简介:目的探讨青光眼术后白内障超声乳化手术适应症、时机、手术方法和并发症。方法回顾性分析2002年1月至2004年2月青光眼术后白内障患者44例,其中预防性虹膜周边切除术8例,滤过性手术36例。对39例术前眼压控制在正常范围或仅局部药物能控制正常的病例做上方透明角膜内切口或颞侧角膜缘巩膜隧道切口,避开功能滤过区行白内障超声乳化术;对3例术前眼压须全身药物才能控制的病人,控制眼压后避开原手术区行白内障超声乳化联合小梁切除术。随访半年。结果视力均有不同程度提高结论,0.5以上33例,视觉电生理检查视功能损害与术前有明显差别,眼压均在正常范围。结论超声乳化手术是治疗青光眼术后白内障的有效方法。
简介:目的探讨和评估微型角膜刀准分子激光角膜上皮瓣下磨镶术(epipolislaserinsitukeratomileusis,Epi—LASIK)与准分子激光角膜上皮瓣下磨镶术(laserepithelialkeratomileusis,LASEK)治疗中高度近视的安全性和有效性。方法Epi-LASIK组31例(59眼)和同期LASEK39例(75眼),Epi—K微型角膜上皮刀(平推型)进行Epi—LASIK术(MoriaEpi刀须负压45S才达到规定指标)。LASEK采用20%乙醇浸润20~30S,临床观察两者术后症状、视力、角膜上皮瓣愈合特点及视觉质量等。结果Epi—LASIK组术后6个月裸眼视力达术前矫正视力占92.35%,LASEK组术后6个月裸眼视力达术前矫正视力占93.83%。主要并发症有术后部分少许角膜上皮下雾状混浊(Haze)形成及继发高眼压。两组术后对比敏感度提高,出现眩光差异无显著性意义。结论Epi—LASIK及LASEK术均可安全,有效的矫治中高度近视。两者的长期疗效有待观察。
简介:目的:分析抗血管内皮生长因子(VEGF)药物加Ahmed青光眼引流阀(AGV)对新生血管性青光眼(NVG)的疗效和安全性。方法:选取2020.01-2020.11本院收治的NVG患者10例为研究对象,均通过抗VEGF药物加AGV开展治疗,观察术后不同时间的手术成功率;术前及术后不同时间的眼压水平、视力改变、视功能受损眼病患者生活质量评定量表(QOL)评分和并发症情况。结果:术后1d及1周,手术成功率达到100.00%,后伴随时间延长有轻微下降,但术后不同时间的手术成功率相比无显著差异(P>0.05)。术后1d及1周,眼压水平较术前显著下降(P<0.05),至术后1个月眼压有轻度升高,但仍低于术前(P<0.05),术前及术后眼压水平相比差异显著(P<0.05)。术后1d及1周,视力提升比例达到100.00%,术后1个月开始有轻微下降,但术后不同时间的视力水平相比无显著差异(P>0.05)。术后,患者QOL评分术前显著升高(P<0.05),至术后1个月QOL评分有轻度下降,但仍高于术前(P<0.05)。10例患者中1例出现前房少量出血,1例出现轻度角膜水肿,均未经特殊处理后自行消失,无1例出现严重并发症。结论:抗VEGF加AGV对NVG患者疗效确切,能改善其视力,降低其眼压水平,且安全性较高,值得采用。
简介:目的:对比观察TransPRK与LASEK术治疗高度近视的临床疗效。方法:选择行激光矫正的高度近视患者120例240眼。随机分TransPRK术组60例120眼,LASEK术组60例120眼。观察术后1wk眼部刺激症状、术后2wk视力、术后3mohaze的发病率、术后1a屈光度等。结果:两种方法均取得良好的手术效果。术后第1dTransPRK组无刺激症状者:86眼(71.7%),视物清楚,睁眼来医院复查。LASEK组术后81眼(67.5%)无刺激症状;术后2wk视力与术前矫正视力比较,TransPRK组109眼(90.8%),LASEK组87眼(72.5%);术后3mohaze的发病率,TransPRK组0级113眼,LASEK组0级109眼。结论:TransPRK组刺激症状明显轻于LASEK组,TransPRK组比LASEK组术后视力恢复快;TransPRK组比LASEK组术后haze的发病率低,以上均有统计学差异(P〈0.01);术后两组1、3、6、12mo两组视力、屈光状态、视觉质量均无统计学意义(P〉0.05)。两种手术方式矫正高度近视疗效无明显差异,均具有较好的安全性、有效性及可预测性。
简介:超声乳化白内障摘除术虽具有许多优点,但也存在许多不足,通过对激光的认识和了解,使其有可能应用于白内障手术,Nd:YAG激光较超声乳化白内障摘除术更加安全,对局部组织无损伤,手术时切口更小,手术后散光轻,操作简单.这一技术将使白内障手术效果更趋于完美.
