Fear of Falling and Vision-Related Quality of Life of Patients Before and After Cataract Surgery, Evaluation of Postoperative Care Compliance: A Prospective Longitudinal Study
Although cataract surgery is an effective treatment method for improving visual function, it is important to evaluate the quality of life, daily living activities, independence level and psychosocial well-being of patients in the postoperative period.
Changes in visual function can affect individuals' ability to live their daily lives, their perception of the risk of falling, and their adaptation to post-treatment care processes.
For this reason, the recovery process after cataract surgery should be evaluated not only with clinical results, but also with patient-centered outcome criteria.
The aim of this research is to investigate the preoperative and postoperative period in patients undergoing cataract surgery 1. and 3.
The aim is to prospectively evaluate changes in care compliance, fear of falling, and vision-related quality of life during monthly follow-ups.

Conditions
Detailed Description
Cataract surgery is one of the most commonly performed and most successful surgical procedures worldwide, and it is performed on more than 20 million individuals every year (Lundström et al., 2021).
Age-related cataract is a condition that develops as a result of the loss of transparency of the lens of the eye, especially in the older age group, and is considered one of the leading causes of vision loss on a global scale (World Health Organization [WHO], 2025).
Although cataract surgery is performed in order to restore visual function and increase an individual's visual capacity, it is stated that surgical success should not be evaluated solely by clinical indicators such as visual acuity; its effects on an individual's daily life activities, level of independence, and visual-related quality of life should also be taken into account.
Current studies have shown that cataract surgery provides significant improvement in vision-related quality of life and positively affects the functional status of individuals

Cataract Surgery Group
Description: A single cohort of patients undergoing cataract surgery will be followed prospectively from the preoperative period to 1 and 3 months after surgery. No research intervention will be administered. Participants undergoing cataract surgery will be followed prospectively from the preoperative period to 1 and 3 months after surgery. Fear of falling, vision-related quality of life, and postoperative care adherence will be assessed at the predefined follow-up time points. No additional intervention will be administered by the researchers. |
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Outcome Measure: Change in Vision-Related Quality of Life
Time Frame: Baseline (preoperative) to 3 months after cataract surgery
|
Change in vision-related quality of life from the preoperative assessment to 3 months after cataract surgery, measured using the National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25).
Higher scores indicate better vision-related quality of life.

Primary Outcome Measure: Vision-related quality of life measured by the NEI-VFQ-25
Time Frame: Baseline (preoperative), 1 month, and 3 months after cataract surgery
|
Change in vision-related quality of life from the preoperative assessment to 1 month and 3 months after cataract surgery, measured using the National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25).
|
Baseline (preoperative), 1 month, and 3 months after cataract surgery

Measure Description |
Time Frame |
|---|---|---|
|
Outcome Measure: Fear of falling measured by the Falls Efficacy Scale-International (FES-I)
Time Frame: Time Frame: Baseline (preoperative) and 3 months after cataract surgery
|
Fear of falling will be assessed before and 3 months after cataract surgery.
|
Time Frame: Baseline (preoperative) and 3 months after cataract surgery
|
|
Outcome Measure: Postoperative care adherence measured by the researcher-developed Cataract Surgery Postoperative Care Adherence Form
Time Frame: Time Frame: 1 month and 3 months after cataract surgery
|
Postoperative adherence to recommended eye care and follow-up practices will be assessed at 1 and 3 months after cataract surgery.
