Journal of cataract and refractive surgery·2017

Cataract surgery outcomes remain stable long-term for most patients. Age-related macular degeneration and glaucoma are primary causes of visual decline 5 years post-surgery.

Area of Science:

  • Ophthalmology
  • Public Health

Background:

  • Cataract surgery is a common procedure to restore vision.
  • Long-term visual function outcomes after cataract surgery require further investigation.

Purpose of the Study:

  • To assess long-term visual function 5 years after cataract surgery.
  • To compare preoperative, postoperative, and 5-year visual function data.

Main Methods:

  • Prospective longitudinal population-based cohort study.
  • 810 patients undergoing cataract surgery were initially included.
  • Visual acuity and Visual Function-14 (VF-14) questionnaire data were collected preoperatively, postoperatively, and at 5-year follow-up.

Main Results:

  • Median VF-14 score decreased slightly from 100 post-surgery to 96.7 at 5 years (P = .001).

  • At 5 years, 46% had stable or improved visual acuity; 37% lost >0.1 logMAR unit.
  • Age-related macular degeneration (ARMD) and glaucoma were the main causes for visual decline.

    • Conclusions:

    • Most patients maintain stable subjective and objective visual function 5 years after cataract surgery.
    • Comorbidities, particularly ARMD, are the most common reasons for visual deterioration.
    • Age and comorbidities independently predict 5-year VF-14 scores.
