Abstract Details

Purpose:

The aim of this study is to evaluate the dominance change in patients who underwent cataract surgery in only one eye, and to investigate which factors are associated with dominance changes.

Setting:

Department of Ophthalmology, Konkuk University Medical Center, Seoul, Republic of Korea.

Methods:

A retrospective study was conducted on 57 patients who underwent unilateral cataract surgery. Patients were divided into two groups according to their dominance change and then analyzed by several factors. These include whether the operated eye was the patient’s dominant eye, pre and postoperative spherical equivalence, spherical equivalent differences in both eyes, uncorrected distant visual acuity (UCDVA), uncorrected near visual acuity (UCNVA), best corrected visual acuity (BCVA). All factors went through logistic regression analysis.

Results:

Among 57 patients, eye dominance changed in 18 patients (31.6%). 18 patients underwent cataract surgery on their dominant eye, and eye dominance changed in 3 patients (16.7%). Likewise, among 39 patients who had cataract surgery on their non-dominant eye, 15 patients (38.5%) developed eye dominance change. However, there was no correlation between the dominancy of operated eye and dominance changes. Preoperative UCDVA and UCNVA in non-dominant eye was decreased in dominance change group, with UCDVA found to be a statistically correlated factor.

Conclusions:

In 57 patients with unilateral cataract surgery, 18 patients (31.6%) showed eye dominance change. There was no statistically significant correlation between dominancy of operated and dominance change after cataract surgery in one eye. The lower the preoperative UCDVA in non-dominant eye, the more likely it is that the dominancy changes after cataract surgery.
