Phacofragmentation of Posteriorly Dislocated Lens Fragments: Limbal versus Pars Plana Approach.
Purpose: To assess intra-operative complications and feasibility of removing crystalline lens fragments from the vitreous cavity through a limbal incision compared to a pars plana approach.
Design: Retrospective cohort study.
Subjects: 16 eyes underwent phacofragmentation via a limbal approach (Group A) and 9 eyes through a pars plana approach (Group B) at an academic center over a 10-year period.
Methods: We collected pre-operative, intra-operative, and post-operative data. We compared rates of intraoperative complications, including corneal wound burn, iris or capsular damage, retinal tears, and hemorrhage, and recorded post-operative BCVA and IOP measurements at the one-month post-operative appointment. We also compared rates of post-operative complications, including corneal edema, choroidal detachment, or retinal detachment.
Main outcome measures: Primary outcomes of the study were the rates of intraoperative complications and the feasibility of crystalline lens removal with the limbal approach. We defined the latter outcome as the ability to complete lens removal without switching to the pars plana route.
Results: Mean BCVA for group A was 1.6, and for group B was 2.0 (p = .19). There was no significant difference between the two groups in the incidence of intraoperative complications, including corneal wound burn, iris damage, anterior capsular tear, iatrogenic retinal tear, or suprachoroidal hemorrhage (p > .99). There was no significant difference in the incidence of intra-operative vitreous hemorrhage (p = .36). Additionally, there was no significant difference in post-operative corneal edema (p = .27), choroidal detachment (p = .52), or retinal detachment (p > .99). The mean post-operative BCVA was 1.0 in group A and 1.0 in group B (p = .75). We completed all cases in group A using the limbal approach without switching to the pars plana route.
Conclusion: Phacofragmentation through a limbal incision provides a feasible option for dropped nuclear fragment removal and is not associated with a higher risk of complications than the pars plana route.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
