Q1 · Senile Cataract
NEET PGEasyExplanation
Age-related (senile) cataract is the most common cause of cataract and the leading cause of reversible blindness worldwide. It causes gradual, painless loss of vision and glare, and is treated by surgical lens extraction with intraocular lens implantation.
Q2 · Cataract Surgery
NEET PGMediumExplanation
Phacoemulsification uses ultrasound to emulsify and aspirate the lens through a small incision, followed by foldable intraocular lens implantation. It is the standard modern technique, offering faster recovery than older methods.
Q3 · Congenital Cataract
HardExplanation
Congenital rubella causes cataracts, often with a 'pearly' nuclear appearance, along with deafness and cardiac defects. Congenital cataract needs early surgery to prevent stimulus-deprivation amblyopia. Galactosaemia is another metabolic cause.
Q4 · Leukocoria
HardExplanation
Leukocoria, a white pupillary reflex, in a child is a red flag for retinoblastoma, the most common intraocular malignancy of childhood, and must be urgently investigated. Congenital cataract and Coats disease are other causes.
Q5 · Lens Dislocation
MediumExplanation
In Marfan syndrome the lens typically dislocates upward, or superotemporally. In homocystinuria, by contrast, it dislocates downward. Recognising the direction helps distinguish these two connective-tissue disorders.
Q6 · Aphakia
MediumExplanation
Aphakia is the absence of the crystalline lens, for example after cataract extraction without an intraocular lens. It produces high hypermetropia. Pseudophakia refers to an eye with an implanted artificial lens.
Q7 · Avoidable Blindness
MediumExplanation
Cataract is the leading cause of reversible blindness globally, and cataract surgery is one of the most cost-effective interventions in medicine. Much of the world's blindness is avoidable, cataract and refractive error being major contributors.
Lens and Cataract sits within Ophthalmology, which carries the same syllabus in both exams. This set runs to 7 questions, each tagged Easy, Medium or Hard, 2 of them at Hard, and 2 drawn from previous-year papers.
Answer first, then read the explanation even on the ones you got right — the reasoning is where Lens and Cataract marks are actually won, and it is what separates a recalled fact from a question you can solve in a new form. Once the Easy set feels comfortable, filter to Hard to find the gaps Ophthalmology examiners keep returning to.
