Prevalence of Binocular Vision Anomalies Before and After Cataract and Refractive Surgery

Detailed Summary

There are indications in the literature that binocular vision disorders may occur after cataract and corneal refractive surgery. It is not clear whether these problems are new or represent decompensation of previously existing conditions. However, the following significant study limitations exist in the current literature: 1) lack of attention to non-strabismic binocular vision disorders, 2) incomplete binocular vision assessment, 3) a validated symptom survey was not used, 4) diplopia was typically the only symptom studied, 5) retrospective study design, and 6) in the few prospective studies the sample sizes were small. Given the limitations in the current literature there is a need for further study of the prevalence and significance of binocular vision problems after cataract surgery and binocular vision and accommodative problems after corneal refractive surgery. This study aims to determine whether there is an increase in the prevalence of binocular vision problems after cataract surgery and accommodative and binocular vision disorders after refractive surgery.
