Second eye cataract surgery improves vision, QoL better than first eye surgery alone
Second eye cataract surgery provides greater improvement in visual function and quality of life compared with first eye cataract surgery alone, a recent study claims.
Researchers analysed a total of 328 patients (mean age 70.4 years) undergoing separate first eye and second eye phacoemulsification cataract surgeries. Those with previous ocular surgery, postoperative endophthalmitis, postoperative retinal detachment, reoperation within 30 days, dementia, anxiety disorder, hearing difficulty or history of drug abuse were not included in the cohort study.
Complete pre- and postoperative ophthalmic examinations were given to patients for first and second eye cataract surgeries. Best-corrected visual acuity (BCVA) was measured 30 to 90 days pre- and postoperatively.
Patients completed the National Eye Institute Visual Functioning Questionnaire (NEI-VFQ) 30 to 90 days pre- and postoperatively. Researchers calculated the NEI-VFQ scores using a traditional subscale scoring algorithm and a Rasch-refined approach producing visual function and socioemotional subscale scores.
First eyes had worse mean preoperative BCVA compared with second eyes (0.55 vs 0.36 logarithm of the minimum angle of resolution [logMAR]; p<0.001), better mean postoperative BCVA improvement (‒0.50 vs ‒0.32 logMAR; p<0.001) and slightly worse BCVA after surgery (0.06 vs 0.03 logMAR; p=0.039).
Second vs first eye surgery resulted in greater postoperative NEI-VFQ scores for almost all traditional subscales (p<0.001), visual function subscale (‒3.85 vs ‒2.91 logits; p<0.001) and socioemotional subscale (‒2.63 vs ‒2.10 logits; p<0.001).
Visual function scores were better in first vs second eye surgery (‒2.99 vs ‒2.67 logits; p=0.021). However, both first and second eye surgeries had similar improvements in socioemotional scores (‒1.62 vs ‒1.51 logits; p=0.255).
“For certain socioemotional aspects of quality of life, second eye cataract surgery results in comparable improvement to first eye cataract surgery,” researchers said.
