2) Cylindrical lenses are used in:
- A. Astigmatism
- B. Myopia
- C. Hypermetropia
- D. Presbyopia

3) All of the following lead to the formation of complicated cataract, except:
- A. Pigmentary retinal dystrophy
- B. Progressive hypermetropia
- C. Progressive myopia
- D. Iridocyclitis
Click “Show more” to see the answer and explanation.
Correct Answer: B.
Explanation:
Complicated cataracts are secondary cataracts that occur due to other ocular diseases or systemic conditions. Common causes include pigmentary retinal dystrophy, progressive myopia, and iridocyclitis, as these involve structural or metabolic changes in the eye. Progressive hypermetropia does not lead to such changes, making it an exception.
