目的研究预先进行晶体核劈开技术在白内障超声乳化术中的应用,评价其临床疗效。方法将2组白内障患者进行比较,A组采用超声乳化前进行晶体核的劈开技术,B组手术中采取刻槽术式进行比较,观察手术中及手术后的并发症。结果术后30d视力:A组术后视力≥0.5者占62.23%;B组:术后视力≥0.5者占44.90%。术后1d角膜内皮水肿情况:A组:轻度水肿占30.19%,中度水肿占16.98%,重度水肿:无。B组:轻度水肿占53.06%,中度水肿占24.45%,重度水肿占4.08%。虹膜炎症反应:A组:2例,B组:5例。手术中后囊膜破裂:A组:2例,B组:9例。结论预先进行晶体核的劈开具有能较好的维持前方稳定性,手术时更安全,减少术后眼内反应,是理想的手术方式。
Objective To study the clinical application of phacoemulsification and phacoemulsification in cataract phacoemulsification. Methods Two groups of cataract patients were compared. Group A was split with crystal nuclei before phacoemulsification. Group B was operated with notch technique to observe intraoperative and postoperative complications. Results 30d postoperative visual acuity: A group of postoperative visual acuity ≥ 0.5 accounted for 62.23%; B group: postoperative visual acuity ≥ 0.5 accounted for 44.90%. The situation of corneal endothelial edema on day 1 postoperatively was as follows: group A: mild edema accounted for 30.19%, moderate edema accounted for 16.98%, severe edema: no. Group B: mild edema accounted for 53.06%, moderate edema accounted for 24.45%, severe edema accounted for 4.08%. Iris inflammatory reaction: A group: 2 cases, B group: 5 cases. Posterior capsular rupture in surgery: A group: 2 cases, B group: 9 cases. Conclusion It is an ideal surgical method to pre-split the nucleus of the nucleus to maintain the anterior stability better, safer operation and reduce postoperative intraocular reaction.
