A newborn is found to have bilateral white pupillary reflexes. After ruling out retinoblastoma, lens examination reveals dense bilateral cataracts. Which inherited metabolic disorder should be evaluated first?
Answer: Galactosemia
Galactosemia is a critical metabolic cause of bilateral congenital cataracts that requires urgent dietary intervention to prevent systemic complications.
Which IOL material has the lowest rate of posterior capsule opacification (PCO)?
Answer: Hydrophobic acrylic
Hydrophobic acrylic IOLs have a sharp square edge design and material properties that create a strong barrier effect against lens epithelial cell migration, resulting in the lowest PCO rates.
A patient who underwent uneventful cataract surgery 3 weeks ago presents with decreased vision and a hypopyon. What is the most likely diagnosis?
Answer: Acute postoperative endophthalmitis
Acute postoperative endophthalmitis typically presents within 1-6 weeks after surgery with pain, decreased vision, and hypopyon.
In a patient with pseudoexfoliation syndrome undergoing cataract surgery, which intraoperative complication is the surgeon most likely to encounter?

What is the primary advantage of femtosecond laser-assisted cataract surgery (FLACS) compared to conventional phacoemulsification?
Answer: More precise and reproducible capsulotomy
Femtosecond laser creates a more precise, centered, and reproducible capsulotomy compared to manual continuous curvilinear capsulorhexis.
A 55-year-old patient presents with progressive painless vision loss and examination reveals a sunflower cataract. Which systemic condition is most commonly associated with this finding?
