ETIOLOGY OF ANISOMETROPIA
The facts we need to know about anisometropia, that anisometropia a condition that occurs when the eyes have varryring refractive powers, which can cause eyes to focus unevenly. This condition…
BINOCULAR VISION AND APHAKIA
Binocular vision is the ability of both eyes to focus on a single object to give a clear three dimensional image to the brain. That is, we gain a single…
Treatment of APHAKIA
What is aphakia? Aphakia (a, privative, pakos, lens) means absence of crystalline lens from the patellar fossa of the eye. In the majority of the cases the lens has been…
Etiological Types of Aphakia
Aphakia = 'A+phakia' 'A' means absence, and 'Phakic' refers to a person with an intact natural lens. So Aphakia means absence of the crystalline lens in it’s normal anatomical position…
Optics of Aphakia
Humans have the Ability to see UV light, but it is filtered by the eye’s lens. People who have surgery to remove the lens can see UV light. The condition…
TREATMENT OF ASTIGMATISM
Introduction: Astigmatism, as we know it, is ametropia created by meridional variation in refractive power of the eye. Curiously, it is one of the most difficult areas of refraction &…
