Abstract
Background: Posterior Capsular Opacity (PCO) can disrupt a patient's vision and is a prevalent challenge medical professionals face in restoring visual clarity after cataract surgery. Various evaluation methods can be employed to measure visual improvement and the efficacy of Nd: YAG Laser Capsulotomy. One such method is Retinometry, which harnesses interference patterns of light on the retina as light passes through the pupil to provide patients with relevant information regarding the potential outcomes of Nd: YAG Laser Capsulotomy. This study aims to review the efficacy of the potential vision test "Retinometry" in patients with posterior capsular opacity before and after Nd: YAG Laser Capsulotomy. Methods: Literature searching was conducted using six online databases (PubMed, Scopus, Science Direct, Clinical Key, and Google Scholar). Search terms included a combination of main keywords: "Retinometer", "Posterior Capsulotomy", "Nd: YAG laser", and "Visual Acuity". Results: A total of 5 articles were included in this review. It’s found that the retinometer visual potential test has a function in evaluating the effects that occur and visual function after Nd: YAG laser capsulotomy. Due to the increasing incidence of cataract surgery, the rise of IOL placement will increase the risk of PCO formation and the need for Nd: YAG capsulotomy. Conclusion: Posterior Capsular Opacity (PCO) management remains a significant concern in patients post-cataract surgery, given its potential to disrupt visual acuity. Neodymium-doped Yttrium Aluminum Garnet (Nd: YAG) laser capsulotomy is a practical approach for addressing PCO-related visual impairment. Still, its impact on visual improvement may be modest, especially regarding refractive measurements. The type of lens used does not significantly influence the procedure outcomes. As the incidence of cataract surgery continues to rise, the prevalence of PCO and the need for Nd: YAG capsulotomy are likely to increase.
