WHAT IS CATARACT?

 

Cataract, opacification of the lens, is one of the most common causes of loss of self-vision, with an estimated 16 million people worldwide affected. Cataract is the leading case of reversible visual impairment and blindness globally. Several risk factors have been identified in addition to increasing age — genetic composition, exposure to ultraviolet light, and diabetes. A cataract is a lens abnormality characterized by decreased transparency and increased cloudiness.

 

WHY EARLY CATARACT EXAMINATION IS IMPORTANT AROUND THE AGE OF 40?

 

· To determine if an individual is of high risk of cataract development due to health conditions such as

· diabetes

· To trace the family history as deemed necessary for proper consultation

· To efficiently know if the symptoms characterized are due to cataract or due to other persistent eye problems

· To discern and detect common associated problems developing at 40 years of age like angle glaucoma

WHAT IS THE IMPACT OF EARLY CATARACT SURGERY?

· Cataract surgery achieves excellent visual outcomes with low rates of complication To avoid unnecessary related complications during surgery related to hard cataract To preserve the eye's endothelial cells

· To improve the reading distance by using multifocal IOLs

INITIAL ASSESSMENT IS CRUCIAL FOR THE DETERMINATION OF PROPER IOL

· Examination of the eye of the patient with sophisticated imaging devices to give high-

· resolution images of the eye and help towards the extraction of accurate data to achieve the best result

· Data and the images help to form a treatment

· plan that is suitable for each eye according to its specificity

· Replacement of the lens with cataract with a new multi-focal lens "IOL" that helps the patient to eliminate dependence on glasses

WHAT ARE THE OUTCOMES OF A CATARACT SURGERY?

· improved and optimal vision for near,

· intermediate, and far distance improve visual function - acuity, color perception and contrast sensitivity

· ultimate satisfaction and improvement of quality of life
