Questions and Answers

What is the primary issue with monovision correction for presbyopia?

  • Adds over +1.50 tend to work better
  • It is ideal for patients with strongly dominant eyes
  • It adds a differential of +1.25 between eyes, leading to inhibition
  • It deteriorates binocular VA with adds beyond +1.25 (correct)

What is a characteristic of an ideal patient for multifocal correction?

  • Cylindrical correction
  • High prescription
  • Strongly dominant eye
  • Alternating SOT or XOT strabismus (correct)

What happens to binocular VA when adds exceed +1.25 in monovision correction?

  • It remains unaffected
  • It stays the same
  • It deteriorates (correct)
  • It improves significantly
