Lived experiences and perception of visuomotor impairment in older adults following first- and second-eye cataract surgery

Technical Summary: Lived Experiences and Perception of Visuomotor Impairment in Older Adults Following First- and Second-Eye Cataract Surgery

Problem Statement
Despite cataract surgery being the most common elective surgery in the UK, significant variation persists in eligibility criteria and provision timing across Clinical Commissioning Groups (CCGs). While quantitative research links reduced vision to increased fall risks, driving accidents, and diminished quality of life (QoL), findings remain inconclusive due to methodological limitations. Specifically, reliance on laboratory-based tasks or standardized questionnaires often fails to capture the nuanced, lived experience of visuomotor impairment. Furthermore, existing literature frequently overlooks the specific impact of motor skill degradation on daily independence and the subjective differences between first- and second-eye surgery outcomes. There is a gap in understanding how older adults perceive and adapt to visuomotor challenges in real-world settings while awaiting or recovering from surgery.

Methodology
This study employed an exploratory qualitative design utilizing semi-structured focus groups to investigate the lived experiences of older adults regarding cataracts and surgery.

• Participants: Nine participants (mean age 80.11 ± 8.49 years; 8 female) were recruited. Seven had undergone bilateral cataract surgery (with inter-surgery intervals ranging from 1 to 60 months), and two were awaiting first-eye surgery.
• Procedure: Four focus groups were conducted (three post-surgery, one pre-surgery). Sessions were held both online (Microsoft Teams) and in-person at the University of Leeds, lasting approximately one hour.
• Data Collection: Researchers facilitated discussions using semi-structured interview guides covering motivations for surgery, pre-surgery motor skill experiences, quality of life impacts, post-surgical visual and motor adaptation, and interactions with healthcare providers.
• Analysis: Data were analyzed using exploratory thematic analysis guided by a biopsychosocial theory of ageing. Transcripts were coded independently by two researchers, with discrepancies resolved through discussion. Analysis was iterative, moving from initial coding to the identification of latent themes and sub-themes using NVivo software.

Key Contributions
This research contributes to the literature by:

1. Shifting Focus to Visuomotor Function: Unlike previous studies focusing primarily on visual acuity or general QoL, this study explicitly investigates the intersection of visual impairment and motor skill performance (both fine and gross motor skills) in daily life.
2. Qualitative Depth: By utilizing focus groups rather than questionnaires, the study captures social and emotional insights, including the "amazement" at visual restoration and the specific psychological barriers to activities like driving, which quantitative measures may miss.
3. Comparative Perspective: The inclusion of both pre-surgical and post-surgical participants allows for a comparison of expectations versus lived realities, highlighting the specific challenges of the interim period between first- and second-eye surgeries.
4. Healthcare System Critique: The study identifies specific systemic issues, such as inconsistent information regarding driving eligibility and surgical access, which directly impact patient anxiety and adaptation.

Results
Thematic analysis yielded four primary themes and eight sub-themes:

1. Adaptation to Visual Changes:

   • Amazement: Participants reported immediate, often surprising improvements in brightness, clarity, and color perception following surgery. Some awaiting surgery expressed high anticipation for these specific changes.
   • Confidence: Restoration of vision led to renewed personal confidence, particularly regarding independence from corrective lenses and the belief in the durability of intraocular lenses.

2. Motor Adaptation and Activities:

   • Driving: Pre-surgery, participants reported significant anxiety regarding driving, particularly at night or in adverse weather, leading to reduced independence. Post-surgery, driving confidence and safety were restored, enabling social participation.
   • Meaningful Activities: Participants described difficulties with fine motor tasks (threading needles, knitting) and gross motor tasks (golf, pétanque) due to visual deficits. Surgery facilitated a return to these activities, though some noted that physical limitations unrelated to vision persisted.

3. Lifestyle Maintenance and Resilience:

   • Social Support: Visual impairment often led to social withdrawal (e.g., inability to attend the theatre or care for grandchildren). Surgery was viewed as a tool to maintain social circles.
   • Adapting to Difficulties: Participants demonstrated resilience, employing strategies (e.g., magnifying glasses) to cope with visual deficits between surgeries. However, many struggled to distinguish between age-related motor decline and cataract-induced impairment, often attributing difficulties to "getting old" rather than vision loss.

4. Interactions with Healthcare:

   • Inconsistency of Information: Participants reported conflicting advice from opticians, surgeons, and other providers regarding driving eligibility and surgical necessity, causing confusion and stress.
   • Accessibility: While some found the system efficient, others faced frustration with long wait times and a "conveyor belt" approach that lacked personalized accommodation for specific physical limitations (e.g., inability to lie flat for examination).

Significance and Claims
The paper argues that visuomotor ability is critical for maintaining independence and that cataract surgery significantly enhances quality of life by restoring motor confidence and social participation. The authors claim that:

• Qualitative methods are essential: Conversational approaches reveal motor difficulties and driving anxieties that objective measures or questionnaires may fail to detect, particularly when participants attribute deficits to age rather than cataracts.
• Second-eye surgery is vital: The study supports the provision of second-eye surgery to minimize the period of adaptation and risk to quality of life, noting that the interim period between surgeries can be particularly challenging.
• Healthcare consistency is required: There is an urgent need for consistent information across healthcare providers, specifically regarding driving safety and post-operative expectations, to reduce patient anxiety.
• Policy Implications: The findings suggest a need to reduce wait times between first- and second-eye surgeries and to develop more comprehensive eligibility criteria that account for the lived experience of visuomotor impairment rather than arbitrary visual thresholds.

The authors maintain a modest tone, acknowledging that the small sample size limits generalizability, but assert that the findings align with previous research while illuminating "blind spots" in current healthcare provision and eligibility criteria.
