What is Aphakia?
Eye contains a limpid transparent biconvex lens system which focuses the ikon on the retina . It is this lense which offers visual modality of the world around us . Aphakia is a aesculapian circumstance where the lens is removed from an heart due to cataract procedure or during an injury . A person with aphakia has problems in focusing on the aim and has difficultness in see . ( Aphakia means a = without ; phakos= electron lens ) . Aphakia is primarily observed in grownup after the age of 40 years and is seldom seen in the newborns .
Characteristics of Aphakia
Causes and Risk Factors of Aphakia
The grounds and risk factors for aphakia include :
Cataract:
The presence of cataract urinate the lens cloudy due to which it can not refract luminosity and the moved person can not see . The lens becomes milklike in appearance due to clippety-clop of the protein because of the increased age . In uncommon case , babies are born with cataract which is either a genetic defect or caused due to disease such aschickenpox . Such lens is removed surgically resulting in aphakia . Aphakia due to cataract is most plebeian .
Congenital Aphakia:
It is a very rare term where babies are give birth without lens in their heart . This is called as congential aphakia and is of two types : basal aphakia and lower-ranking aphakia .
Primary aphakia is of severe form where babies with developmental problems or familial mutation are born without lens . While lowly aphakia is of less stern form where , babies have lens however it gets absorb or detached before birthing . This character of aphakia also lead due to transmission with rubella computer virus .
Optical Aphakia:
Posterior disruption of lens in vitreous causes optical aphakia
Aphakia due to Injury:
If injury or trauma come about to the face , then they can damage lens or cause it to get detach and push it inside the optic .
immersion of Lens Matter pass off seldom after hurt in children
Heredity Causes of Aphakia:
There are few heritable disorders which cause dislocation of lens :
Diagnosis of Aphakia
An ophthalmologist examines the eye for presence of cataract in the heart lens . The doctor also examines the iris , cornea , fundus and retina . The distance , near visual sense and deflection are determined .
The doctor looks for different signs such as :
For a person with no lens , it further corroborate aphakia .
Treatment of Aphakia
The absence of the lens makes the vision farsighted . Although , spectacle and contact lens can be used , they have a number of disadvantages . Hence they are not opt . The handling method acting include :
Complications of Aphakia
Person suffer from aphakia should take treatment to avoid these complications :
Conclusion
Aphakia is an ophthalmic problem which needs to be treat . Opting for late method such as habit of stilted lens and refractile operating room will ameliorate the liveliness of an aphakia affected role .
