Summary
Ophthalmology trainees experience increased physiological stress during phacoemulsification cataract surgery, particularly in later stages. Addressing these stress levels is crucial for improving surgical training and trainee well-being.
Area of Science:
- Ophthalmology
- Surgical Education
- Physiology
Background:
- Intraoperative stress impacts surgical performance and trainee well-being in precise ophthalmic surgeries.
- Phacoemulsification cataract surgery presents unique challenges for trainees due to its micro-level precision requirements.
Purpose of the Study:
- To evaluate subjective stress and objective physiological responses in ophthalmology trainees during phacoemulsification cataract surgery.
- To identify factors influencing stress levels and physiological changes in surgical trainees.
Main Methods:
- Cross-sectional study involving 59 ophthalmology residents and fellows.
- Recorded systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and SpO2 during key surgical steps.
- Assessed perceived stress using the Perceived Stress Scale (PSS-14).
Main Results:
- SBP and HR significantly increased during surgery, peaking during lens removal and IOL implantation.
- Less experienced trainees showed higher DBP trends.
- Female surgeons and less experienced trainees reported higher perceived stress (PSS-14).
Conclusions:
- Physiological stress responses increase during cataract surgery, influenced by experience and individual factors.
- Findings highlight the need for targeted strategies to support ophthalmology trainee well-being.
- Improving surgical training environments is essential, especially for susceptible individuals.

Psychological Responses to Stress
Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...
Physiological Foundation of Stress
Stress triggers a coordinated physiological response involving the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis. This dual activation ensures that the body is prepared for both immediate and prolonged stress management. The process begins with the perception of a stressor. This initial phase activates the SNS, leading to the rapid release of adrenaline (epinephrine) from the adrenal glands.

Accessory Structures of the Eye
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
