穿透性角膜移植50例的临床研究

目的:探讨穿透性角膜移植的疗效和相关并发症。方法:对50例(50眼)穿透性角膜移植进行回顾性分析。结果:统计分析表明:角膜植片透明者45例(90%),视力≤0.04者6例(12%),0.05～0.2者27例(54%),≥0.3者17例(34%)。主要并发症:角膜植片免疫排斥反应6例(12%),继发性青光眼4例(8%)。结论:穿透性角膜移植是提高角膜盲视力的有效手段,应重视防治术后免疫排斥反应。

Clinical research of penetrating keratoplasty in 50 cases

AIM:To study the clinical effect and complication of penetrating keratoplasty.METHODS:A total of 50 cases with penetrating kerato-plasty was retrospectively studied.RESULTS:Due to immunologic rejection,secondary glaucoma and other causes,corneal transparence of 5 cases(10%)was influenced.And other 45 cases(90%)had corneal graft transparent.The postoperative visual acuity was ≤0.04 in 6 cases(12%),0.05-0.2 in 27 cases(54%),and ≥0.3 in 17 cases(34%).The main compl-ications were immune rejection on the graft in 6 cases(12%),secondary glaucoma in 4 cases(8%).CONCLUSION:Penetrating keratoplasty can help the patients to regain their sight.But the prevention and treatment of keratoplasty rejection is a key factor to the success of operation.
