Question

- Abnormal lens fibers migrate posteriorly from the equator, form an opacity in the region of the central posterior capsule.

- Cataracts often present in the first few months of life, and if visually significant at an early age, can lead to amblyopia.
- Most posterior polar cataracts are stationary, but can progress in severity over time.
- More difficult to remove surgically because the posterior capsule can be thinned. What eye condition is being described by the provided information?

A) Zonular cataract
B) Polychromatic cataract
C) Morgagnian cataract
D) Anterior subcapsular cataract
E) Posterior polar cataract

Answer 1

The condition described is Posterior polar cataract, marked by opacity in the lens, potential amblyopia risk, and surgical challenges. Parallel laser light is needed in eye surgery due to the eye's natural focusing mechanism. A converging lens is used to correct hyperopia, where images would otherwise focus behind the retina.

Step-by-step explanation:

The eye condition being described by the provided information is E) Posterior polar cataract. A cataract is cloudiness in the lens of the eye. When discussing cataract surgery and its considerations, it is worth noting that this cloudiness can cause light to be dispersed or diffused, leading to vision impairment. When repairing a tear in the retina with laser surgery, the incoming laser light must be parallel to ensure accurate focus on the targeted area. This precision is crucial because a normal-vision eye converges the incoming parallel rays onto the retina for clear vision. If the condition prescribed causes hyperopia, images are focused behind the retina, and a converging lens would be needed to correct the vision by moving the focus onto the retina.
