Perioperative blurred vision affects over 4% of surgical patients. While most cases resolve within two months, some require vision correction adjustments, highlighting the need for monitoring post-operative visual changes.

Area of Science:

  • Ophthalmology
  • Surgical Patient Care

Background:

  • Perioperative visual changes are a concern for surgical patients.
  • Understanding the frequency and duration of these changes is crucial.

Purpose of the Study:

  • To determine the incidence of perioperative visual disturbances.
  • To describe the natural history of post-surgical vision changes.

Main Methods:

  • Prospective evaluation of visual acuity and accommodation in adult surgical patients.
  • Preoperative and postoperative assessments at 1 and 3 days.
  • Extended follow-up for persistent visual blurring.

Main Results:

  • 4.2% of patients reported new blurred vision lasting over 3 days.

  • 1% required new corrective lenses or prescription changes.
  • Most blurred vision resolved within 1-2 months; no significant risk factors identified.

    • Conclusions:

    • Blurred vision is a common, though often transient, post-operative complication.
    • A significant minority of patients with persistent blurring require eye care interventions.
    • The study highlights the importance of assessing visual disturbances after surgery.
