摘　　要：目的:评估连续过夜配戴博士伦PV接触镜的治疗应用的指征与疗效。方法:非随机选用中山眼科中心的门诊与住院病例29例31只眼,包括需要缓解疼痛与刺激症,保护角膜和促进角膜创面愈合等病例。采用PV镜片连续过夜配戴治疗的同时,根据眼病性质、局部适当给予抗生素或人工泪液,定期检查或询问疼痛缓解情况、眼部改变、镜片的配适状态、镜片沉淀物以及眼部并发症。结果:病例共29例(31只眼),观察时间3～57d。平均20.9d,眼病包括大泡性角膜病变(6例6只眼),角膜炎合并小穿孔或后弹力层膨出5例(5只眼),化学烧伤上皮缺损6例(7只眼),角膜移植术或创伤缝线刺激3例(3只眼),丝状角膜炎3例(3只眼),角膜上皮糜烂2例(3只眼),反复性角膜上皮剥脱症1例(1只眼),角膜板层裂伤与上皮缺损1例(1只眼),外伤性白内障摘除术后持续上皮溃疡1例(1只眼),角膜缘移植联合羊膜移植术后1例(1只眼)。用于缓解疼痛与刺激症为目的者21例(22只眼),疼痛完全缓解或部分缓解达100%。促进角膜愈合者20例(22只眼);完全治愈15例(16只眼)占72.7%,部分改善者4例(5只眼)占22.7%。绷带保护角膜21例(23只眼),其中20例22只眼(95.7%)均有满意的保护作用,仅1例因配适不良无效。结论:PV角膜接触镜对于多种角膜病、眼表病、及角膜术后角膜保护、促进角膜愈合和缓解疼痛刺激等有显著疗效;镜片具有高透氧性能及抗沉淀性好,可大大减少眼部合并症发生的危险,这种新型的镜片可作为理想的首选的治疗性应用镜片。Purpose:To evaluate the indications and effects of continuously wearing the Bausch & Lomb Pure-Vision (PV)Contact Lens. Method:Twenty-nine patients (31 eyes) who required therapeutic contact lens wear were selected non-randomly from Zhongshan Ophthalmic Center for wearing (Pure Vision,PV) contact lens. Therapeutic indications included pain and irritation relief, corneal protection,and enhancement of corneal wound healing. Simultaneously antib-iotics and artificial tears were used according to the ocular diseases. And then, the effect of treatment, anterior segment of eyes, contact lens fitting characteristics, lens deposits and the presence of contact lens-relative complications were evaluated. Results:The duration of PV contact lens wear on 31 eyes were 3～57 days, averagely 20.9 days. Patients included bullous keratopathy (6 cases, 6 eyes), keratitis incor-porated with descemetocele (5 cases, 5 eyes), chemical burns with epithelial abrasions (6 cases, 7 eyes), post-keratoplasty (3 cases, 3 eyes), filamentary keratitis (3 cases, 3 eyes), corneal epithelial erosion syndrome (2 cases, 3 eyes), repetitive corneal epithelial stripping syndrome (1case, 1eye), corneal lamellar laceration and epithelial coloboma(1 case, 1 eye), post-extraction of traumatic cataract with durative corneal ulcer (1 case, 1 eye), post-limbal & amnia transplantation (1 case, 1 eye). For the treatment of pain and irritation relief (21 patients, 22 eyes), all patients had complete or partial relief. For corneal healing (20 patients, 22 eyes), full healing was noted in 15 patients (16 eyes) (72.7%), partial healing occurred in 4 patients (5 eyes) (22.7%). For corneal protection (21 patients, 23 eyes), lens wear was fully protective in all cases, except one case of loosely fitting. Conclusion: Our result shows that PV Contact Lens exhibits prominent efficiency in treating corneal diseases and ocular surface diseases, as well as corneal protection, corneal healing and pain relief. The lens has increased oxygen transmissibility and good anti-dep
