Purpose
To develop a culturally adapted questionnaire for Chinese patients to individually select intraocular lens (IOL) type prior to cataract surgery.
Setting
Randomized controlled trial
Methods
The ITISQ was developed based on previous literature and consultations with three experienced ophthalmologists and interviews with 20 cataract patients. A total of 70 patients (97 eyes) were prospectively included in the questionnaire group (Q group) and 76 patients (96 eyes) in the control group (C group). The IOL types were selected through the ITISQ and traditional conversation in the Q group and C group, respectively. The Catquest-9SF questionnaire was filled out at 3 months after surgery to compare the postoperative satisfaction and subjective visual quality between the two groups. Test-retest reliability was verified in 42 patients in the Q group.
Results
The Spearman correlation coefficients of each item ranged from 0.406 to 0.990 (P<0.01). The average time to complete the ITISQ was 3.2 min. Similar proportion of patients chose monofocal IOL in the Q group (11.11%) and C group (12.50%). More pantients in the Q group chose bifocal IOL (71.60%), while more patients in the C group chose extended depth of focus IOL (26.04%). There were no statistically significant differences in visual acuity, Catquest-9SF scores, and satisfaction scores between the two groups at 3 months after surgery. However, the satisfaction score was numerically higher in the Q group (88.2 vs 86.7), and a higher proportion of patients in the Q group chose "very satisfied" in the satisfaction rating (38.6% vs 32.9%).
Conclusions
As a simple auxiliary tool, the ITISQ may help ophthalmologists and patients select IOL types more individually and achieve better postoperative satisfaction.
