The Effect of Periodic Intensive Education on Surgical Outcomes in Cataract Surgery Patients

The goal of this clinical trial is to learn whether periodic education can improve recovery outcomes in older adults undergoing cataract surgery. The main questions it aims to answer are:

Does periodic education improve patients' adherence to prescribed eye medications after cataract surgery?

Does periodic education reduce postoperative complications and improve vision-related quality of life?

Researchers will compare patients who receive structured periodic education in addition to routine postoperative care with those who receive routine postoperative care alone to see if education improves recovery outcomes.

Participants will:

Receive either routine postoperative care or structured periodic education about correct eye drop use and self-care practices

Attend follow-up visits during the first three weeks after surgery

Complete questionnaires to assess medication adherence and vision-related quality of life

About this study

Detailed Description:

Cataract surgery is one of the most frequently performed surgical procedures among older adults and is generally associated with favorable visual outcomes. However, successful postoperative recovery largely depends on patients' adherence to prescribed eye medications and their ability to perform appropriate self-care practices during the early recovery period. Inadequate medication adherence may lead to preventable complications such as infection, inflammation, or delayed healing, which can negatively affect surgical outcomes and vision-related quality of life.

This randomized controlled trial aims to evaluate the effectiveness of periodic education provided to older adults undergoing cataract surgery on medication adherence, postoperative complication rates, and vision-related quality of life. Eligible participants will be randomly assigned to either a routine care group or a periodic education intervention group.

Participants in the intervention group will receive structured education regarding correct eye drop administration, medication schedule adherence, hygiene practices, and postoperative care recommendations. Educational support will be delivered at predetermined intervals following surgery through face-to-face sessions and follow-up contacts to reinforce adherence behaviors.

Primary and secondary outcomes will be assessed during follow-up visits within the first three weeks after surgery. Medication adherence levels, incidence of postoperative complications, and changes in vision-related quality of life will be evaluated using validated assessment tools.

The results of this study are expected to provide evidence on the effectiveness of structured periodic education in improving postoperative self-management and recovery outcomes among older adults undergoing cataract surgery.

Treatment and study plan

Periodic Education

Behavioral

Participants in this group receive structured periodic education in addition to routine postoperative care. The education includes instruction on correct eye drop administration, medication adherence, hygiene practices, and recognition of complication symptoms, reinforced during follow-up visits on postoperative days 6, 14, and 21.

Routine Postoperative Care

Behavioral

Participants in this group receive standard postoperative care routinely provided in the ophthalmology clinic, including discharge instructions and scheduled follow-up visits, without additional structured education.

Primary outcomes

  1. Medication Adherence to Prescribed Eye Drops

    Time frame: Postoperative Day 28

    Medication adherence will be assessed using the Modified Morisky Medication Adherence Scale (MMAS-6). The MMAS-6 consists of 6 items and yields a total score ranging from 0 to 6, with higher scores indicating better medication adherence.

Secondary outcomes

  1. Vision-Related Quality of Life

    Time frame: Postoperative Day 28

    Vision-related quality of life will be assessed using the National Eye Institute Visual Function Questionnaire (NEI VFQ-25). The NEI VFQ-25 consists of 25 items and generates a composite score ranging from 0 to 100, with higher scores indicating better vision-related quality of life.

  2. Postoperative Complication Rate

    Time frame: Postoperative Day 28

    The incidence of postoperative complications (infection, inflammation, corneal edema, increased intraocular pressure, or delayed healing) will be recorded as the proportion of participants experiencing at least one complication during scheduled postoperative follow-up visits up to day 28.
