Summary

Younger age, better vision, and no eye comorbidity improve cataract surgery outcomes. Factors like gender and first-eye surgery also influence subjective visual function and satisfaction after the procedure.

Area of Science:

  • Ophthalmology
  • Patient-reported outcomes
  • Surgical outcomes

Background:

  • Cataract surgery is a common procedure aimed at restoring vision.
  • Identifying factors influencing patient benefit is crucial for optimizing surgical outcomes and patient satisfaction.

Purpose of the Study:

  • To identify preoperative and postoperative patient-related factors affecting the degree of benefit derived from cataract surgery.
  • To analyze how various patient characteristics influence subjective visual function and satisfaction post-surgery.

Main Methods:

  • A multicenter, prospective, cross-sectional study involving 14,817 patients undergoing cataract surgery in Sweden.
  • Utilized the Catquest-9SF questionnaire to assess subjective visual function pre- and postoperatively.
  • Employed multiple regression and logistic regression analyses to evaluate factors including age, visual acuity, comorbidities, and surgical details.

Main Results:

  • Younger age, better preoperative and postoperative corrected distance visual acuity (CDVA), and absence of ocular comorbidity were associated with greater improvement in subjective visual function.
  • Female gender and first-eye surgery correlated with higher improvement but lower overall postoperative subjective visual function.
  • Postoperative myopia ( -2 to 0 D) was linked to better outcomes compared to hyperopia; biometry prediction error sign influenced improvement but not final function.

Conclusions:

  • Patient-specific factors significantly influence the self-assessed benefit of cataract surgery.
  • Age, visual acuity, ocular health, surgical history (first vs. second eye), gender, and refractive outcomes are key determinants of visual function and satisfaction post-cataract surgery.
