sight loss. Regular eye exams can help detect glaucoma in its early stages before irreversible damage occurs.


Glaucoma can be treated with eye drops, pills, laser surgery, traditional surgery or a combination of these methods. The goal of any treatment is to prevent loss of vision, as vision loss from glaucoma is irreversible.

Other Eye Disorders

Difference between Presbyopia and Pterygium

A Pterygium is a triangular growth of abnormal tissue that invades the cornea. Presbyopia is long-sightedness caused by loss of elasticity of the lens of the eye.

Retinal Detachment

Retinal Detachment is a disorder of the eye in which the retina separates from the layer underneath. Without treatment permanent loss of vision may occur. Can be treated with laser surgery.

Macular Degeneration

Macular Degeneration is the leading cause of severe vision loss in people over age 60. It occurs when the small central portion of the retina, known as the macula, deteriorates. Can be treated with laser surgery.

What is a Intraocular Lens

What is an Intraocular Lens?

All currently available artificial lenses filter UV light, but the ACRYSOF® Natural IOL filters both UV and blue light. Read more about Intraocular Lenses.

Filters Blue Light

The ACRYSOF® Natural lens is transparent yellow, the color necessary to filter blue light. The patented yellow tint does not alter the natural colors of the things you see or the quality of your vision.

Stable & Centered

The ACRYSOF® Natural IOL is designed to conform to the natural shape of the lens capsule. This helps it stay stable and centered in the eye. It enhances the benefits of advanced cataract surgery by filtering out blue light.

Cataract Surgery

In cataract surgery, the lens inside your eye that has become cloudy is removed and replaced with an artificial lens to restore clear vision. The procedure typically does not require an overnight stay in a hospital or other care facility.

Diabetic Retinopathy

The major purpose of laser surgery is to prevent further visual loss and doesn’t necessarily improve vision. In advanced retinopathy the retina can be re-attached by doing a vitrectomy and by removing the scar tissue and new blood vessels.

Glaucoma Treatment

There is no cure for glaucoma, but can be treated effectively when caught early. The primary effect of most glaucoma medications is lowering IOP. This has been proven to be an effective way to help prevent or slow down vision loss.

Laser (excimer) Refractive Surgery

Refractive eye surgery improves the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses. Surgical approach is not considered if patients are comfortable with their glasses or their contact lenses.

Read More
Pterygium Treatment

Eye drops such as preservative free lubricants, vasoconstrictors and mild cortico steroids can relive the symptoms. The pterygium is removed surgically and the method depends on the surgeon doing the operation.

Read More
LASIK Surgery

LASIK is considered safe and effective for patients with low to high myopia (up to +-10 diopter of shortsightedness), with or without astigmatism and low to moderate hyperopia (up to +- 3 diopter of farsightedness).
