PURPOSE: To explore the features of the dominant and nondominant eyes in patients with cataracts and predict ocular dominance shift (ODS) based on preoperative indicators.
SETTING: Changsha Aier Eye Hospital, Changsha, Hunan, China.
DESIGN: Prospective, observational study.
METHODS: Patients with age-related cataracts who underwent unilateral cataract surgery were enrolled in this study. Before the procedure, uncorrected distance visual acuity (UDVA) was assessed and noncycloplegic subjective refraction evaluations were conducted to determine corrected distance visual acuity. Total astigmatism, corneal astigmatism, and intraocular astigmatism were measured using OPD-Scan III. Cataract type was assessed using slitlamp biomicroscopy based on the Lens Opacities Classification System III. Ocular dominance (OD) was determined under corrected conditions using the hole-in-card test. Follow-up visits occurred at 1 day, 1 week, and 1 month postoperatively. After 1 month, OD was re-evaluated, and participants completed the 9-item Short-Form Cataract Questionnaire.
RESULTS: 94 patients (188 eyes) were enrolled in the study. The analysis showed that the ODS rate of unilateral cataract surgery was 40.4%. In addition, age, UDVA of the nondominant eye, posterior subcapsular cataract, and total astigmatism were risk factors for ODS. No difference in vision-related quality of life was detected between patients who had ODS and those who did not.
CONCLUSIONS: Several preoperative parameters as potential risk factors of ODS after cataract surgery were identified. These findings provide guidance for predicting changes in the dominant eye and may improve the precise selection of intraocular lenses and implementation of monovision strategies.
