Phacoemulsification and intraocular lens (IOL) implantation improved vision for most patients. However, some older individuals with lower satisfaction reported no functional visual improvement, suggesting a need for better expectation management.

Area of Science:

  • Ophthalmology
  • Surgical Outcomes
  • Patient-Reported Outcomes

Background:

  • Cataract surgery, specifically phacoemulsification with intraocular lens (IOL) implantation, is a common procedure to restore vision.
  • Assessing subjective functional visual improvement is crucial for understanding the real-world impact of cataract surgery.
  • Identifying factors associated with suboptimal outcomes can help refine surgical counseling and patient selection.

Purpose of the Study:

  • To evaluate subjective functional visual improvement following phacoemulsification and IOL implantation.
  • To identify patient characteristics and treatment features linked to a lack of functional visual improvement.

Main Methods:

  • Retrospective review of 106 eyes from 102 patients who completed ASCRS Cataract Data Collection Forms preoperatively and 1 month postoperatively.

  • Analysis of patient characteristics and treatment features using ANOVA, Wilcoxon rank sum, and Fisher exact tests.
  • Single surgeon performed all procedures, ensuring consistency in surgical technique.

    • Main Results:

    • All patients showed improved visual acuity post-surgery, but 14% reported no functional improvement or a decrease in visual function.
    • No significant differences were found in visual acuity, refractive error, preoperative symptoms, satisfaction, daily functioning, or comorbidities between groups.
    • Patients reporting no functional improvement tended to be older and expressed lower satisfaction with quality of life and medical care.

    Conclusions:

    • Phacoemulsification and IOL implantation generally lead to improved self-reported visual function.
    • Older patients with lower life satisfaction may not experience functional visual improvement despite enhanced visual acuity.
    • Extended preoperative discussions regarding postoperative expectations are recommended for these patients to manage expectations effectively.
