WHAT ARE CATARACTS?

Cataracts are a common eye condition characterized by the clouding of the eye's natural lens, leading to blurred vision and diminished visual clarity. The lens, primarily responsible for focusing light onto the retina, becomes progressively opaque over time, causing vision impairment. 
 

Causes of Cataracts: 

 

Age-related changes are the most common cause of cataracts, other factors can also contribute to their development. 

• Genetic predisposing

• Prolonged exposure to ultraviolet (UV) radiation

• Diabetes

• Trauma to the eye

• Eye inflammation

 

Symptoms:

 

Cataracts can manifest gradually, and the symptoms may vary from person to person. some common symptoms include:

• Blurry or cloudy vision

• Increased sensitivity to glare, particularly at night

• Difficulty seeing in low light conditions

• Fading of vibrant colors

• Double vision in one eye

• Frequently needing stronger prescription eyeglasses or contact lenses

​

Diagnosis:

​

An eye examination by an ophthalmologist is essential for diagnosing cataracts. The doctor will assess your vision, examine the lens, and evaluate your eye health to determine the presence and severity of cataracts. 

​

Fortunately, cataract can be effectively treated, restoring clear vision and enhancing your quality of life. The decision on when to treat cataracts depends on how much they impact your daily activities. 

​

Cataract surgery is a safe and common procedure, during which the cloudy lens is removed and replaced with an artificial intraocular lens (IOL). This outpatient surgery typically results in significant improvement in vision. 

​

Types of Intraocular Lens (IOLs):

​

Intraocular lens are made of silicone, acrylic or other plastic compositions. 

​

All intraocular lenses come in Toric and Non-Toric type. Toric lens correct astigmatism which is a refractive error caused by an uneven curve in your cornea or lens. The Toric lens is designed to correct that refractive error. 

​

      1.  Monofocal IOLs:  Most traditional type and provide clear vision at one fixed distance. You will need glasses to focus on                 close objects. ​​​

            a. Single vison Non-Toric (standard): MSP covered.

               Help you see objects in the distance like street signs, stage performances, and sporting events. 

​

            b. Single vison Toric: Not MSP covered.

               Provide clear distance vision with astigmatism correction. 

​

     2.  Extended Depth of Focus: Designed for distance and improved intermediate vison to make everyday tasks easier. You will             need glasses to see closer. Helps you see objects in the distance like traffic lights, dinner plate, stage performance and                 sporting events. 

​

     3.  Multifocal IOLs: They are designed to provide vision at multiple distances, reducing the dependence on glasses after                     surgery. 

        If you have underlying eye diseases, you may not be a candidate for this lens.
