To evaluate the frequency and risk factors for persistent post-surgical pain (PPP) after cataract surgery, defined as mild or greater dry eye (DE)-like symptoms 6 months after surgery.
The single center study population included 86 individuals who had cataract surgery between June-October 2016 and had DE symptom information available 6 months after surgery. Patients were divided into 2 groups: controls were defined as those without DE symptoms 6 months after surgery (defined by a Dry Eye Questionnaire 5 (DEQ5) score<6), cases were defined as those with mild or greater DE-like symptoms 6 months after surgery (DEQ5≥6).
The mean age of the study population was 71 years±8.6; 95% (n=82) were male. DE-like symptoms were reported in 32% (n=27) of individuals 6 months after cataract surgery; 10% (n=8) reported severe symptoms (DEQ5≥12). Patients with DE-like symptoms after cataract extraction (CE) also had higher ocular pain scores, and specific ocular complaints (ocular burning, sensitivity to wind and light) compared to controls with no symptoms. A diagnosis of non-ocular pain increased the risk of DE-like symptoms after cataract surgery (OR 4.4, 95% confidence interval (CI) 1.58-12.1, P=0.005).
Mild or greater PPP occurred in approximately 1/3 of individuals after cataract surgery. The prevalence of severe PPP is in line with that of refractive surgery, dental implants, and genitourinary procedures.
